Development of an AI mobile application for children's fairy tales

Budget: 3000 UAH Deadline: 3 days

Hello! My name is Oleg, I am the project manager at Business Atlas. Creating mobile applications with AI, setting up secure content generation systems, and building cross-platform architecture are our core cases. We are ready to develop a turnkey app for iOS and Android based on a stable Low-code backend and modern mobile stack. Here is our technical vision and optimization of your specifications:
1. Technological solution and architecture
• Cross-platform (iOS / Android): Development on Flutter or React Native will provide a single codebase for both platforms, a premium interface, and significant budget savings.
• Low-code backend (n8n / Make): The AI logic will be placed on flexible workflows, allowing you to easily add new fairy tale topics or change AI models in the future without rewriting the app code.
• Generation ecosystem: We will combine text models (OpenAI / Claude), illustration generation services, and Text-to-Speech solutions for realistic narration of fairy tales into one seamless process.
2. Implementation of AI generation and content protection
• Age adaptation: The parameters "age", "name", and "topic" will become system filters for generating plots of varying complexity for children aged 3 to 6 years.
• Multi-level AI censor: We will implement a cross-validation system. The first AI agent generates a fairy tale, and the second analyzes the finished text and blocks the output if it finds the slightest deviation from child safety norms.
• Plot database (RAG): We will upload a database of classic good and therapeutic fairy tales into the system, which the AI will use as a benchmark for creating new stories without hallucinations.
3. Timelines and implementation cost
• MVP (Phase 1 — 3-4 weeks): Creation of the basic app, setup of text and illustration generation, launch of a personal library.
• Full launch (Phase 2 — 2-3 weeks): Integration of narration (Text-to-Speech), expansion of topics, and final setup of the AI censor.
• Total timeline: 5 – 7 weeks.
• Turnkey project cost: $4,500 – $7,000 (one-time, depending on the final pool of API tools).
Message me privately. We will conduct a brief technical diagnosis of your vision, approve the technology stack, and create a clear roadmap for launch. Expand

Budget: 20000 UAH Deadline: 30 days

I will develop an iOS/Android application for generating personalized children's fairy tales: selection of age, theme, child's name, AI text, voiceover, story library, beautiful interface, and architecture for new scenarios.

Do you already have a test set of ages, themes, and forbidden scenarios to ensure that the AI does not produce adult, disturbing, or random plots in fairy tales for children aged 3-6?

The budget and timeline for the MVP will be discussed in private correspondence after reviewing the reference, design, voiceover requirements, illustrations, and content safety system.

Budget: 27000 UAH Deadline: 20 days

Hello!
This is a very interesting project — it’s the type of product where it’s important not just to do it technically, but to do it with heart. I have experience with Flutter, AI API integrations, and mobile applications.
My vision for implementation:
Stack:
— Flutter (iOS + Android)
— OpenAI API for generating fairy tales
— ElevenLabs or Google TTS for voiceover
— Firebase (authentication + library storage)
— Stable Diffusion or DALL-E for illustrations
Content protection for children:
— System prompt with strict limitations for OpenAI
— Filtering responses before showing them to the user
— The child's age affects the complexity and theme of the fairy tale
— Only safe themes: nature, animals, friendship, adventures
Functionality:
— Selection of the child's age (3-6 years)
— Selection of theme and child's name
— AI generation of a personal fairy tale
— Voiceover + text for reading
— Personal library of saved fairy tales
— Beautiful friendly design
Timeline: 20 days
Cost: 40,000 UAH
I am ready to work in stages — first MVP with basic functionality, then expansion.
When is it convenient to discuss the details? Expand

Budget: 2500 UAH Deadline: 4 days

Creating a mobile application from scratch for iOS/Android is expensive (from $2000) and time-consuming (2 months). I propose to create an MVP (minimum viable product) in the form of a Telegram bot in 4 days and at a cost 10 times lower. The bot will do EVERYTHING the same: ask for age, name, topic, generate a fairy tale through the OpenAI API, voice it, and provide the text. You will test the hypothesis on real parents, and if it goes well, you will order the application.

