Features
One account, one place. The lesson, the practice, the plan, and the record of what you have actually learned. Every feature here ships today.
Every lesson is written out as you watch — titles, equations in real LaTeX, worked steps one line at a time, comparison tables, flowcharts, and graphs plotted to scale. You can wipe the board mid-lesson without ending the lesson.
Live voice is a real conversation: it explains out loud while writing on the board, and you interrupt it the way you'd interrupt a person — mid-sentence, not by waiting for a beep. It can search your notes while you're still talking.
When the thing you're stuck on is a real object — a titration setup, a leaf cross-section, a circuit, a map — it generates a properly labelled picture instead of approximating it with boxes and arrows.
It teaches from your lecture slides in your professor's notation, not a generic curriculum. Every card it writes from your files is stamped with the file and the page, slide, or timestamp — so you can check it.
In practice
Upload four weeks of lecture slides at 11pm and have it teach you the unit off your own deck, citing slide numbers you can check against the lecture.
“Wait — where did that 2 come from?” It highlights the exact line it came from and re-derives that step before carrying on.
Walk through a problem by talking. It explains aloud, writes the working on the board as it goes, and stops the moment you cut in.
Photograph a page of handwritten notes — badly-drawn arrows and all — and ask it to teach you what's on it.
Photograph the marked exam. Get a question-by-question breakdown of what went wrong in the working, then a fresh paper aimed at exactly those gaps.
Pick any of 182 languages and it teaches, quizzes, and marks entirely in it — the board written in your language, not translated after the fact.
