Best alternatives to Privacy Mask in 2026
Pasting a screenshot into ChatGPT or Claude to ask 'what's wrong with this UI' or 'help me debug this' is a common habit — but that screenshot often has a phone number, an ID card, or a stray API key visible in it, and once it's sent, it's sent. Privacy Mask catches that before it happens: it scans a screenshot locally, finds anything sensitive, and blurs or blocks it out automatically. Privacy Mask is a free, open-source, MIT-licensed tool that detects over 40 categories of sensitive data — phone numbers, national ID card formats from 15+ countries, financial data, and API keys — using a combination of named-entity recognition and regex pattern matching, backed by dual OCR engines (Tesseract and RapidOCR) to read text embedded in images. Everything happens 100% locally and offline, so the original unredacted screenshot never has to leave your machine, and it integrates with 20+ AI coding platforms so it can sit in your existing workflow rather than requiring a separate manual step.
