Getting answers is easy. Learning and remembering is harder.
Rae tracks your understanding concept by concept — what's solid, what's slipping — and opens each session on your weak spots. Memory recalls what you said; Rae models what you've actually learned.
Your chats become flashcards that resurface right before you'd forget — spaced repetition, automatically. Chatting isn't remembering.
Ask and you get the full answer, step by step. Then Rae quizzes you on it with hints — so you recall it yourself, not just nod along.
Rae flags what it's unsure of and shows its working — so a confident wrong answer never quietly derails your studying.
Every answer becomes something you keep — flashcards, notes, episodes.
Crisp math, code, diagrams and chemistry — not walls of plain text.
Type it, say it in a voice note, snap the stuck problem, or attach the file.
Your questions become flashcards that return right before you'd forget — 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 struggle with, turns your sessions into flashcards, schedules reviews so things actually stick, tracks your mastery, and teaches like a tutor: clear step-by-step answers, then quizzes with hints so it actually sticks.
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.