Budget: 27000 UAH Deadline: 30 days

In addition to standard functionality (theme selection, naming, generation, voiceover), I offer a unique feature that will set you apart from competitors: Therapeutic "Smart Tales."
We can embed the principles of positive child psychology and cognitive-behavioral tools into the AI prompts. For example, a parent can easily choose whether to teach their child empathy today (looking at the heroes' conflict from another perspective), optimism (finding the positives in the hero's failure based on the principle of "But at least"), or transforming fear (renaming the "Monster" to "Fluffy").
For parents, this will be implemented as simple pop-up tips during the story setup — we will teach them the basics of psychology through gamification, without boring lectures. This will elevate the app's value from just "bedtime entertainment" to a "useful tool for developing a child's thinking."
This project is better realized on Bubble rather than Flutter, as Bubble combines the database and complex AI logic in one ecosystem, allowing us to launch a native app for iOS and Android twice as fast and cheaper without writing a separate backend.
My experience includes complex applications with deep AI integration.
How we will implement the project:
Generation: We will use the fast and economical gpt-4.1-mini.
Security (priority): Strict prompts and auto-content filtering. Free input is excluded — topics are selected only from a closed safe list.
Voiceover: Integration of the ElevenLabs API (warm voices) with auto-saving to a personal library.
Timeline: 4-6 weeks. You will be able to test the interface on your smartphone in a special app from Bubble from the first days of development.
Budget: 2500–4000. The subscription fee for the Bubble platform for the native app will be $49/month.
I would be happy to discuss the details! Expand

👋 Hello. My portfolio is Freelancehunt

I am interested in your project. I have experience in developing mobile applications and integrating AI services. I am ready to create a convenient application for iOS and Android that generates personalized children's stories, includes voiceovers, a library of stories, and a reliable content control system.

🤖 For AI generation, I would use modern language models with additional moderation and age restrictions to exclude undesirable topics. I will design the architecture with future scalability and the addition of new features in mind.

I am ready to discuss the project details, exact timelines, and budget, and to propose the optimal implementation option.

⏰ Timeline — 4–5 weeks
💵 Budget — from 70,000 UAH

🚀 I take every project seriously and work towards results. I do not just complete tasks; I ensure the work reaches a state where the product looks high-quality, professional, and trustworthy to clients. Expand

Budget: 27000 UAH Deadline: 70 days

👋 Good afternoon, the best and largest projects —> Freelancehunt

I have worked with mobile applications and AI integrations, including content generation via API and building systems with filtering and quality control of output.

🔥 As I understand the task, it involves creating a cross-platform mobile application (iOS / Android) where users can generate personalized children's stories using AI, with text, voiceover, and saving to a library.

Special attention in such a product is important not only to functionality but also to content safety and stability of generation.

I propose the implementation as follows:

• Development of a mobile application (React Native or Flutter)
• Integration of an AI model for generating stories considering the child's age
• Content filtering and protection system (exclusion of unwanted topics)
• Text generation + voiceover (TTS)
• Personal library of user stories
• Administrative logic for managing topics and scenarios

🧠 For the AI part, I suggest using structured prompts + a moderation layer before outputting results to ensure completely safe children's content without random topics.

🦾 If necessary, I will involve additional developers for the mobile part and AI integration.

⏳ In terms of timelines, approximately 6–10 weeks for the MVP.

💶 Budget: $3000–6000 (depending on the depth of AI filtering, design, and voiceover)

⚡️ There are many performers, but a quality children's product is always about accuracy, stability, and attention to detail, not just about generating functionality.

🤝 I am ready to discuss the details and propose an optimal architecture for scaling and further development of the project. Expand

Budget: 700 UAH Deadline: 1 day

Hello! I am a developer with 5 years of experience in mobile applications for children and family audiences. I already have a project "Little Tales" on Android and iOS, using GPT-4 for text generation and Stable Diffusion for illustrations. The planned timeline is 3-4 months (in phases), and the budget is 12,000 USD. We will implement AI generation through the OpenAI API, add filters by age and topics, as well as a content control module based on the SafeContent model. The microservices architecture will allow us to scale and add new scenarios without restarting the application. I am ready to discuss the details and format of collaboration.

