TabMate

TabMate is a free Chrome extension built around one clear mission: solving the “too many tabs” problem with AI. Instead of you manually dragging tabs into groups, it looks at the content of the pages you have open and automatically sorts them into topic groups, so everything about a given subject ends up in one place. It is distributed on the Chrome Web Store and installs in a click.

Two features give you control over the automation. Smart Groups let you define custom topics that fine-tune how TabMate classifies pages, which is useful when you want a specific kind of page filed in a specific way. Locked Groups let you keep a hand-organised collection exactly where you put it, so the AI leaves it alone. The extension is also keyboard-first: most actions can be carried out without reaching for the mouse, which matters when you are sorting tabs quickly.

TabMate is openly labelled as experimental and currently in Beta, and the developer invites feedback and suggestions through the r/tabmate subreddit. That means you should expect an evolving tool rather than a finished product, and it is best suited to users who are comfortable shaping a young extension. It is free to use, and because it needs to read tab content, web history and activity to do its job, privacy-conscious users should review its data disclosure in the store listing.
