Overview

BlurData is a macOS app that automatically finds and permanently removes sensitive information from PDFs, screenshots and images — driven by on-device AI, not manual selection.

A neural text-recognition model reads any screenshot or scanned page (even with no text layer), and a named-entity-recognition model identifies who and what is sensitive — names, people, organizations, places — in context, not from a static list.

Everything runs locally: documents never leave your Mac, which makes it a fit for legal, healthcare and finance work where files can't touch a cloud. It detects emails, names, addresses, phone numbers, dates, account numbers and more, with custom patterns (including Bates / reference-number series) and one-click community presets for common documents.

Review the detections, adjust anything, then export a permanently redacted file — sensitive content removed from the document itself, not hidden under a box.

Manual draw-a-box redaction covers anything a model can't read, like bank scanlines or signatures. 7-day free trial.