Budget: 20000 UAH Deadline: 30 days

Hello.

I am really interested in the project. I am not only a UX/UI designer but also a developer with experience in creating AI products and applications with external API integration, so I have a good understanding of both the user side and the technical implementation of such solutions.

I already have a clear idea of how to design such a product. The main task here is to create a simple, safe, and pleasant user experience where a parent can literally get a personalized fairy tale for their child in just a few minutes.

As a reference, I am well acquainted with the "Little Stories" app, but I see opportunities to make the product more modern through high-quality AI personalization, more flexible scenario generation, and scalable architecture.

Here’s how I envision the technical implementation of the MVP:

• Cross-platform development on Flutter for simultaneous launch on iOS and Android.
• Backend on Node.js/NestJS or Python FastAPI.
• PostgreSQL database for storing users, stories, settings, and a library of fairy tales.
• Storage of images and audio in AWS S3 or Cloudflare R2 cloud storage.
• Authorization via Firebase Authentication or Supabase Auth.
• Integration of the AI model through OpenAI API or Claude API for generating fairy tales.
• Integration of Text-to-Speech for narrating stories (OpenAI TTS, ElevenLabs, or Google Cloud Speech).
• Generation of illustrations through a separate AI service with additional content moderation.

I would pay special attention to the safety of children's content.

To achieve this, I would implement several levels of protection:
1. System prompts and restrictions for the AI model.
2. Moderation of user requests before generation.
3. Moderation of results after generation.
4. Text verification through a separate AI safety filter.
5. Age adaptation of content for specific age groups.

This approach practically eliminates the emergence of adult themes, aggression, unwanted content, or random model deviations.

For scaling the project, the architecture can be built modularly, allowing for future additions of:

• new genres of fairy tales;
• educational stories;
• different languages;
• new voiceovers;
• interactive scenarios;
• personal characters;
• subscription models;
• family accounts.

I also consider it important to conduct thorough security and load testing before the release:

• API audit;
• authorization vulnerability checks;
• protection of user data;
• load testing;
• testing AI filters for bypassing restrictions;
• QA testing. Expand

Greetings! The task is clear, I am ready to implement the project turnkey on the Django + Next.js stack. I suggest creating a PWA (progressive web application) instead of developing separate applications for iOS and Android.

PWA is perfectly adapted for phone screens, launches via a link, and can be added as an icon on the desktop. At the same time, it offers huge savings: there is no need to hire two different teams and depend on the strict moderation of Apple and Google. All the logic for generating fairy tales based on the child's age will work through the OpenAI API (GPT-4o), and for the absolute safety of children, I will connect the OpenAI Moderation API, which filters out any unwanted topics on the fly. We will use OpenAI TTS for voiceovers, and the stories will be saved in a personal library.

Budget: 27000 UAH Deadline: 28 days

Greetings! The idea of the application is excellent - there is indeed a lack of quality, clutter-free products for shared time between parents and children in the market. The reference "Little Stories" is wonderful in its conciseness, and creating a similar yet technologically advanced personalized service is a great challenge.

I am a backend developer and systems engineer (API, AI integration, Linux). I suggest we proceed step by step and start with the foundation - developing the server-side AI core of the application. In the end, you will have a fully functional "heart" of the project and interactive API documentation (Swagger). With this ready core, in the second stage, any Flutter developer will be able to quickly connect the interface for iOS/Android.

Technical implementation and content security:
1. Architecture: API on Laravel/Symfony + Redis for content generation queues without hangs.
2. Security (3–6 years): We eliminate AI hallucinations with a three-layer filter: strict System Prompt (boundaries of child psychology) -> JSON-mode for strict data structure -> automatic validation through OpenAI Moderation API before the text appears on the screen. In case of failure - fallback (providing a ready-made fairy tale from the database).
3. Media layer: Text through gpt-4o/Claude, illustration generation through Midjourney/DALL-E 3 in a unified pastel style, voiceover through ElevenLabs API or OpenAI TTS (live, non-robotic voices). Caching in PostgreSQL to save on API costs.

