Hi! Suggesting a tool for the Image/Video category.
Tool: bildesjekk.no — https://bildesjekk.no
Cost: Free, no account or sign-up required
Language: Norwegian (interface and results)
What it does
A browser-based image checker aimed at ordinary users dealing with
marketplace fraud, dating scams and AI-generated images. It runs, in
priority order:
- C2PA / Content Credentials — manifest validated cryptographically
against the official C2PA trust list
- EXIF / IPTC metadata parsing, including the IPTC "AI-edited" field
- A local ONNX pixel model (Community Forensics, MIT) running
client-side in the browser via onnxruntime-web
- A vision-model pass for visual observations
- An optional second-opinion check from an independent detector
Why it might be of interest
- Results are presented as separate lines of evidence in a signal
table, never as a single verdict. The tool never claims an image is
"proven authentic" and does not output calibrated percentages.
- It is deliberately tuned so that false accusations against genuine
photos weigh more heavily than missed detections, since the pixel
detectors disagree with each other often enough that neither can
carry a verdict alone.
- Uploaded images are not stored.
- Norwegian-language coverage in this category seems thin, and the
target audience is non-technical users rather than newsrooms.
Known limitations (stated openly on the site)
- It cannot tell whether an image is old or new — there is no reliable
signal for capture date in a re-saved file.
- Screenshots and re-compression destroy the pixel signals: JPEG
re-encoding at q75 collapsed detection on one test image from 99.9%
to roughly 4%.
- Absence of signals is not evidence of authenticity, and the site
says so directly.
I'm the developer, so treat this as a self-suggestion — happy to
answer questions or provide test images. Thanks for maintaining the
toolkit!
