Tamemono от Andrew Nguyen

Tamemono (溜め物 - "things that accumulate") is a note-taking extension that lives in your browser's side panel, so you can write while you browse without switching tabs.

Everything is local-first: your notes are saved in your browser and never sent to any server. No account, no login, no tracking.

Features
• Rich-text editor - headings, lists, task lists, quotes, tables, code blocks with syntax highlighting, highlights, and inline formatting.
• Folders, tags, and pinning to organize notes.
• Images embedded directly in notes.
• Full-text search across all notes.
• [[Wiki-style links]] between notes, with automatic backlinks.
• Web clipper - select text on any page, right-click "Save to Tamemono", and it lands in a note tied to the source page.
• Automatic source capture - notes remember the page you were on.
• Export / import your whole library as JSON for backup.

Your data stays on your device. Use Export JSON regularly to keep your own backups - this version does not include cloud sync.
