What is PrivateNotes?
PrivateNotes is a secure note-taking web application designed for capturing and connecting ideas. It employs a graph-based organization system that links related notes into an interactive visual structure, moving away from traditional rigid folder hierarchies. This approach allows users to visualize connections between ideas dynamically.
The application ensures data security through zero-knowledge encryption using AES-GCM 256-bit with PBKDF2-SHA256 key derivation. All data is encrypted directly on the user's device before any storage occurs, maintaining privacy. It operates offline-first, works in any modern browser without installation, and offers features like a rich text editor with WYSIWYG or Markdown support, fast search, and instant auto-save.
