A tutor that's always on the page
Not a chatbot in another window — it marks up the page you're already on.
Graded like a teacher
Green checks on the steps that hold, a red circle on the one that broke — right on the line you wrote it.
Writes the fix in ink
Ask for the whole thing and it writes the solution out by hand, directly beneath the question.
Exact graphs, not sketches
Computed from the function you actually wrote, not eyeballed. Drag it anywhere on the page.
And everything else the tutor can do
- Answers you hear
- Interrupt anytime
- Follow-up anytime
- Knows your other notes
- Spin it in 3D
- Keep it or scrap it
- Your rules
