PDF Masker vs Auto Redact AI

Protect your sensitive information before sharing files with others. PDF Masker is a powerful security tool that lets you search and black out specific keywords across your PDF documents automatically. Import any PDF directly from your device using the Share menu. Enter your target keywords, and the app instantly hides matching text so you can send your documents safely. You can choose to export your final file as a searchable text-based PDF or as an image-based PDF. The image-based option is perfect when you want to permanently erase underlying text data so it can never be copied or recovered. Key Features - Smart Bulk Redaction: Enter a keyword and automatically mask every single match across the entire document. - Multiple Keywords Support: Separate multiple terms using spaces or commas to clear different pieces of data at once. - 100 Item History Tracker: Saves up to 100 of your frequently used keywords so you can reapply them with a single tap. - Custom Redaction Colors: Change the color of your redaction blocks from classic blackout to white or any custom tone. - Flexible File Loading: Easily load files from your system file picker, in-app web browser, or straight from other apps via the Share extension. - 100 Percent Offline Security: All processing happens locally on your phone or tablet. Your private and confidential documents are never sent to external servers. - Clean and Fast User Interface: Designed to be clean, fast, and simple for everyone, with no complex setup required. Whether you are hiding account numbers, blurred names, personal addresses, or sensitive corporate contracts, PDF Masker helps you prevent data leaks on the go.

Auto Redact is a document scanner that protects your privacy by default. Scan a letter with your camera, import a photo, or open a PDF from Files — personal data is found and blacked out automatically, entirely on your device. Share the redacted version anywhere with a clear conscience: paste it into ChatGPT, Claude or Gemini to get help with a contract, send it to your landlord, your lawyer, or a support hotline — without handing over your identity. WHAT GETS DETECTED AUTOMATICALLY • Names and addresses • IBANs, account and credit card numbers • Phone numbers and email addresses • Dates of birth, social security and tax IDs • Reference numbers, license plates and more YOU HAVE THE FINAL SAY • Tap any black bar to reveal it — deadlines and amounts often need to stay • Tap any word to black it out yourself, or draw a box anywhere on the image • Pinch to zoom for precise control on dense documents • Toggle whole categories (all names, all dates) with one tap SCAN ANYTHING • Camera scanning with automatic edge detection and de-skew • Multi-page documents and PDFs (rendered on-device, page by page) • Import from Photos or the Files app • Paste plain text to redact it before sending EXPORT SAFELY • Share the redacted image, PDF, or text — only the redacted version ever leaves your phone • One-tap handoff to ChatGPT, Claude, Gemini, email or any app • Redacted documents saved in an encrypted library (AES-256, Face ID / PIN lock) PRIVACY IS THE ARCHITECTURE, NOT A SETTING Text recognition runs on your device. Redaction happens before anything is shared. There is no account, no cloud, no analytics, no tracking — we couldn't read your documents if we wanted to. The optional "Ask AI" feature sends redacted text only, using your own API key. Try the built-in sample letter to see the whole flow in 60 seconds.
