What is Notesnook?

Notesnook is an open-source, end-to-end encrypted note-taking platform developed by Streetwriters. It allows users to create, organize, and synchronize notes across Windows, macOS, Linux, Android, iOS, and web browsers. Notes are encrypted client-side before transmission. The application includes a rich text editor supporting markdown, tables, checklists, code blocks, and math formulas. Additional functionality includes app locks, note vaults, note linking, a web clipper, note publishing, and an inbox API for external integrations. Users can also self-host their own synchronization server.

Key features

  • Cross-device synchronization that encrypts notes on the local device prior to transmission.

  • Rich text editing with support for markdown, tables, checklists, codeblocks, math formulas, and attachments.

  • Secondary password-protected vault to lock sensitive notes independently of general application access.

  • Web clipper extension to capture article text and images directly into notes for offline access.

  • Standalone web page publishing for individual notes with optional password protection.

  • Link notes together and view backlinks from other notes.

  • Set reminders on individual notes.

  • Lock the app with a fingerprint, PIN or password.

  • Create notes through an Inbox API using Zapier, IFTTT or custom scripts.

  • Import notes from other apps and common file formats locally on your device.
