- Enter important terms one by one
- Lose the visual context of diagrams and tables
- Preparation grows with every new document
Import your material and start studying
- Generate with AI, then adjust it yourself
- Keep the original textbook or worksheet layout
- Save, search, and review in one app

Frequently asked questions
What to know before you start
Start studying while your PDF is still processing
Import with the camera, photos, or a PDF and process pages in order. PDFs no longer have a fixed 20-page cap. Open ready pages, pause, resume, or retry an import. Free save slots, device storage, and document size still apply.
Two modes for different materials
Standard mode extracts key terms. The pre-marked-material mode uses existing red or orange text and highlighting in your material. It cannot recover text that is fully obscured in the original image.
Adjust masks in standard mode
Choose Low, Standard, High, or Before a test. Remove or add masks and switch patterns. Manual mask editing, density changes, and pattern switching are unavailable in pre-marked-material mode.
