Frequently asked questions
How does the AI detector work?
Paste your text and press Check text. Write It runs it through an AI detection model that estimates how closely the wording matches patterns common in AI-generated writing, then shows one score from 0 to 100 percent with a plain label: low, some or high AI signal. It works as an AI checker for essays, discussion posts, emails and any other writing from 20 characters up to 15,000 characters at a time.
Is the AI detector free?
It is free to start. A free Write It account includes AI detector checks every day, and paid plans include more usage. You sign in with Google so your checks stay with your account, and the text you pasted is still in the box when you come back.
How accurate are AI detector scores?
No AI detector is fully accurate. A detector estimates whether text resembles model output, and it can misread both human writing and AI-assisted writing. Scores also differ between detectors and between versions of the same one, so a result here does not predict the result anywhere else. Treat the score as an estimate to review, not as proof of authorship or misconduct. Your drafts, notes and version history are what show how a piece of writing was made, so keep them.
