158 USD AI agent for content automation in Threads
AI & Machine LearningSmall businesses (language schools, fitness clubs, salons, studios) need a stable presence on Threads, but managing it manually is expensive: coming up with topics daily, writing posts in a lively voice, maintaining a unified strategy, and avoiding "AI" templates. The owner doesn't have time for this, and delegating to an assistant is either costly or of poor quality.
Solution
I built a full-fledged content conveyor that prepares a stream of posts and sends them to the owner for quick approval in Telegram. The person remains in control: no post goes out without their "yes."
What the system can do:
…
Content strategy by pillars. Each post belongs to one of 5 directions (proof of result, benefit/learning, personal, offer, lead magnet) — the feed is diverse and well-thought-out, not chaotic. Frequencies and alternations are set up to avoid boring the audience.
Smart planning. The agent decides how many posts to publish and on which days, spaced out over time slots, without double postings.
Lively language, no "robotic" tone. Each text goes through several levels of checks: a separate reviewer-agent and a set of rules that catch calques, bureaucratic language, clichéd AI phrases, and clickbait. The output is natural Ukrainian that is not embarrassing to publish on behalf of the brand.
Approval in Telegram. Ready posts come to the owner in a bot — approve, reject, or send back for revision with one tap.
Metric tracking. The system reads post statistics from screenshots and keeps a history of results.
Weekly analytics. A clear report in human language: what worked, what didn’t, where to move the strategy.
Lead management. A separate module finds potential clients based on activity, qualifies them, and helps make contact.
Stack
Python, PostgreSQL, orchestration of background tasks, integration with LLM (Claude, Gemini) for text generation and verification, Telegram bot (aiogram) as a control panel for the owner.
Result
The owner spends a few minutes a day instead of hours — just approves the ready feed. Content is published regularly, maintains a unified style and strategy, and sounds human. The system is easy to adapt to any local business.

226 USD Telegram bot for online Spanish language school
AI & Machine LearningTelegram bot for an online Spanish language school — a full-fledged platform for teachers and students.
Website: https://espanola-lengua.com/
… Functionality for the teacher:
The teacher conducts lessons directly in Telegram. They can add words via text or voice (Spanish language recognition through Google Speech). After the lesson, with one click, they can create and send the student a vocabulary list with spoilers and a personal exercise package.
Exercise system:
10 types of exercises are implemented.
7 algorithmic: translation in both directions, choosing the correct translation, pairing, hangman.
3 AI exercises: fill in the missing word, guess the word from the description, form a sentence with inline buttons.
Adaptation for the student:
Levels CEFR A1–C2 are supported, which affect the difficulty of tasks, the number of options, and the mechanics of exercises. Support for 17 Spanish tenses (tiempos) and Participio is implemented with the option to choose via toggle buttons. The interface is bilingual — Ukrainian and Russian, each student sees the bot in their language.
AI integration:
Claude Agent SDK is used with model distribution by tasks: Haiku 4.5 for quick operations (e.g., vocabulary translation) and Sonnet 4.6 for generating exercises with grammar. Fallback between models is implemented for stable operation. A translation cache is added to the database to avoid repeated requests. Prompts are optimized for Spanish diacritics and specific symbols.
Sign-up for a trial lesson:
Leads from Instagram go directly into a form in the bot, choosing 1–3 convenient time slots. The teacher can accept, decline, or suggest another time. Time zone conversion is implemented considering DST. Applications automatically close after 48 hours. Protection against double booking is provided.
Web dashboard:
A separate interface for viewing metrics, student lists, and exercise statistics. There are progress bars, graphs of words per lesson, a dark theme, and auto-refresh every 30 seconds.
Production level:
Services operate via systemd with auto-restart. Daily database backups are configured. Monitoring with notifications in Telegram in case of failures is implemented. Secure SQLite migrations (ALTER TABLE) are used without data loss.
Integration:
The bot is integrated with the website through a floating transition button, sign-up form, and SEO markup (JSON-LD sameAs).
Technologies:
Python 3, python-telegram-bot, Claude Agent SDK, SQLite, ffmpeg, SpeechRecognition, systemd, nginx.
