IsThisImageAI is an online AI image detector. Upload a JPG, PNG, WebP or HEIC image, or paste an image URL, and get a verdict, a confidence score and a plain-English reason. Results are an estimate, not final proof. The free plan gives 20 checks per month with no account. Paid plans from $3.99 per month add a region heatmap, batch checking, report export and an API.
AI-generated images are everywhere and hard to spot. I wanted a fast, free, no-sign-up way for anyone to check a photo and understand why it looks generated.
