What an AI image detector answers
A detector answers whether the file shows signals associated with AI generation. It does not tell you where the image came from or whether the caption is true.
What reverse image search answers
Reverse image search helps find earlier copies, different captions, source pages, and visually similar images. It may reveal that a real photo is old or used out of context.
When to use each
Use detection when the question is whether pixels may be synthetic. Use reverse image search when the question is where the image came from, whether it is reused, or whether the caption changed.
Why both are useful
A generated image may have no search history. A real photo may have a long history with a different event. Combining both checks reduces the chance of relying on the wrong clue.
Detector score and source history answer different questions. Treat them as complementary signals.
FAQ
Can reverse image search detect AI?
Not directly. It can show whether the image appears elsewhere, but it does not analyze generation signals.
Can a detector find the original source?
No. A detector reviews the uploaded file; it does not search the web for earlier copies.
