Frequently asked questions
Is this AI detector free?
Yes. AIScan Lens is completely free with no sign-up and no daily limit. The site is supported by advertising.
Are my files uploaded to a server?
No. The analysis runs entirely inside your browser using JavaScript. Your image, video or text is never sent to us or stored anywhere.
How does the AI image detector work?
It reads provenance metadata embedded in the file: C2PA Content Credentials, the IPTC "trainedAlgorithmicMedia" tag, Stable Diffusion and ComfyUI generation parameters, and EXIF/XMP software fields. When a generator such as DALL·E, Adobe Firefly, Midjourney or Stable Diffusion left a signature, the tool names it.
Which AI generators can it identify?
Any tool that writes identifiable metadata, including OpenAI DALL·E and ChatGPT images, Adobe Firefly, Microsoft Designer / Bing Image Creator, Stable Diffusion (Automatic1111, Forge, ComfyUI), FLUX, NovelAI, Midjourney, Google Imagen / Gemini, Leonardo.Ai, Ideogram, Runway, Sora and others.
Why does it say "No AI signature found" for an AI image?
Metadata is easily removed. Screenshots, social media uploads, messaging apps and many editors strip it. "No signature found" means the file carries no proof either way. It does not mean the image is real.
How accurate is the AI text detector?
Text detection is an estimate based on writing patterns such as sentence-length variation, vocabulary diversity and phrases common in LLM output. No text detector is fully reliable; edited AI text and formulaic human writing can both be misclassified. Use the score as one signal, never as sole proof.
Can I use the result to accuse a student or employee of using AI?
No result from any AI detector should be the only basis for an accusation. Metadata findings are strong evidence when present, but text scores are probabilistic. Talk to the person and look at drafts, history and other context.
What file types are supported?
JPG, PNG, WebP, AVIF, HEIC images, MP4 and other video files (for Content Credentials), and plain text (.txt, .md) or pasted text. Files up to 50 MB.
