Free AI image detector – spot AI images & deepfakes

FreeLive

PixelSniff is a free AI image detector that lets you upload a JPG, PNG, WebP or HEIC file (up to 50 MB) to see how likely it was generated by AI. The tool runs several detection engines that examine generation artifacts, noise patterns and metadata, then returns a combined AI likelihood score from 0 to 100 % with a clear verdict, heatmap and reasoning. It can identify images from popular generators such as Midjourney, DALL·E, Stable Diffusion, Flux, Gemini and also spot deepfakes, synthetic faces and partially AI‑retouched photos. No sign‑up is needed for up to five free basic checks a day; signing up provides 15 credits for a month and paid plans add deeper analysis, history across devices, API access and larger credit bundles.
