Batch audit

Pro

Verify a whole delivery. Keep the receipt.

Drop in everything a vendor sent and get one table of results — plus a hashed report you can file against the contract. Because the question is rarely “is this one string marked,” it's “what did we actually receive, and can I prove I checked.”

Drop a set of files to audit them together

or

Images, PDFs, video, or audio. On the free plan the first 3 files of each batch are processed. Everything runs in your browser.

One pass, one table

Every file's verdict, signer, declared origin, and SHA-256 in a single view. No checking files one at a time.

A defensible record

Each row carries the file's hash, so the report ties to the exact bytes you checked. Export as CSV or a print-ready report.

Still private

Like every tool here, files are read in your browser and never uploaded. The audit report is generated locally too.

What Pro adds

The free plan audits three files per batch and generates reports. Pro removes the file limit, saves your audit history so cases persist between sessions, organises results by vendor and delivery, and — on Team — exposes the same verification through an API.
