Philter vs PineThink Redact

Philter is open-source software for finding and redacting personally identifiable information and protected health information in text. For detected entities, users can choose to mask, encrypt, replace with synthetic values, remove, or pass them through. Policies, custom dictionaries, and identifier patterns such as medical record numbers and transaction IDs let teams configure what to detect and how to handle it. General Purpose, Healthcare, and COVID-19 NLP lenses address different types of text. Philter provides an HTTP REST API, a Java SDK, and an OpenAPI specification for generating clients in other languages. It can run in a private environment or through AWS, Google Cloud, and Microsoft Azure marketplaces. The maker says text stays in the customer’s environment, including firewalled or air-gapped deployments. Redaction requests are recorded in a tamper-evident, hash-chained audit log that can be queried and exported to CSV. Detection is probabilistic, so results should be checked against an organization’s own data before production use. The open-source toolkit has community support; commercial licenses include direct support.

PineThink Redact is a desktop app for finding and removing personal information from PDFs, Word documents, and scans. It detects names, addresses, phone numbers, SSNs, account and card numbers, dates of birth, and medical details, and supports custom terms. Users review detections before removal. Instead of placing a black cover over sensitive text, the app deletes it from the file’s content. Detection, review, and redaction take place on the user’s PC; documents are not uploaded. Built-in OCR reads scanned documents, including image-only PDFs. The free tier permits one document at a time for personal use and needs no account. Premium costs $6.99 a month after a free 14-day trial. It adds folder-based batch redaction, saved settings, custom term lists, per-file audit reports, commercial use, and AI agent access through MCP. The app requires internet for activation and periodic subscription checks, but works offline between checks. PineThink says anonymous usage statistics contain no file content and can be turned off in settings.
