A free GPTZero alternative for your browser

the verdict

GPTZero is a paste-and-check text detector popular in education; verif·ai is a free browser extension that scans the page you're already reading for both AI text and AI images and highlights them in place — they solve different problems, GPTZero for deliberate document verification, verif·ai for fast in-context triage while you browse.

If you want to check a specific document for AI writing — an essay, a submission — GPTZero is a purpose-built text detector with a free tier (around 10,000 words/month) and education features. If instead you want a quick, zero-friction read on whatever's in front of you as you browse, that's where verif·ai is different.

verif·ai isn't trying to win a text-accuracy benchmark. It's optimised for the everyday case: one click, on the current page, covering images as well as text, with nothing to paste and no account to create.

Which should you use?

Use GPTZero (or a dedicated SaaS detector) when you need a careful, documented verdict on a specific text — academic integrity, hiring, editorial sign-off. Use verif·ai when you're reading the web and want an immediate, calm signal on the page in front of you, images included.

verif·ai's text signal is a transparent on-device heuristic and images are flagged via embedded credentials, so treat it as triage, not a forensic ruling.

frequently asked

Is verif·ai as accurate as GPTZero?

Is there a free GPTZero alternative?
verif·ai is free and runs entirely in your browser with no account, making it a free, in-context alternative for everyday checks as you browse.
