How to tell if text was written by AI (on the page you're reading)

the short answer

To tell if text was written by AI with verifai, open the extension on the page and hit scan; it puts a soft tint behind passages it judges likely AI-written and gives each a 0–100 confidence score, on-device and without an account.

The early giveaways of AI writing — robotic phrasing, endless 'in conclusion', the same three transition words — have largely been edited out. Plenty of AI text now reads like a competent human wrote it, which makes a gut call unreliable.

So instead of guessing from style, you can have the passage checked where it sits. Here's how to check the text on a page with verifai and how to interpret what it highlights.

Why style-spotting fails now

People look for tells: overly even sentence length, hedging, generic structure. Those heuristics worked on raw model output, but a light human edit erases most of them, and they also produce false alarms — plenty of careful human writing is even and well-structured too.

A detector looks at statistical properties of the text rather than vibes, which is more consistent than style-spotting. It still isn't certain, but it doesn't get fooled by a confident tone or thrown off by clean prose.

Reading verifai's text result

verifai puts a soft tint behind passages it judges likely AI-written and gives each a 0–100 confidence score with a high / medium / low level. Because the tint is on the text itself, you can see which parts of an article are flagged and which read as human, rather than getting a single verdict for the whole page.

Treat a high score as a strong reason to dig deeper and a low or medium one as inconclusive. The point is a calibrated read on what to trust, not a stamp of real or fake.

    read the tint

    Likely AI passages get a soft tint and a 0–100 confidence score.

frequently asked

Does verifai check the whole page or one passage?
It scans the text on the page and tints the passages it judges likely AI-written, so you see which parts are flagged rather than a single overall verdict.
Can it be fooled by edited AI text?
Editing makes any detector less certain, which is why verifai reports a confidence score and level instead of a yes/no. Use it as a signal, not proof.
Is my reading sent to a server?
No. verifai runs on-device in your browser, with no sign-in and no server-side history of what you scan.
What's a high/medium/low level?
It's a plain-language band for the 0–100 score, so you can act on 'high confidence' without parsing the exact number.
