ZeroNote
What ZeroNote is
ZeroNote is a free, self-hosted and web note workspace that combines notes, password records, bookmarks, document storage and two-factor authentication under smart tags. It works offline by keeping information in the browser’s IndexedDB, and the maker says it works on any device with a browser and can be installed as a PWA. Notes support Markdown rendering, code syntax highlighting, split-screen editing, searching across titles and content, file attachments, and references to YouTube, Instagram, Twitter and Reddit. Password tags hold structured credentials and associated domains, while TOTP tags generate timed codes. Notes are encrypted on the device with AES using a master password that never leaves the device, according to the maker; that password cannot be recovered. Optional synchronization uses direct WebRTC or S3-compatible storage such as AWS S3 and MinIO. Encrypted JSON backups include attachments. Soft-deleted notes can be restored before automatic purging after seven days. The repository says maintenance and support have stopped.

Verdict
ZeroNote combines several personal information tools in one browser workspace, with offline storage, encryption and optional synchronization. Its unrecoverable master password and discontinued maintenance should be considered before relying on it for important data.
