Small by design
Create Cornell notes, organize lecture outlines, extract recall questions, clean Markdown, and collect note photos in a PDF.
Privacy and saved work
These utilities run locally in your browser. Notes are saved automatically in this browser profile using localStorage. There is no account or automatic upload of notes. Clearing browser data removes local notes, and private browsing may discard them when closed. Export JSON backups regularly and test importing them in a separate profile. Other devices do not synchronize automatically. The hosting service receives ordinary page requests, including network information such as your IP address.
Working offline
The service worker caches app assets and visited pages after installation. Visit tools and guides while connected before relying on them offline. Test reopening the workspace without a connection. Browser storage eviction can remove cached pages and saved notes; keep exported backups outside the browser.
Editorial approach
Our guides explain practical workflows with examples and reusable templates. Outputs are starting points: check academic facts against your course materials. Calculators show estimates, not guarantees about grades or memory.
Accessibility
Use a keyboard to navigate fields and buttons. Text output can be copied into your preferred editor. PDF exports are visual worksheets; retain the text version when an accessible document is required.
