BrainTool is a Chrome extension that can be used as a unique bookmarks/tabs manager but which also synchronizes with a plain text emacs org-mode style file on your Google Drive to become a more all encompassing personal knowledge management tool.
The BrainTool panel in Chrome uses the org-mode tree structure but concentrates on the links within your notes thus unifying two primary ways to capture information.
Currently it works for my workflow and is at a general MVP level of functionality. It is published to the Chrome Extension store but unlisted. I’d love comments from a handful of early adopters.
