Checking an image made or edited with Gemini
Upload the best-quality file you have. SUREvAI can inspect available file history and visual clues, but it cannot directly read Google's private SynthID watermark.
Use the right evidence for the right question
A verified creation record can support a claim about how a specific file was made. Visual analysis can flag patterns that resemble AI images. Neither can prove every image's full history.
For Google's SynthID watermark, use an official Google verification experience where available. A negative watermark result would not rule out images from other generators.
Edits are particularly difficult
An AI edit may change only a small area of a camera photo. A whole-image score can miss such edits, and an innocent edit or filter can change visual statistics too.
Practical checking steps
Keep the original file. Compare it with the claimed source and any earlier version. Treat SUREvAI's Not Sure result as an unresolved question.
