AI-powered website blocker that protects your focus with NLP and ChatGPT
Enter topical keywords such as "gaming" or "movie" and the extension blocks pages that match them, so you never have to curate a fixed domain blocklist.
Switch between Strict Mode, which uses faster NLP classification, and GPT Mode, which uses ChatGPT for greater accuracy on ambiguous pages.
Submit keywords one at a time, remove them individually with an ✗ control, or wipe the whole list with a single Remove All action.
The developer states you do not need a paid ChatGPT subscription to use the extension's ChatGPT-powered mode.
