Concentration

AI-powered website blocker that protects your focus with NLP and ChatGPT

Keyword-based blocking

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.

NLP vs ChatGPT modes

Switch between Strict Mode, which uses faster NLP classification, and GPT Mode, which uses ChatGPT for greater accuracy on ambiguous pages.

Simple keyword management

Submit keywords one at a time, remove them individually with an ✗ control, or wipe the whole list with a single Remove All action.

No paid AI plan required

The developer states you do not need a paid ChatGPT subscription to use the extension's ChatGPT-powered mode.
