I've 'shown' this a few times before but with minimal response, so I'm still looking for good feedback from the HN community. And since I seem to be asymptotically approaching the monetized 1.0 version I thought I'd try again.

BrainTool is a private- and local-first Chromium (no FF RN) extension that makes it easy to save tabs into a nested 'topic' hierarchy along with a note, and then use those topics to control the browser, opening and closing tabs as a group.

Plain text file (org mode) data storage, full keyboard support with search, TODO's and more. I just added local file syncing and some UX upgrades.

Thoughts?
