Hello.

Interesting project, the stack and logic are clear. I can take on the development of such a solution turnkey.

I have experience with Telegram bots, Python/FastAPI, PostgreSQL, integrations with OpenAI API, and building AI functionality with dialogue memory, RAG, and subscription logic. In your case, we can create a really strong product where the bot will not just respond but guide the user through a learning path: levels, lessons, practice, progress, motivation, and payment — all in one system.

What I see for implementation:

— Telegram Bot API as the main interface for the student
— backend on FastAPI / Python
— PostgreSQL for users, progress, lessons, history, subscriptions
— pgvector for RAG on lessons, vocabulary, grammar, and dialogue memory
— OpenAI API for conversational training, explanations, exercise checks
— n8n for automation: daily tasks, reminders, subscription events, welcome sequences
— Stripe for subscriptions and tier limitations
— admin panel for uploading lessons, vocabulary, grammar, assignments, and managing content

Regarding functions, everything is also feasible:

— user profiles
— storing the complete history of correspondence
— division by levels A1–C1
— lessons: video, vocabulary, grammar
— exercises with checks
— AI trainer for speaking/writing practice
— XP, streaks, achievements
— daily tasks
— subscription and functional limitations by tiers Expand

Hello, Irina! I am ready to immediately take on your project and complete it efficiently and quickly. Write to me - we will discuss the details of the technical assignment, deadlines, and cost.

Budget: 20000 UAH Deadline: 10 days

Hello! I have a ready-made solution that fully meets your specifications and even exceeds them in functionality.

I have already developed and launched a similar system — Schlau AI. This is a complete ecosystem for learning the German language in Telegram, which includes:
1. An interactive learning tree (levels A1-B1) in the format of a Mini App (TWA).
2. An AI tutor based on Gemini 2.0/GPT-4o with context memory and personalized advice.
3. A gamification system: XP, levels, lives (hearts), daily quests, and achievements.
4. An integrated store and payment through Telegram Stars.
5. An admin panel for managing content and lessons.

Check out my case "Schlau AI" in the portfolio — there are screenshots of the real interface.

**Important addition regarding the stack:** Your specifications mention **n8n**. In my solution, I replaced it with a custom backend on **FastAPI**. This was done to ensure maximum speed (especially for RAG and the AI simulator) and to eliminate dependence on third-party no-code platforms. However, if it is critical for you to use n8n for certain integrations, my system can be easily connected to it via webhooks.

Since the main engine and architecture are already ready, I can adapt the system to your brand and launch it in the shortest possible time, focusing on content filling rather than lengthy development from scratch.

I would be happy to discuss the details and show a demo! Expand

Budget: 1000 UAH Deadline: 1 day

Good day, Iryna.

I have experience. An effective educational bot must combine dialogue flexibility and structured material presentation. The main task is to ensure personalization based on the interaction history and the student's knowledge level.

I will build a system on n8n/make, where the LLM will analyze progress in real-time. The following will be taken into account:
- Distributed repetitions,
- Ebbinghaus forgetting curve,
- Algorithms similar to Anki algorithms.

Using PostgreSQL with vector search will enable the implementation of long-term memory and precise exercise selection.

Integration of a payment gateway and a user-friendly interface for management will ensure monetization and easy content updates.

This approach guarantees stable service operation, flexible user motivation, and scalability of the architecture to handle increasing loads.

P.S.:
Just for the future. Since the bot involves daily tasks and gamification, consider developing a companion mobile application for convenient progress tracking, receiving notifications, and additional learning materials. This will expand your product's ecosystem and increase user retention. Expand

Hello.

I am ready to sell a bot based on your technical specifications. I work with the stack (Python, PostgreSQL, pgvector, OpenAI, Stripe), setting up RAG logic and automation.

My main advantage for this project: you will not have to wait and overpay for the development of an admin panel from scratch. I have a powerful custom admin panel built on Python/Flask, which I have developed and fine-tuned for a complex commercial project. I will simply adapt it for uploading your lessons, vocabulary, and user management. This will save development time and provide you with a stable, user-friendly tool without raw bugs.

