Notesnook

Notesnook is a private, open-source note-taking application built on a zero-knowledge architecture. This ensures that your notes are end-to-end encrypted before they ever leave your device, making them completely inaccessible to anyone but you. Your data remains private and is never sold or tracked. Access and sync your notes securely across all your devices, including mobile, desktop, and web browsers.

Beyond fundamental privacy, Notesnook offers a powerful suite of features to organize your thoughts and work:

• A rich text editor with support for tables, task lists, code blocks, and Markdown.
• Bidirectional linking to connect related ideas and build a personal knowledge base.
• A secure Web Clipper to save articles and webpages without compromising privacy.
• Encrypted note sharing and password-protected vaults for your most sensitive information.
• Built-in reminders and task lists to keep you on track.

As a fully open-source project, you can verify its security and even self-host the sync server, giving you complete control over your data.
