About BrainTool - Go Beyond Bookmarks
Tab Tamer, Bookmark Banisher, Task Tracker. Searcher, Finder, Saver. Level up your browser productivity workflow with BrainTool. Open Source, usable free, plain text notes, to-do management and more.
Your BrainTool data is private, it's your personal information space. Back it up, copy it, share it - it's just a text file that you own.
Tame your browser, focus your attention and never be afraid to close a tab again!
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.
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.
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 also helps you manage your browser tabs, tabgroups, windows, tasks and sessions. 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.
------- RELEASE NOTES --------
# BrainTool 1.3
Three major improvements:
- Drag and Drop from web pages into the topic tree. Drag individual links or selected text including multiple links and drop under a topic in the tree. With a single link any associated text is added as a note. When text contains multiple links all are added under the topic.
- ποΈ TRASH special topic. Deleted items are moved under Trash rather than immediately deleted from the tree.
- π BOOKMARKS BAR special topic. This topic is kept in sync with the items in your browser bookmarks bar. Changes made in the tree are updated to the browser and vice-versa.

Bookmarker now checks the backing store file for external changes before allowing a save.

# BrainTool 1.0!
Here is an overview of whats new.
## Manifest V3
This change is not of great interest to a BT user but is mandated by Google and required non-trivial code changes.
## Full Tab Group Support
Full synchronization between Topics and browser tabgroups. By default Topics are now shown as tabgroups in the browser. Tabs opened from BT open in a tabgroup labelled with the appropriate Topic. In the Topic Manager open links and Topics are highlighted with the tabgroups color. Changing the tabgroups color in the browser is reflected in the Topic Manager. Name changes and expand/collapse operations are also synced.
Additionally dragging a tab into a tabgroup will save that tab into the Topic in BT. Dragging a saved tab out of its tabgroup will remove it from BrainTool.
## Sticky Tabs
When 'Sticky Tabs' is enabled the relationship between a tab and an associated saved item in the Topic Manager is maintained when you click a link in the saved tab or during a server side redirection. This allows you to navigate around a saved site or app, or get redirected to a different url (for example to a log-in page) while staying in the context of the original saved BT Item.
## Topic Tree visuals
The expand/collapse buttons and the favicon displays have been restyled, and an empty topic is now visually distinct. These changes make the tree structure easier to see, in addition to improving the styling in general.
## Session saving and Bookmarker Updates
The BT Bookmarker now has the option to save a whole tabgroup. When saving a session, tab groups are saved as the corresponding BrainTool Topic. Any ungrouped tabs are put in a tabgroup named with a Window-N prefix and saved under a Topic with the same name in the Topic Manager. The Session itself is given a Session-date Topic name and saved under the Topic selected in the Bookmarker or the Scratch default Topic.
## Preferences for Dense, Hide Notes, Tooltips and Large Font
## New Introductory Screens
We've added a helpful BrainTool Buddy to give a gentle introduction to BT when it's initially inβ¦
