A free AI content detector (no account)
last updated 7 june 2026
verifai is a free AI content detector that runs as a browser extension — no account, no upload, no monthly word limit. Click scan on any page and it flags suspected AI images and text in place with a confidence score, scanning on-device so nothing leaves your machine.
Most "free" AI detectors are really free tiers: a few hundred words, a daily cap, or a sign-up wall, with the real product behind a subscription. verifai takes a different approach — it's free while in development, runs in your browser, and scans the current page on demand rather than metering characters.
Because it runs on-device with no account, there's no server-side history of what you scanned. That privacy-by-default stance is the point: a free check shouldn't cost you your data.
What "free" actually means here
verifai's free check has no hidden meter:
- no account or sign-in required
- no word or character limit — it scans the whole page
- no upload — it reads what's already rendered
- covers both images and text
- on-device scanning with no server-side history
The honest trade-off
Free and private comes with a trade-off worth stating: verifai's MVP uses a transparent on-device heuristic rather than a heavyweight hosted model, so it's built for fast, in-context triage rather than forensic verdicts. The architecture supports a hosted detection model in production without changing the free, no-account experience.
frequently asked
Is verifai really free?
Yes — verifai is free while in development, with no account, no upload and no word limit. It scans the current page on demand, in your browser.
What's the catch with a free AI detector?
With most tools the catch is metered limits or your data being processed server-side. verifai avoids both by scanning on-device with no account; the honest trade-off is that its MVP score is heuristic, intended for triage rather than a forensic verdict.
