Our verdict
PixelSniff says it is a free AI image detector: upload or paste an image and it returns a 0-100% 'AI likelihood' score with a verdict. Its changelog says the free basic scan is powered by Illuminarty, and an opt-in Deep Scan (sign-up and credits needed) adds TruthScan, with the combined score weighted 60% TruthScan and 40% Illuminarty. So the 'multiple detection engines' are two third-party services, and a guest's free basic check shows a single engine score. In our test, a simple drawing we made with Python (shapes and text, no AI) scored 25% AI with the verdict 'most likely not AI-generated', and returned the result without needing an account. PixelSniff's own terms say it does not publish or guarantee an accuracy rate and that results will include false positives and false negatives. Independent tests of detectors like these have found misses and false alarms. Use it as one quick signal alongside provenance checks, never as proof about a person or a piece of evidence.
You want a free, quick second opinion on whether an image you found online looks AI-generated, and you will check its source too.
You need a result you can rely on for a decision about a person, an insurance or fraud claim, journalism or legal evidence, or you cannot upload the image to an unidentified operator and its third-party detection providers.
Pricing: As of 20 Oct 2026: Free: 5 basic checks a day with no account, plus 15 credits on sign-up (valid 1 month), per the pricing page; the changelog's launch notes say 10 guest scans a day and 10 sign-up credits, so the figures on the site are inconsistent. Pro $19.90/month or $199/year (2,000 credits a month). Credit packs for Pro subscribers: 5,000 credits for $49 or 10,000 for $99 (never expire). Enterprise custom (API access, invoiced billing). A basic check costs 1 credit and a deep analysis 5 credits. Subscriptions renew automatically until cancelled; a failed analysis refunds credits, not money. Checkout code references Stripe.