Timeline and budget for the server stage (AI core + API):
• Timeline: ~3–4 weeks.
• Budget for the stage: $1,500 – $2,000 (divided into sprints with payment through Secure Deal).
• Estimate for subsequent assembly of the mobile part by a third-party developer: $2,000 – $3,000.

I would be happy to discuss the architecture details in the chat! Expand

Good afternoon, I have been working on the development of applications/games and integrating AI for them. I am ready to create a beautiful design that will appeal to children (I have about 4 years of experience working with children of different ages).

Budget: 27000 UAH Deadline: 75 days

We already have a nearly ready foundation for a similar AI product, which can be quickly adapted for fairy tales and launch the first working phase. We can discuss the details here on the marketplace; I'm available.))
For the timeline, the target for the MVP is 10-12 weeks, and the budget realistically ranges from $18,000 to $25,000. I’m setting the bid at $20,000 for 75 days.
We can keep it simple at the start - create iOS and Android on a single base, a server for generation, a personal library, text, voiceover, illustrations, and an admin section for themes, ages, and safety rules.
I would build the AI part not as a free chat but as controlled generation through age scenarios, forbidden topics, result checks before showing to parents, and a log of controversial generations for improving rules.
Here, I might be a bit pedantic - for a children's product, safety control is more important than just beautiful generation, because God protects the cautious.
From experience, there are relevant AI and voice projects.
https://business.ingello.com/vorfahr - AI content generation and product SaaS logic.
https://business.ingello.com/tts - text, voice, and narration, close to the fairy tale part.
https://business.ingello.com/lita - a sensitive product where safety, a clear user path, and careful logic are important.
Our profile on complex systems and AI - https://systems-fl.ingello.com
From you at the start, I need reference applications, a list of themes, content restrictions, the desired voiceover model, and Apple and Google access will be needed closer to publication.
I’ll clarify two points - are unique illustrations needed for each fairy tale through AI, or is a beautiful library of styles sufficient at the first stage?
And the second question - is a subscription, trial period, and payment needed in the MVP, or should we first create a friendly product without monetization to test parents' interest? =/ Expand

I have been working as a fullstack developer for 3.5 years, specializing in TypeScript, Vue/Nuxt, React/Next.js, NestJS, and PostgreSQL. I have created web products from scratch, including integration with external APIs and AI models.

For your project, I envision the following solution: a React Native application with AI-generated fairy tales through an LLM API, a system prompt with strict content restrictions, and automatic response verification before display. Authorization, a personal library of stories, selection of age/theme/name, voiceover through TTS, and a beautiful responsive interface. The architecture is scalable—new scenarios, themes, and features can be added without overhauling the core.

Hello. I am a React Native developer and can create a cross-platform application for iOS and Android with AI-generated personalized children's stories, voiceovers, and a personal library of tales. For generation, I will use an LLM with an additional layer of filtering and strict restrictions to ensure completely safe and age-appropriate content for children aged 3–6 years. I will immediately lay out a scalable architecture — with the possibility of adding illustrations, new scenarios, and a subscription model in the future.

Budget: 2000 UAH Deadline: 1 day

Hello!

The project is clear and interesting — especially its essence: a safe AI product for parents and children. AI generation and content control are our core areas, and we are developing the mobile part cross-platform.

How we will implement it:

iOS + Android on a single codebase (Flutter) — a simple user-friendly interface: age selection, theme, child's name, personal library.
AI generation of fairy tales for ages 3–6 — short, kind stories.
Voiceover (TTS) + synchronized text for bedtime reading.
Illustrations based on themes.
AI generation and content safety (your key question):

strictly limited prompts by age — no random "adult" topics;
a separate moderation layer that checks each fairy tale before showing it to the child;
whitelists of topics + block lists + gentle narrative style;
fallback to verified templates if generation does not pass the filter.
This provides stable, predictably safe generation — which is critical for a child audience.
Work format: we propose a phased approach (you are ready for this yourself) — MVP (generation + voiceover + library) → illustrations → scaling of topics and functions. This way, you see the result at each step and control the budget.

