A free browser extension that labels posts on X and LinkedIn that it considers likely AI-written.

Landing page captured for the 2026-09-26 issue.

For: People checking X and LinkedIn feeds for likely AI-written posts
Worth noticing: Checks only posts of 10 or more words, caps each install at 500 new posts daily, and says labels are signals, not proof.

Field notes

When a post of at least 10 words enters view, the extension sends its text and the hosting site for an AI-model check, then places a label in the feed. The page says post text is not stored and lists a daily ceiling of 500 checks per install; it also says a random install ID is collected. Firefox and Safari are unsupported, and the maker cautions that labels are signals rather than proof.
