Check origin answers one question about a picture or a video you attach: does it look authentic, or does it carry the marks of generation or manipulation? It is an explicit ask on attached media — not something that runs silently on every image in a thread.

​
Run a check

1

Attach the media

Choose + → Check origin on the composer, or attach the file with Attach file. iPhone HEIC/HEIF photos are accepted.
2

Ask

Is this photo authentic? or Was this generated? The turn runs the origin check on the attachment.
3

Wait for the verdict

Cortex holds its reply until a verdict paints. You will not get a confident paragraph followed by a result that contradicts it.

​
When the check cannot run

If origin check is unavailable on a deployment, the product says so instead of guessing. That is fail-closed behaviour, not a broken button: no verdict is still no verdict. Ask again later rather than reading silence as a result.

​
What it is not

Pictures generated with Cortex-Image-1 are ordinary Library files. If you want to know whether one of them reads as generated, attach it and ask — the check does not run on its own after generation.
