How a page is built
Not a chat. A page you can edit, transform, make your own.
Three building blocks. Shape every page the way you think.
02 · Editor
A real editor, not a chat.
Blocks, formatting, drag-to-reorder, slash menu. The keyboard does the work.
03 · The AI partner
An agent that writes into the page.
Highlight, ask, and the AI streams a researched section in. Cited, inline, editable.
Three kinds of return
How the page teaches you back.
One page, three ways it returns. On the day you'd otherwise forget.
You type the answer in plain English. The AI grades it like a teacher. FSRS books the next return on the day your retention is most likely to fall.
Share and learn together
Your page can be the start of someone else's.
Make a learning page public when you're proud of it. Start a new one from a page somebody else shared. Spaced repetition keeps either pulling you back.
