The free isGenAI detector
Check for AI. See the evidence.
Check my image for AI
Drop an image here or pick one from your device. The check starts the moment you choose a file.
PNG, JPEG, WebP, AVIF or single-page TIFF · Up to 20 MiBTIFF: full file evidence and eight pixel measurements, read straight from the original bytes, up to 40 million pixels.Every result shows exactly what we found and exactly how we checked it.
Read every available record.
Public AI-use statements, saved prompts, tool names, Content Credentials and file records, all pulled from the content itself.
See exactly how we checked.
Every report separates each finding from its source and lists which checks completed, so nothing is hidden behind a score.
Decide on evidence.
A clean copy is reported as a clean copy, and a statistical estimate is labelled as an estimate. You always know which kind of evidence you are holding.
The practical AI content checker
What does isGenAI check?
Start with the original file or the public source and isGenAI checks the copy you provide, then returns one report that separates saved metadata, signed history, public labels, matching copies and optional provider results.
Images
Read AI labels, saved prompts, generation settings, Content Credentials and matching copies. See the AI image checker for every supported format and limit.
Text and code
Find every statement that AI was used and every mention of ChatGPT, Claude, Gemini, DeepSeek or Copilot, with the exact words. Evidence you can point to, not a style guess.
Public links
Check any accessible article, post, website or image URL. When a platform blocks access, the report says so plainly instead of guessing.
Developer workflows
Use the AI detector API example to send one private input and get the same evidence-first result shape in your own app.
What does an AI content checker prove?
Exactly what it found in the supplied copy, from the checks that completed. It reports evidence of AI use with its source; it is not a certificate of authorship, factual truth or legal compliance, and it never pretends to recover records a re-export removed. Read the checker methodology for the full scope of each check.
Common questions
What is an AI content checker?
An AI content checker reads the content you supply for evidence of AI use: a public disclosure, saved file details, supported Content Credentials or a matching copy. isGenAI shows exactly which check produced each finding, so you get evidence you can retrace instead of a certainty score you have to trust.
What can isGenAI check?
isGenAI checks PNG, JPEG, WebP, AVIF and single-page TIFF images, public links, text and code. Images give up saved prompts, tool names, creation records and signed records; text and code checks find every disclosed AI-use statement and named tool, with the exact matching words.
Does a missing AI signal prove that content was made by a person?
No, and isGenAI is precise about that. A missing label, saved record or matching copy means the supplied version carries no such evidence. Screenshots, exports and reposts strip useful details, so the report keeps a clean copy clearly separate from a human-authorship claim.
