## Description

Organize all your bookmarks, web resources, notes and to-do's into a personal Topic hierarchy and control your browser with the BrainTool Topic Manager. Open and close browser tabs, windows and tab groups with a click, or navigate using powerful keyboard commands. Capture links, notes and tasks while in context on a web page. Allocate each of your Topics to its own window or tab group for a focused workspace.

Tame your browser tabs, focus your attention and never be afraid to close a tab again!

"Every Browser user should try this...Bring your bookmarks into the 21st century" - ZDNet

Your BrainTool data is private, it's your personal information space that the BrainTool application reads from a plain text file completely under your control. It's written in the popular Org-Mode format and so can fit within any larger text-based workflow. Back it up, copy it, share it - it's just a text file that you own.

Import from bookmarks, Org files or other extensions, sync automatically to Google Drive or a local file. BrainTool is 100% browser based, so your data never leaves your control.

BrainTool is hard to summarize. Its a way-better bookmarks manager, but it's also a browser manager, a tabs manager, a task manager, and a session manager.  It's a personal knowledge management system that allows you to organize all of your online information sources (web sites, Google docs, gmails, files, photos, Slack channels, social media groups, code repos, wiki pages, task backlogs, Jupyter notebooks, LLM chat sessions, etc etc etc), combine them with your TODO's and text-based notes and see the big picture in the tree structured side panel. It's the plain text bookmarking tool that I always wanted to exist but could never find, so I built it. I hope you like it!
