Does my writing sound like AI?

Paste your text to see the exact phrases that make writing read as machine-made: stock transitions, filler, AI-favoured words, em dashes and monotonous rhythm. It checks phrasing, not who wrote it.

What it checks

Phrasing people and detectors notice

Each pattern links to a fuller explanation. None of them proves anything on its own; a cluster of them is what makes text read as generated.

Stock transition

Formal connectors at the start of a sentence are one of the most common things detectors and readers notice.

Filler phrase

Phrases that announce a point instead of making it add length without meaning.

AI-favoured word

Language models use these words far more often than people do, so a cluster of them stands out.

Em dash

One or two per page is normal; models use them in almost every paragraph.

“Not X, but Y” framing

Setting up a contrast nobody asked about is a signature of model-written prose.

Staged opener

Lines that build up to a point (“Here’s the thing”) read like a script rather than an explanation.

Even rhythm and repeated openers

Sentences of nearly the same length, or many starting with the same word, read as monotonous and are weighed by detectors.

Not checked on purpose: missing contractions and plain vocabulary. Both are correct English, and both are common when you write carefully in a second language.

FAQ

Questions about the checker

Is this an AI detector?

No. It doesn't guess who wrote the text. It points out specific phrasing that readers and AI detectors associate with machine writing, so you can decide what to change. A detector gives you a probability; this gives you the exact words.

Why doesn't it flag missing contractions or simple vocabulary?

Because those are correct. Academic English avoids contractions, and people writing in a second language often choose words they are sure of. Detectors do penalise both, but telling you to change correct writing would be bad advice, so the checker leaves them alone.

I wrote this myself and it still shows flags. Does that mean I'll be accused?

No. Plenty of people write “Moreover” or use em dashes; these are habits, not evidence. The checker helps you vary them if you want to. If you are worried about a detector, keep your drafts and version history: that is what actually shows authorship.

Is my text stored?

No. The check runs entirely in your browser; the text isn't sent to our server.

What should I do with the results?

Cut stock transitions you don't need, say filler phrases directly or drop them, replace inflated words with the plain word you'd use out loud, and mix short sentences with longer ones. If English is your second language, the editor can do this with you while keeping your meaning.
