Free AI detector for résumés and cover letters

See how much of your writing reads as model output, and what to change.

Paste any text, or drop in a résumé, and get a percentage for how strongly it reads as default AI writing, along with the exact words and sentence habits that gave it away. Rule-based and offline: no model is called, so nothing you write is sent anywhere.

What it does

• Evidence, not a verdictEvery signal carries the snippets that triggered it: the vocabulary that spiked after 2022, stock phrases, tricolons, negative parallelism, participial tails, uniform sentence length and em-dash habits.
• Word-by-word replacementsFlagged words come with plainer alternatives. Delve becomes look into, leverage becomes use, robust becomes reliable, and the sentence stops announcing itself.
• Human markers count tooContractions, specifics, numbers and irregular rhythm push the score down. The check measures what is missing as well as what is present.
• Model fingerprintsSome phrasings belong to particular model families. Where a fingerprint is strong enough to be worth naming, it is named, with the lines that carry it.
• Runs offlineThe whole check is a rule set, not an API call. It works with no network, no key and no account, and your text is never transmitted.

How to use it

1. 01Open the free check and drop in a résumé, or paste any text you want to test.
2. 02Read the AI meter: low is good here. Above 65 means the writing reads as generated.
3. 03Open the flagged lines and swap the marked words for the plain alternatives offered.
4. 04Rewrite the sentences that all have the same length; irregular rhythm is the strongest human signal.
5. 05Check again. The score should fall as the specifics go up.

Questions

Can an AI detector be trusted?

No detector can prove authorship, and this one does not claim to. It measures how closely a text matches documented model habits, and it shows you every reason for the number so you can judge it yourself.

Will a human-written résumé score high?

It can. Résumés are formulaic by nature: parallel bullets, no contractions, action verbs throughout. Read the signals rather than the number alone, and treat the flagged lines as writing advice.

Is my text sent to a model?

Never. The check is a rule set running in your browser. There is no API call, so there is nothing to intercept and nothing stored.

Does it work on cover letters and emails?

Yes. Text can be checked as a résumé, an email or general prose, and each mode weighs the signals differently because the norms differ.
