Gmail Thread Notes

Gmail Thread Notes lets you attach private sticky notes directly to your email threads — perfect for jotting down context, reminders, or follow-ups without cluttering your inbox or sending yourself another email.

Per-thread notes — Click the note icon next to any subject line to add a note. It reappears every time you open that thread.

6 color themes — Organize visually with yellow, blue, green, rose, lavender, or neutral notes, chosen per note.

Markdown formatting — Use bold, italic, and links in your notes, with handy keyboard shortcuts (Ctrl+B, Ctrl+I, Ctrl+K, Ctrl+Enter to save).

Quick copy-link — Copy a direct link to any thread with one click, great for sharing or referencing later.

Note manager — Click the toolbar icon to see every saved note at a glance, with subject and preview, and clean up any you no longer need.

Syncs across devices — Notes travel with your Google account via browser sync storage.

Dark mode support — Switch between light or dark theme.

Private by design — Notes are stored only in your own browser sync storage. Nothing is sent to any third-party server, and the extension requests no permissions beyond local/sync storage.

Whether you're triaging a busy inbox, tracking follow-ups, or leaving reminders for your future self, Gmail Thread Notes keeps that context right where you need it — attached to the conversation itself.
