AI Tab Group

AI Tab Group is a browser extension that uses AI to sort a user's open tabs into categorized groups automatically. Instead of manually organizing tabs, a user enters their own OpenAI API key in the extension's options page, and the extension analyzes tab content to cluster related tabs into named groups with a single click. It works in Chromium-based browsers, specifically listing support for Chrome and Edge. The free tier covers the core automatic categorization. A paid tier adds a hierarchical view that lists all categorized and uncategorized tab groups on one page, lets users close individual tabs or whole groups from that view, and allows saved groups to be exported as bookmarks or as a Markdown file. The tool is aimed at people who routinely accumulate large numbers of open tabs — researchers, developers, or anyone doing multi-topic browsing — and want an automated way to keep them organized rather than grouping tabs by hand. The clear limitation is that the extension depends on the user supplying their own OpenAI API key, so categorization is not free to run at scale and requires an existing OpenAI account with available credit.
