About

BrainTool, founded in the United States, is a freemium and open-source tabs, sessions, and bookmark manager. It allows users to easily assign pages into a hierarchical set of topics and add notes. Users can then use these topics to open and close tabs and tab groups. Features include text search, keyboard control, and accessible plain text storage. It is available as a Google Chrome extension and as a SaaS. BrainTool offers features such as suggesting and voting on features, tab management, bookmarks, and plain text file support. The company maintains a presence on GitHub, Facebook, and Twitter. A user review highlights its source availability, accessible plain text, keyboard commands, any level of folder nesting, and incremental full-text search, positioning it as a great alternative to Tabs Outliner.
