ChatGPT hands you the answer and forgets it. Rae is a personal AI tutor that works with you until you've mastered it.
Every answer becomes something you keep, like a quiz, a note, or a podcast episode.
Crisp math, code, diagrams and chemistry, not walls of plain text.
Type it, say it in a voice note, take a photo of the problem, or attach the file.
Your questions come back exactly when you need them, with a nudge only when something's due.
Every explanation saved as a clean, searchable note, organised by subject.
Pick a topic and a voice. Rae records a ~10-minute episode from what you've been studying, and it evolves as you learn.
Rae lives inside Telegram, so it just works on your phone and the desktop app. One account; your chats, notes and progress stay in sync across both.

ChatGPT answers a question and forgets it. Rae is a study system: it remembers what you're working on, turns your sessions into quizzes, and brings them back to keep them fresh. You get clear, step-by-step answers with a hint whenever you want one, and it tracks what you've mastered as you go.
Rae is built to be honest: it flags when it's unsure, separates settled fact from interpretation, and shows its working so you can follow along. Spot an answer that looks off? One tap runs an independent check and corrects it in place.
Yes. Rae adapts its language and tone to your age, keeps everything age-appropriate, and declines anything unsafe. It's a calm, supportive tutor, with no manipulative streaks or engagement tricks, because we optimise for you learning and getting on with your day.
Just about anything you study: maths, the sciences, coding, languages, the humanities and beyond. Math, chemistry, code and diagrams all show up cleanly, never as walls of plain text.
