Tab Notes

A note-taking extension that replaces the new tab page. Quickly jot down ideas every time you open a new tab.

Turn every new tab into a distraction-free writing space. Tab Notes replaces your new tab page with a fast, beautiful markdown editor so you can capture ideas, write documentation, or keep running notes — right where you already are. Why Tab Notes? Most note-taking apps live behind a login, inside a separate window, or buried in a tab you forget about. Tab Notes puts your notes front and center every time you open a new tab. No accounts. No cloud. No distractions. Just you and your thoughts.