We are constantly working with AI/API integration and architecture for scaling. We will discuss the details and format of cooperation in private messages. Expand

Hello, to be honest, in such projects the problem usually lies not in the generation of fairy tales itself. The neural network sooner or later starts producing something off — and for a children's product, this is critical. Parents must be sure that each story will be kind, understandable, and without surprises. I regularly work with such AI scenarios and already know where things usually break down: unstable generation, unwanted content slipping through, and "dead" voiceovers. Therefore, I initially lay down control mechanisms — so that it doesn't have to be urgently fixed at release.
As a result, you will receive:
— a cross-platform application (iOS + Android)
— stable fairy tale generation
— pleasant live voiceover
— a convenient library of stories
How we will do it:
AI logic: vocabulary control, topic filtering, age adaptation
Illustrations: a unified, friendly style without random or strange results
Voiceover: natural neural voices, so it sounds like normal reading
UX: a maximally simple scenario — create a fairy tale in a couple of actions
I would like to highlight an important point: such projects are better started not with the application, but with testing the AI logic. I would suggest first creating a small prototype — this significantly reduces risks and saves budget.
Please let me know:
— if there are any preferences for the style of illustrations
— if offline access is needed in the first version
Next, I will gather a clear MVP plan with stages for you — and we can launch calmly.

Hello! I have experience in creating applications for children (you can check the reviews). I work with Flutter. Write to me - we will agree.

Budget: 27000 UAH Deadline: 1 day

Hello, I have over 5 years of experience in iOS and Android development.
1) I have repeatedly developed applications with AI (I can provide project examples in private messages).
2) The development time is 2 months, including the agreement on all functionality, as well as the development of design and business logic.
3) The cost of the "turnkey" project is about 3-5 thousand dollars, including the publication of the application.
4) If it comes to text, we work within limitations, but depending on the model, we need to choose the right ones, of course. Also, whether we need to generate images and similar things, we can discuss in private messages.
I would be happy to help you!

Hello!

This is a really cool project idea. The reference "Little Stories" perfectly conveys the essence. In a children's AI product, the main thing is not just to generate text, but to ensure 100% safety and predictability, so that the AI does not accidentally produce frightening content.

I am a full-stack developer (specializing in Python backend and mobile development in Kotlin/Android).

Here’s how I will implement safe AI generation:

Multi-layered filter: The AI does not write from scratch but works with prepared "good" plot templates. Before delivering the text to the application, it passes through the OpenAI Moderation Endpoint in milliseconds (blocking any hint of NSFW or aggression).

Voice output without waiting: I will connect the Streaming API (streaming audio). The child will not have to wait 20 seconds for the entire fairy tale to be generated — the text and voice (via ElevenLabs or OpenAI TTS) will appear paragraph by paragraph.

Why you should work with me (About budget and terms):
I will not write abstract numbers or inflate the price. I am currently finishing my master's degree, so my stable working hours online start at 12:00 and last until late at night.

This project is extremely interesting to me as a strong case, so I am ready to work for a moderately average budget that will be comfortable for both you and me. We can break the work into small stages (MVP: backend -> interface -> voice output) with minimal phased payment.

Please message me your budget expectations, and we can immediately start designing the architecture! Expand

Hello! I am ready to help you. I can work with AI. I propose to create a multi-level protection system where the text will go through special filters that instantly block any unacceptable content. Additionally, we will ensure that the user only selects from verified topics, so a child will not be able to generate anything strange. For the voiceover, I will use verified voices that sound very natural.
I offer quality and fast work.

Hello!

I am interested in your project. I specialize in developing AI solutions, chatbots, automations, and integrations with LLM models, so I understand well how to build a secure and scalable application for generating personalized children's stories.

From your description, I see the product as a simple and beautiful mobile application for parents, where the user selects the child's age, the story theme, adds a name, and the system generates a short, kind fairy tale tailored for ages 3–6. Additionally, features like voice narration, illustrations, and a personal library of saved stories can be added.

Here’s how I would implement the project:

For the mobile application, Flutter or React Native can be used to quickly obtain versions for both iOS and Android. This will allow for a faster launch of the MVP and convenient scaling of the project in the future.

The backend can be built using Python / FastAPI or Node.js. It will handle users, story generation, the story library, data storage, security, limits, future payments, and interaction with the AI API.

