Verification

Is this real?

Drop a photo or video. KolTheia reads every mark it can carry — a KolTheia seal, another maker's Content Credentials, a hidden watermark, the pictures of a photo or video — and tells you exactly what it found. No account needed.

Have a proof code? Look it up directly

With a file dropped above, the code is also used to tell you whether the file still matches it.

What KolTheia cannot check: Apple's "Reference Image" marking on an edited photo. Apple's own rules only let an app notice that mark and send you to Apple's own viewer to see what changed — they don't let any other product, KolTheia included, read or confirm it directly. Apple has said more detail is coming in 2027; until then this is simply outside what a file can be checked for here.
