isGenAI (isgenai.com) checks images, text, code and links for AI and shows the evidence: Content Credentials, AI labels and saved prompts. Free. No account. Private by default.
Upload an image, paste text or a link. The result shows here.
Quick answer
isGenAI (isgenai.com) is a free AI detector and AI identifier for files, images, text and code. Upload a file to check for AI, paste text or copy a link: it reads the evidence the content carries, such as C2PA Content Credentials, IPTC digital source type, saved prompts, generator metadata and AI-use statements, and names the source of every finding.

See how link checks workChecking a website for AI content starts with one exact public article or image URL. Paste it into the checker above and isGenAI reads the page text for AI-use disclosures and tool mentions, then inspects the main picture for supported creation records. Every finding is pinned to the page or file that supplied it, so you always know exactly what was checked.
A sentence saying “created with AI” is a disclosure. A reference to ChatGPT in an article about technology is a product mention. A signed image record is a separate, stronger kind of evidence. Open “How we checked” to see which source produced each finding and which checks completed. That is how you review a page with confidence, even when a copied or re-exported file has lost its labels.
The AI content checker lays out exactly which evidence you get for images, text, code and public links. It checks the public resource you submit, directly and precisely, rather than crawling a whole domain or breaking through logins, paywalls or CAPTCHAs. For text you already have, use the text and code checker; for a downloaded original, use the image checker or the AI file detector, which lists every AI record a file carries. The AI identifier brings image, text and file checks together on one page. Public links create public reports, so keep private material in the upload or pasted-text workflow and read the privacy policy for the details.

Seven worked cases built on ten code-drawn files show exactly how file records behave. Reproducible, hashed and open.

Read the checker methodology For developersDrop isGenAI checks into your app or workflow with one endpoint and a working Node.js example.
Run the API exampleYes. The isGenAI AI detector takes AVIF, PNG, JPEG and WebP uploads up to 20 MiB and reads every supported AI label, saved creation record and Content Credential inside, then explains each finding with its source. The report tells you exactly which records the file carries, so you know what the evidence covers.
Right here. isGenAI checks an image for AI with no account: drop a supported image into the checker, paste one from your clipboard or choose a file from your device, and the check starts instantly. Uploads are private by default and processed on isGenAI’s server. A clean copy is reported as a verified clean copy, never dressed up as a human certificate.
isGenAI does, on every result. The “How we checked” panel below each result shows the AI label, saved file detail or known matching copy behind a finding, together with every check that ran. Each source is labelled for what it is, because editable metadata, a signed record and a tool mention are different kinds of evidence, and you deserve to see which one you are holding.
Paste the public article URL into the isGenAI link checker. It reads the page’s accessible disclosures and the details of its main image, and keeps the source of each finding visible. It checks that exact resource, precisely, without crawling the whole site or bypassing logins and paywalls. Public-link checks create public reports, so keep sensitive URLs in a private workflow.
isGenAI.com is the free AI content checker that shows its evidence. Upload an image or paste text, code or a public link and it reads the saved creation records, supported Content Credentials and statements of AI use inside, then names the source of every finding so you can verify it yourself. A clean result means no AI record in that copy; it is evidence, not a guess.
You get a clear answer: “No AI evidence found”, verified from the file’s own records rather than a visual impression. Shared, screenshotted and re-exported copies lose their creation details, so for the complete picture check the original download too.
Your uploads and pasted text are private by default. We keep a record of the check, including file identifiers and findings, so you can retrace the result. Public links create public, shareable reports. Our privacy policy spells out exactly what is saved.
Yes. If the generator saved its prompt in the file, isGenAI reads it word for word, with the negative prompt, seed and model when they are present. A saved prompt is part of the file’s editable details, so the report shows you exactly which field it came from.
Yes. Paste your text or code and isGenAI finds every statement of AI use and every mention of OpenAI’s ChatGPT, Anthropic’s Claude, Google Gemini, DeepSeek and GitHub Copilot, and shows you the exact words it matched. These checks read declared use and tool names, not writing style, so the result is always traceable.