I will write the rest of the bot's backend and AI integrations cleanly and strictly according to your requirements.

Hello 👋
Great idea, and you have chosen an exceptionally competent backend stack. However, for such a substantial functionality, I strongly recommend moving away from the classic text bot towards the Telegram Web App.
Why Web App:
Stuffing video lessons, a progress bar, vocabulary cards, and grammar tests into regular text messages of the bot means significantly spoiling the UX. The text format for learning quickly becomes tiresome. The Web App will allow for a beautiful graphical interface within Telegram (like Duolingo), which looks expensive, instills trust, and significantly better converts users into a paid subscription via Stripe.
My technical solution:
Frontend: React / Next.js. We will create a user-friendly visual shell: a dashboard with language level, series of days, a modern video player, and interactive elements for exercises.
Backend and AI core: Python (FastAPI + aiogram) + PostgreSQL. I will connect the OpenAI API with a vector database. The AI trainer will instantly pull up the history of mistakes and the student's context from pgvector and form personalized conversation practices.
Monetization and Management: Full Stripe integration. I will also develop a convenient admin panel for quickly uploading new videos, lessons, and vocabulary without the involvement of a programmer.
I specialize in developing complex architectures for Telegram Mini Apps, deep integration of AI (OpenAI, RAG systems), and educational SaaS platforms.
Message me privately, and we will discuss the architecture details in depth. I respond quickly!

Hello! Interesting project! The stack is very well chosen.

I will implement your idea through n8n, so you will be able to easily change the learning logic without touching the code. I have experience working with pgvector, so I will set up RAG to ensure that the AI provides accurate answers, working only with your database of words and grammar, without any "hallucinations."

What specifically can I do:

Architecture: I will connect OpenAI and Stripe through n8n for stable subscription and limit processing.

Gamification: I will create the logic for saving streaks and XP in PostgreSQL so that users return more often.

Admin panel: I will develop an interface for easy uploading of videos and exercises by your content managers.

Do you already have a ready lesson structure (A1–C1), or will it need to be imported from existing files? I am ready to discuss the details in private messages. Expand

Budget: 12000 UAH Deadline: 14 days

Good day, Irina!

An interesting project — essentially, this is a mini EdTech platform within Telegram. I have worked with a similar stack and understand how to assemble it correctly.

What is important and what most will overlook:

RAG for learning — pgvector is needed not just for searching, but for contextually selecting materials according to the student's level. If a student is at A2 and makes mistakes in Dative — the bot should pull up exactly these exercises, not random ones.
Memory of dialogues — not just to store history, but to build a profile of the student's mistakes. OpenAI with the right system prompt + context from the database = a personal tutor, not just a chat-bot.
Gamification that works — XP, streaks, achievements must be tied to real progress (completed topics, % correct answers), otherwise it is just decoration.
My implementation plan:

Architecture of the bot (aiogram 3 + FastAPI backend)
PostgreSQL + pgvector — profiles, progress, RAG on materials
n8n — daily reminders, triggers based on activity, automation
OpenAI integration — conversational trainer with adaptation to the level
Stripe — subscription with trial, webhook processing
Admin panel (React) — uploading lessons, vocabulary, videos
Gamification — XP, streak, daily tasks, leaderboard
I have experience with Telegram bots, OpenAI API, PostgreSQL, pgvector, Stripe integrations.

I have a question: is the content of the lessons (videos, vocabulary, grammar) already prepared, or is help needed with structuring? Expand

Hello. We can create a Telegram bot for learning German using your stack: Telegram Bot API, n8n, OpenAI, PostgreSQL with pgvector, Stripe, and an admin panel for uploading lessons and vocabulary. We will ensure that the user has a history saved, levels A1-C1 work, exercises, conversation practice, daily tasks, gamification, and a subscription.
To design it correctly from the start, I would like to clarify two points: do you already have the content (videos/lessons) or do you need help with the structure and generation, and what type of subscription model is needed, monthly or several tiers? After that, I will provide a work plan and an estimate for the timeline and budget.

