Research
Explore original image metadata experiments with downloadable inputs, exact hashes and recorded outputs. See which creation records a file stores and what survives an export.
Open research
Every collection links its methods, input files and observations so you can inspect the result and repeat the check.
Inspect saved prompts, conflicting records, ComfyUI graphs and export behavior. Download the original PNGs, verify their hashes and reproduce the recorded output.
7 worked cases · 10 original filesControlled, code-drawn images with deliberately attached creation records.Download observations and hashes (JSON)Compare six operations across three constructed creation-record formats. Inspect field retention and exact pixel equality, then check your own original and exported files.
18 export testsVersioned local export tests; record formats describe the attached data, not the origin of the pixels.Download observations and hashes (JSON)Start with a supplied original, inspect the recorded fields and repeat the documented operation. Keep the file hash and software versions with your result. The examples test metadata reading and file transformations; they do not measure AI-detection accuracy or establish who made an image.
