How it works

Drop a file. Get it back clean.

Everything runs by itself: names are replaced, everything else is cleared. You see every spot before you download.

It finds the personal data

Your saved terms, the code rules and a local model on this Mac read every page. Text in images is read by OCR.

  • Names, addresses, phones, emails, IBANs, birth dates
  • Photos, scans and images inside PDFs and Word files

Check and download

Names are replaced, the rest is cleared, and the result is checked again by OCR: nothing personal is readable in it. Review or change anything in Detailed, then download.

Questions

Good to know

Is anything uploaded?
No. redact4AI runs on this Mac only: nothing is logged and files stay in memory until you drop new ones or quit. The activity list keeps only steps, times and counts, no names or text.
Which files can I drop?
PDF (scans too), Word, Markdown and text, and PNG, JPG, HEIC and TIFF images. Drop single files or a whole folder; subfolders are included.
What happens to the names?
Each person gets a made-up name of the same gender, or becomes its role in the document, e.g. Party 1, Patient. One person keeps one role. Everything else personal is cleared.
How do I know nothing was missed?
The result is checked again with OCR. In Detailed you see every spot, marked Sure, Likely or Not sure, and you can add a term or draw a box over anything; the box wins and everything inside it is wiped.
Can I save my own terms?
Yes. Save them as one terms file, encrypted with a password of at least 8 characters. The password is never written down or sent anywhere. It goes to your Downloads as pdf-redact-terms.enc. Next time: add the terms file, then the password.
What if I forget the password of my terms file?
Then the saved terms are lost. Nobody can open them, not even redact4AI.

It’s local. It’s fast. It’s yours.

redact4AI runs entirely on your Mac, so your sensitive data
stays where it belongs — with you.