Good day.

I have reviewed the project description. This is a full-fledged platform for language learning through a Telegram bot with an AI coach, a lesson system, and a subscription. Such systems require the right architecture (bot + database + AI logic), otherwise, the bot quickly starts to work unstably as the number of users grows.

I am engaged in the development of Telegram bots and AI integrations and can implement such a project:

• Telegram bot with user profiles and progress tracking
• OpenAI integration for conversational practice and error explanation
• lesson system (videos, vocabulary, exercises)
• memory of the user's dialogue history
• gamification (XP, achievements, daily tasks)
• subscription system via Stripe
• admin panel for managing lessons and content

The architecture can be built on **Telegram API + OpenAI + PostgreSQL**, with the possibility of scaling as the number of users grows.

Estimated time for MVP development: **2–3 weeks**. - 200$

I am ready to discuss the details and propose an optimal implementation architecture. Expand

Hello.

Yes, we can implement such a project. I have already worked with Telegram bots and systems that use the combination of Telegram API + OpenAI API + database, so the architecture for such a solution is clear to me.

The proposed stack looks logical:
• Telegram Bot API — interface for user interaction
• n8n — automation of scenarios and workflows
• OpenAI API — generation of responses and conversational practice
• PostgreSQL + pgvector — storage of users, chat history, and RAG for working with educational materials
• Stripe — subscription and payment system

What can be implemented within the system:

— user profiles and storage of all chat history
— language levels A1–C1 with difficulty adaptation
— uploading lessons (video, vocabulary, grammar) through the admin panel
— exercises and tasks based on the material
— AI trainer for conversational practice
— gamification (XP, series, achievements)
— daily tasks
— subscription system via Stripe

It is also possible to implement the RAG model through pgvector, so that the bot uses your educational materials for responses, not just the general model.

If needed, I can:
• help design the architecture
• implement the MVP
• create a scalable structure for further product development.

We can discuss:
1. the expected number of users
2. the format of exercises
3. the structure of lessons and admin panel
4. timelines and stages of development. Expand

Hello!

My name is Alexey, and I represent the team at The Dev Company. Regarding your task with the language Telegram bot, the logic of a custom micro-SaaS with a backend and admin panel fits perfectly with the following stack:

- Telegram Bot API as the main user interface
- n8n for workflow automation and background scenarios
- OpenAI API for the AI trainer and generating/checking responses
- PostgreSQL as the main database
- pgvector for RAG (searching through lessons, vocabulary, user notes)
- Stripe for subscription payments
- Web admin panel for uploading lessons, vocabulary, and managing content

How it can work

The user interacts with the bot in Telegram, while the entire "brain" is on our backend: storing the profile, level (A1–C1), chat history, and progress. Through the admin panel, you add lessons (videos, vocabulary, grammar, exercises), set the structure of levels and courses. Content is indexed in pgvector so that the AI can pull relevant pieces during dialogue practice (RAG approach).

The AI trainer for conversation practice works through OpenAI: the bot conducts a dialogue in a native speaker style, relying on the student's level and the material covered, and suggests vocabulary/grammar when necessary. The entire chat history is saved, providing "full memory" and the possibility of adaptive learning.

Gamification: XP for lessons and exercises, streaks, achievements — everything is calculated on the backend and displayed in the bot. Daily tasks are generated automatically (via n8n) considering the level and progress.

Stripe handles subscriptions: payment → webhook → activation/renewal of access to paid features (lessons, AI practice, advanced analytics, etc.). The subscription status is stored in PostgreSQL and used when delivering content.

This stack provides flexibility, scalability, and the possibility to expand in the future: adding new exercise formats, additional languages, a web version of the user cabinet, and advanced learning analytics.
