What's in the download
- The original images with SynthID intact: Google Nano Banana output in JPG, PNG and WebP. We capped the run at 50 images because synthid.com limits how many files you can upload per day and the SynthID Detector is web-only (manual upload, one file at a time, no API), so a larger run is a multi-day job
- SynthID-removed versions of the same images, paired by a 3-digit id
- synthid.com verdict screenshots for the removed images
- results.csv with 17 columns per image triplet, including every AI or Not verdict and confidence score
- README.md with the method, the exact verdict strings, the caveats and a per-image table
Who this is for
- Newsrooms and fact-checkers who want to check the pairs and the verdict screenshots themselves
- Trust and safety and platform compliance teams working under California's AI Transparency Act (SB 1000) and its disclosure verification tool requirement
- Insurers, KYC and fraud teams who need to know what a watermark check does and does not tell them about a submitted image
