Redactproof

Redactproof is a legal technology company that offers a browser-based document redaction platform designed for legal and compliance professionals handling sensitive disclosures, client files, and regulated data. The platform processes documents entirely on the user's device, ensuring that content remains confidential and is not transmitted to external servers. It supports PDFs, scanned documents, and image files, and produces exports that include audit trails, redaction summaries, and tamper-evident verification certificates signed with Ed25519 digital signatures. Redactproof is suitable for use cases including e-disclosure, subject access request (SAR) responses, and contract review workflows requiring a demonstrable chain of custody over redacted materials. A free tier is available, with paid plans for higher-volume workloads.
