AI humanizer that flags AI writing tells
This AI humanizer checks your text against a list of phrases, punctuation and patterns that make writing sound machine-made, then highlights each one with a suggested fix. It flags overused AI words, em dashes, hedging, filler openers, likely passive voice and sentences over 25 words. It is deterministic and runs in your browser, so you stay the editor.

Why not just run another AI over it?
Rewriting with a second model often swaps one set of tells for another, and it can change meaning. A rule-based check shows you exactly what to change and why. You keep your facts and your voice.
What gets flagged
| Pattern | Example | Typical fix |
|---|---|---|
| Overused AI words | delve, leverage, robust, seamless | explore, use, strong, smooth |
| Filler openers | "It's worth noting that" | Delete it and state the point |
| Hedging | "may potentially", "arguably" | Commit, or give the condition |
| Em dashes | A long dash joining two clauses | Comma, colon or a new sentence |
| Passive voice | "was approved by the team" | "the team approved" |
| Long sentences | Over 25 words | Split into two |

Frequently asked questions
Will this make AI text undetectable?
That is not its goal. It points out patterns that make writing generic so you can edit them. Clear, specific writing is the aim.
Is my text uploaded?
No. The checks run in your browser with regular expressions. Nothing is sent to a server or a model.
Why flag em dashes?
Heavy em dash use has become a common tell in AI drafts. Commas, colons and shorter sentences usually read more naturally.
