Checkobot is a web-based AI image detector from SpoofSense that checks whether a photo was generated or edited with AI. A user uploads an image or links to one, and the tool, called Checko, returns a verdict of AI or No AI detected, along with the detector that fired and a short reason in plain words.
The service covers AI generation, AI edits and face swaps, and it also reads signed Content Credentials that declare an image as AI. It is built for people who receive suspicious pictures and for teams in moderation, insurance, hiring and marketplaces who can call it through an API. It does not name which AI tool made an image.
Every image goes through up to two detectors. Whole-image analysis runs on every upload and looks for patterns that AI image generators and editors leave behind, whatever the picture shows. Face analysis, a dedicated face-forensics model, runs when there is a clear face. It studies the largest face, including the jaw, hairline and neck, where swaps tend to leave seams.
If either detector crosses its threshold, the verdict is AI and the result names the detector. Otherwise it reads No AI detected, which Checkobot says does not mean the photo is real. The site refuses images under 256 pixels on the short side, heavily compressed JPEGs and files over 20 MB, and a refusal does not use up a free check.
Each result includes a clear verdict, the detector that fired (face analysis, whole-image analysis or signed Content Credentials) and a one-sentence reason. Pro adds raw scores from both detectors, and API plans add the face box. Users can also make a shareable result card, created on their own device, with the photo and verdict, plus a result link.
Supported formats are JPEG, PNG, WebP, AVIF, GIF, BMP and TIFF, up to 20 MB. Every check records the model and rules version, and the API returns both. On privacy, free checks are processed in memory and discarded, while a SHA-256 fingerprint and the verdict are kept. Paid plans keep images in a private history that can be switched off.

The Free plan is $0 for 3 checks a day. Pro is $12 per month for 1,000 checks a month. API plans cost $49, $149 and $499 per month, and Enterprise pricing is custom.
Yes. You can run 3 checks a day with or without an account. Free checks are processed in memory and the image is not stored, though a fingerprint of the file and the verdict are kept.
No. It means neither detector found signs of AI at its threshold. Detectors miss some fakes, so Checkobot advises treating it as one signal alongside where the image came from.
No. It reports whether an image shows signs of AI generation or editing, not which tool produced it.
Yes. One REST call to POST /v1/check takes a file or URL and returns the verdict, fired detector, reason, both detector scores and the face box. Batches of up to 8 images per call are available on Growth and above.
It accepts JPEG, PNG, WebP, AVIF, GIF, BMP and TIFF files up to 20 MB. Images under 256 pixels on the short side and JPEGs compressed below roughly quality 50 are refused, and HEIC files must be exported as JPEG first.
Not yet. You can check a still frame taken from a video today. Audio, live video and liveness checks are outside its scope.
