Your clients' files can't go to Adobe's cloud.
So the backlog never gets done.

100% on-device

Private by architecture, not by policy

Apple Vision and Foundation Models run on your Mac. No file ever touches a server — there isn't one. Turn off Wi-Fi and run a full batch; it works exactly the same.

  • No upload — your documents never leave the Mac
  • No account, no login, no sync
  • No tracking, no telemetry, no analytics
  • No network call for your files — ever

The only batch OCR a lawyer is allowed to use.

Smart Redact

Burn out PII for good

Auto-detects names, emails, phone numbers and IBANs, then truly burns them out of the page — not a black box you can copy the text out from underneath. Redaction that holds up.

Overnight batch

Thousands of scans, done by morning

Drop a folder of thousands of scans and close the lid. Every file is journaled as it completes, so sleep, power loss or a quit mid-run picks up exactly where it stopped — never reprocessing, never losing the queue.

Pro tools

Everything the job needs, in one pass

Verify signatures

Check whether a batch of contracts is signed and valid, with a SHA-256 audit trail.

Bates & stamps

Sequential Bates numbering plus CONFIDENTIEL / COPIE stamps across a whole exhibit set in one pass.

Auto-organize

Sorts output by type — invoices, IDs, contracts — into folders, on-device.

Factur-X ready

Embeds compliant Factur-X e-invoice XML for the French e-invoicing mandate.

Watch folders

Point at a folder once; anything dropped in is processed automatically.

Compression

Shrinks finished PDFs without wrecking legibility, so archives stay small.

Straight answers

The three things people ask

How do I know it isn't uploading my documents?

No account, no login, no sync, and no network requests for your docs. Turn off Wi-Fi and run a full batch — it works the same. Privacy is the architecture, not a policy.

Won't OCR on thousands of files crash halfway?

Every file is journaled as it completes. Sleep, power loss or quit and Millrace resumes from the last finished file. It never reprocesses and never loses the queue.

Pay once — does that mean abandoned, or features locked behind upgrades?

$49.99 buys everything today, forever — every Pro tool, no in-app purchases. A major new version is a separate paid upgrade you can choose to take; the app you bought keeps working regardless.
