IsThisImageAI

IsThisImageAI is an online AI image detector that estimates whether a picture was made by AI. You upload a JPG, PNG, WebP or HEIC image, or paste an image URL, and it scans the whole picture for signs of AI generation.

Every check returns a verdict and a confidence score, plus a plain-English reason, such as mismatched lighting, unusually smooth textures or missing camera metadata. The free plan needs no sign-up and doesn't ask for your email, and files are deleted after analysis.

The free plan includes 20 images a month with a verdict, confidence score and one key reason. Pro costs $3.99 a month for 150 images and adds batch checking, all reasons and a heatmap showing which areas look AI-generated. Max costs $9.99 a month for 1,000 images and adds report export. There is also an API plan at $29.99 a month for 12,000 calls, which returns the verdict and confidence as JSON.

The important limit is that no AI detector is perfect, and the site says so itself: treat the result as strong evidence, not final proof. Detectors can wrongly flag real photos, especially edited or heavily compressed ones, and can miss new image models. Don't accuse someone or make a serious decision based on the score alone; look for the original source of the image as well.

Good fit for journalists and social media users checking viral images, teachers and contest organisers reviewing entries, and shoppers or moderators checking suspicious product photos and profile pictures. Developers can use the API to add a check to their own moderation workflow.
