The AI that thinks it through.
Several frontier models behind one chat. Fast answers when you want them, deep reasoning with OX when it matters, images, live web search, PDFs read properly — and flashcards and quizzes from anything you paste in.

Watch it work, live.
The models
Pick the brain for the job.
Switch mid-conversation. The chat keeps its memory; only the model changes.
Instant answers for everyday questions. Unmetered on paid plans.
FreeBetter writing, better reasoning, longer context. The daily driver.
One ProWorks through hard problems step by step before answering.
One ProThe deepest reasoning available — Claude Opus 5 behind it, plus Fable and the Agnes models.
One UltimateWhat it does
Built for people who study.
Flashcards and quizzes
Ask for them from any topic, lecture or PDF. Real quizzes — options, marking, a score — and a share link anyone can open, no account needed.
Reads your documents
PDFs, slides, scans. Scanned pages are OCR'd on our own server, so a photographed textbook page works too.
Live web search
On by default. It reads the live web before answering when the question needs it, and shows you where the answer came from.
Image generation
Say "draw…" and it paints. Every image is saved to your library.
Voice
Talk to it and have it read back. Useful with your hands full of a textbook.
Honest about what it is doing
While it works you see the real steps — reading your file, searching, reasoning — not a spinner and not made-up "thoughts".
Desktop
Chat. Cowork. Code.
The desktop app adds two things the browser cannot do: an agent that runs a goal for you, and a real code editor.
