How it works
Three steps from notes to mastery
- Step 1
Drop your study material
Paste lecture notes, upload a PDF, or build a deck by hand. Claude extracts the testable facts into editable cards.
- Step 2
Study with spaced repetition
SM-2 schedules each card based on how well you know it. Just rate Again / Hard / Good / Easy and the queue handles the rest.
- Step 3
Track what sticks
Mastery rings, heatmaps, and a trouble-cards list show you exactly what's working and what needs another pass.
