Notes worth keeping, kept sealed

Upload, share and collaborate on study notes across your school, college or university. Every note is encrypted on your device before it ever reaches our servers — only you and the people you trust hold the key.

Accounts are set up by your institution's admin — no public sign-up.

Sealed end-to-end

Notes are encrypted on your device with AES-256-GCM and RSA-2048. Servers only ever see ciphertext — and tampered data fails to decrypt instead of silently passing through.

Built for institutions

Notes are organized by school, college and university, and admins provision every account — so your notes stay inside the circle your institution set.

Real-time collaboration

Co-edit notes with classmates with live cursors, presence and in-app chat, all still wrapped in the same per-note encryption.
