Flashcards from your notes, scheduled for just before you'd forget them.
Paste notes to draft question and cloze cards, edit them, then study with a spaced-repetition scheduler. Decks, tags, search, a review heatmap and TSV import and export are included.
The app itself, running inside this page. Anything you do here is saved in your browser.
Ask it to do things
Press Ctrl+K in the app (Cmd+K on a Mac) and describe what you want. The model chooses from the app's own functions, runs them in order and tells you what changed. Some examples:
| Make 15 cards on the causes of World War I | Writes the cards into a new deck. |
| Make my Spanish deck harder | Rewrites that deck's cards with tougher prompts. |
| Start reviewing whatever is due | Opens a study session with today's due cards. |
Instructions you save in the same box, such as "keep it short" or "I'm a beginner", are added to every AI request the app makes.
