Derakus Language Tutor

Language Tutor is a voice-driven language learning app built for real conversation practice, not flashcard drills. Talk to it like you would talk to a friend — it talks back in a warm, natural voice and adapts to your level without ever sounding like a robot reading a textbook.

This one is personal. It was built so a certain someone could practice French (and any other language she wants to try) with a familiar voice on the other end. Every response is generated by a fine-tuned chat model running on our self-hosted inference server and spoken aloud by a custom TTS voice — no cloud AI services, no per-minute fees, no data leaving home.

What's inside

• Conversational practice in 15 languages: English, French, Spanish, German, Italian, Portuguese, Dutch, Polish, Japanese, Korean, Chinese, Arabic, Hindi, Russian, and Turkish
• CEFR level settings (A1 through C1) so vocabulary and grammar match where you actually are
• Full voice input and output — speak your reply, hear the answer
• One-tap translations and replay for any reply you didn't catch
• Storytelling mode for when you want a bedtime tale in your target language
• Clean chat UI that stays out of your way

Install the APK, pick your language, pick your level, and start talking.
