Proof a document is what it claims to be.
ARCUS checks a document layer by layer and returns one risk score, with the evidence behind it. Bank letters, passports, contracts, invoices: if a forged one has a cost, ARCUS shows you where it was changed.

Six layers checked. One score you can trace.
A forger can make a page look right. It is much harder to make every layer underneath agree. ARCUS reads each layer separately, then combines what it finds into a single 0–100 risk score. Pick a layer to see what it checks.
Where a document lands
ARCUS does not accept or reject anything. It gives a score, a tier and the evidence. Your analyst makes the call. Select a sample to see its verdict.

Three critical, two high, one medium. Spotting the right place is a guess. ARCUS traces each sign to its place on the page and to the check that caught it, so the verdict holds up when someone asks why.
See what the eye can't. Drag to compare.
Every scan opens in the Preview tab. Switch lens to see the same page the way ARCUS sees it, then drag the handle across to compare it with the original.
The page lies. The file doesn't.
Every file records when it was made and what made it. The Metadata tab reads those details and checks them against the page. Step through the timeline.

Every verdict keeps its own audit trail. The same file on the same version gives the same result.
One scan. Three stages.
Upload a file, set the analysis depth, and ARCUS does the rest. Choose an engine and a court mode, then run the pipeline on the Sample Bank letter.
Six dimensions. One verdict.
Each dimension covers its own set of checks. Select a dimension to see what it found on the Sample Bank letter.
Every check, in plain words.
The checks ARCUS runs across PDFs, images and identity documents. Filter by dimension.
Now run it yourself.
Below is the ARCUS platform, running in your browser. Pick a document, run a forensic scan, and work through the findings exactly as an analyst would. No sign-up, no sales call.
That's the full ARCUS workflow. Everything you just did is how your team would use it day to day, on your own documents.
