The study app that
does the boring part.
Drop in your PDFs, videos and notes. It writes the study material, then tutors you on it.
Everything it makes
Five ways to learn the same thing.
Every card, question and answer is written from your notes, not the internet. Try them, they work.
Flashcards
Tap to flip. Say what you knew. Decks are levelled, so the basics come first.
How it works
Three steps, then it's just studying.
No setup, no prompts to write. The tutor reads what you give it and lays the work out.
Make a workspace
One per topic. Name it, or let the tutor name it from what you add.
Drop your materials in
Lecture PDFs, a YouTube link, a photo of the whiteboard, pasted notes. Each one is read, summarised and indexed.
Study, don't scroll
Read the brief, drill the cards, take the quiz, play the path. Ask the tutor whenever something doesn't land.
Step 2, up close
Summary
Limits and continuity
Defines the limit of a function and one-sided limits, then the three conditions for continuity at a point. Ends with the squeeze theorem and a worked sin(x)/x example.
Key points
- A two-sided limit exists only when both one-sided limits agree
- Continuity needs f(a) defined, the limit to exist, and the two to match
The flashcards, quiz and lessons below are written from notes like this one.