For text generation, OpenAI / Claude can be utilized with a separate prompt system tailored for a child audience. It’s important not just to send a request to the AI, but to establish the right logic: the child's age, theme, style, story length, safe restrictions, absence of adult themes, a gentle tone, clear language, and a positive ending.

To protect the content, I would implement several levels:

— a pre-defined limited list of safe themes;
— system rules for the AI model;
— moderation of incoming requests from parents;
— verification of the generated story before showing it to the user;
— filtering of undesirable themes, words, and plots;
— fallback logic if the AI generates an inappropriate response;
— logging of errors and controversial cases for system improvement.

For voice narration, a Text-to-Speech API can be integrated so that parents can not only read the story but also play the audio version. Illustrations can be implemented in stages: initially using a ready set of beautiful safe illustrations for the themes, and later adding AI-generated images with additional moderation. Expand

The project looks very promising. I especially liked the emphasis on safe content and the personalization of stories for children - this is exactly what distinguishes a quality product from a regular AI chat. I have experience in developing mobile applications with API and AI service integration. I can send my portfolio and examples of completed projects in private messages. Regarding timelines: an MVP of such an application typically takes 6–10 weeks depending on the final set of features, design, and requirements for voiceover, illustrations, and personal library. Regarding budget: I initially estimate the project in the range of $3,000–6,000. For an accurate estimate, we need to discuss the implementation details, choice of AI models, image generation methods, and server-side requirements. I would implement AI generation through modern LLM models with additional system constraints and multi-level content filtering. This allows generating only kind, age-appropriate, and safe stories without random adult themes. A separate result check can also be added before showing it to the user, and different generation scenarios can be set up for age groups. For the mobile part, I would recommend React Native to simultaneously release the application on iOS and Android with a single codebase and to develop the product faster in the future. I would be happy to discuss the project details and propose an optimal architecture for scaling new themes, characters, and scenarios in the future.

Hello! Your project is incredibly inspiring. I specialize in mobile development and AI integration, so I would be happy to help you create a safe, kind, and stable application for generating fairy tales. I have studied the reference ("Little Stories"). My approach will make the interface even more interactive through smart AI-generated text, illustrations, and audio in real-time.
For the tech stack, I suggest using Flutter (for optimal app performance on iOS and Android from a single codebase) and Python (FastAPI) for the backend, which will handle all AI, security, and database tasks. This will save you up to 40% of the budget compared to separate development for each platform.
Experience in AI: I know how to work with prompt engineering, caching AI responses (to save your budget on API), and real-time media content generation.
Scalable architecture: FastAPI and Flutter will allow for easy project scaling: in the future, we can add subscriptions, interactive quest generation ("choose the hero's action during the fairy tale"), animated illustrations, and translation into other languages.
Ready application for two platforms: 300 – 420 hours. Estimated timeline: 2.5 – 3.5 months. Rate: $20 per hour, totaling $6000+.
Milestone payments: I work strictly in sprints. You pay for each stage separately (for example: Design ➡️ Backend ➡️ Mobile Application ➡️ Testing and Launch) only after demonstrating the completed functionality.

Hello! I have experience in mobile application development.

The project is interesting — it’s not just an AI text generator, but a children’s mobile application where content safety, interface simplicity, and stable story generation based on the child’s age are particularly important.

I can offer a phased implementation of the MVP for iOS and Android: age selection, theme, child’s name, generation of a short story through AI, voiceover, reading text, and a personal library of stories. The architecture can be laid out in such a way that new themes, scenarios, illustrations, subscriptions, and parental settings can be added later.

I would implement AI generation through an API with strict prompts, filtering of prohibited topics, age restrictions, result moderation, and fallback scenarios to exclude "adult" or random content. Voiceover can be connected through a TTS service, and illustrations can be either ready-made stylized sets or later through a separate AI/design system.

Timeline for MVP: 2–4 weeks.
Budget: depends on design, voiceover, AI limits, and illustrations; we can start gradually with a basic version.

Please let me know:

1. Do you want to start with the MVP with text generation and voiceover, or immediately with a full version with illustrations and subscription?
2. Is there already a ready design/reference, besides the "Little Stories" app, or does UX/UI need to be developed from scratch? Expand
