I built a PDF redactor that auto-detects names, SSNs, and account numbers without sending your file anywhere - works on your phone too. Free, no sign-up. Plenty of redaction tools upload your file to their server first (no thanks for legal/medical/tax docs). Some keep the file local but send the text off to an AI, so the text still leaves.
