How to investigate suspected AI content
1Choose a file
Select or drop a supported file. Its type is identified automatically and the inspection starts immediately.
2Read the findings
The browser checks supported metadata structures locally. Review AI-related signals and personal metadata separately.
3Follow the evidence
Keep the original file and its source. Compare the findings with the creator’s explanation before deciding whether to trust or share it.
AI image detector: find clues inside the file
An AI-generated image may look like a real photograph. Check the original file for generator names, saved prompts and supported AI-related records. This AI image checker shows the file information it finds; it does not classify an image by appearance.
A scan is not an authenticity certificate. Metadata may be missing, modified or unrelated to AI generation. Unsupported, encrypted, signed or malformed files may be refused rather than reported as having no traces.

AI detector FAQ
How can I check if a file was AI-generated?
Choose or drop your file into the detector above. It checks for supported AI-related information saved inside the file and shows what it finds. Use those findings alongside the source and creation history of the content.
How do AI detection tools work?
AI detection tools look for different kinds of evidence. Some examine writing, images or sound for patterns; others check watermarks or information saved with a file. This tool checks supported file metadata, such as generator names and AI-related records. It does not score writing style or analyze pixels or sound for AI patterns.
How can I tell if an image is AI-generated?
Check the original image file for generator information or AI-related records, then look at where it came from. This detector can reveal supported metadata in an image. Unusual visual details can prompt a closer look, but appearance alone does not establish how an image was made.
Can I check a PDF or Word document for AI use?
You can inspect supported PDF and DOCX files for AI-related information saved in the document. This may reveal clues about the tools used to create or export it. It does not determine whether the text was written by ChatGPT or another AI writing tool.
How accurate are AI detectors?
Reliability depends on what a detector checks and which evidence is available. A tool that reads file information answers a different question from one that estimates AI use from writing or images. Review the specific findings and limitations before drawing a conclusion. A detection result alone should not be treated as proof of authorship.
Can AI-generated content go undetected?
Yes. A file may contain no supported AI-related information, or that information may have been lost during editing, export or sharing. A result with no traces found means this scan found no supported signals. It does not prove that the content was made by a person.
