Aqllify
AI-powered Uzbek language tutor: 50 structured A1 lessons, GPT-checked exercises, spaced repetition and gamification. Live with a landing page, mini app and Telegram bot.
Aqllify is a production language-learning product: it teaches Uzbek through 50 structured A1-level lessons — vocabulary, grammar and exercises generated and checked with GPT-4o-mini.
Learning science is built in, not bolted on: spaced repetition (SM-2 algorithm) schedules reviews, and gamification (streaks, XP, achievements) keeps retention up.
The product ships on three surfaces: a marketing landing (aqllify.com), a Telegram Mini App (app.aqllify.com) and a Telegram bot (@Aqllify_bot). Backend — FastAPI, frontend — React/TypeScript, bot — aiogram.
The interesting engineering part is the exercise pipeline: GPT not only generates content but evaluates free-form answers with structured feedback, which requires careful prompt design and validation so that grading stays consistent across thousands of variations.
