The Slop Checker

Paste your text. We'll tell you if a robot wrote it — or if you just write like one. Your score is free; the full breakdown (every hit highlighted, every fix explained) unlocks with one email.

How it scores

Thirty known AI tells — delve, tapestry, furthermore, "in today's fast-paced…", em-dash confetti, metronome sentences — each weighted by how loudly it screams "autocomplete". Score is weighted hits per 100 words, graded A (human) to F (maximum slop). All in your browser. Your text never leaves this page.

Fair warning

It's a vibe check, not a courtroom. Good humans trip it; careful robots dodge it.
Short texts wobble. Under 30 words, take the score with salt.
The fix is always the same: say it like you'd say it out loud.
