How it works
Inside a Raitu session.
One topic in, or your own notes. Watch the whole loop: plan, teach, check, interrupt, quiz, replay.
Step 1
Ask a topic
Type it or say it: “How do rainbows form?” Raitu turns it into a session plan: sections, figures, and check-in points, ready in seconds.
Step 2
Or hand over your own material
Snap a photo of tonight's homework, or upload a PDF of past papers or class notes. Raitu reads it once, then teaches it as a session, quiz and all. The file itself is discarded after it is read.
Step 3
Raitu plans the session
AI is what makes this possible. Every session is planned in seconds and structured: an opening, clear steps, and moments where the tutor pauses to make sure you're following.
Step 4
It draws as it teaches
The tutor narrates while figures and graphs are drawn live. A curve takes shape as it explains what the slope means. Seeing and hearing the same idea at the same time is what makes it stick.
Step 5
Check-ins
At good stopping points Raitu asks a quick question. Right answers move on; wrong ones get the idea re-taught a different way.
Step 6
You interrupt
If you don't follow, just ask. It stops, answers, then continues where it stopped.
Step 7
Prove it
The session ends with a scorecard: how you did across its check-ins, and the ideas worth revisiting. Pass, and you can take a full-session quiz: new questions covering the whole topic, graded instantly, with a per-question review.
Step 8
Replay anything
Every session is saved. Scrub back, re-hear a step, re-see a figure. Your session history is in the sidebar whenever you want it.
Mid-session, you stay in control.
- Pause & resume
- Mute the voice
- Switch tutor voices
- Scrub the progress bar
- Request a re-explanation
- Start a new session
- Replay from history
- Ask questions out loud
How Raitu is different
Not a chatbot. Not a video. A tutor.
Chatbots
ChatGPT, Claude, Gemini, etc.
A wall of text you read. No voice, no drawings, no session plan, and it never checks you understood.
Videos
They talk, but at their pace. They can't hear your question, can't stop, can't re-explain it differently, and they have no idea what your notes say.
Raitu
Teaches out loud, sketching diagrams and equations as it explains. Stops when you ask a question. Re-explains differently when you're stuck. Checks you've got it before moving on. And it teaches from your own material: upload your notes, a past paper, or a photo of your homework.
