Klaus is an Android app to help new and experienced coders learn high-demand programming languages and actually remember what they study. It is a chat-first tutor — you ask, you get real answers, examples, and little exercises tuned to how you learn best.
Under the hood, Klaus is powered by a fine-tuned Qwen 3 14B model running on our self-hosted inference server. No third-party API keys, no data leaving our box, no per-token fees — just a focused coding companion that is happy to explain a pointer in C, walk through a TypeScript generic, or drill you on Python comprehensions until they stick.
What's inside
- Conversational lessons across Python, JavaScript, TypeScript, Dart/Flutter, and more
- Hands-on code reviews and worked examples
- Spaced-repetition style follow-ups to lock knowledge in long-term memory
- Clean, phone-friendly chat UI — learn on the couch, on the train, wherever you have a minute
