Re-Doc (also written ReDoc) is a document anonymization and de-identification platform. It finds personal data in unstructured documents and replaces it with synthetic data, keeping the original layout.
Native PDF, DOCX and TXT files get synthetic replacement: names, dates, identifiers and addresses are swapped for realistic, consistent values, and the document keeps its format. Scanned pages and images get black-box redaction. Every result can be reviewed and edited before download. See document de-identification for how this relates to HIPAA Safe Harbor, GDPR anonymisation and pseudonymisation.
Re-Doc is built and operated by Cypherlayer Technologies Private Limited, a company incorporated in India. The product launched in 2026.
The first 10 pages are free in the web app, and an API is available on paid plans. For larger sets or custom deployment needs, contact our team. How we handle data is described in the privacy policy and the subprocessor list.
