Nimbril
On-device PDF redaction that flattens marks to pixels, re-reads the export to report recoverable text, and issues a verifiable certificate
The product is on-device PDF redaction software for Mac that solves hidden-text failures by flattening approved marks to pixels and re-reading the exported file to report any still-recoverable strings, then issuing a signed certificate. It is for legal professionals and IT reviewers in businesses that handle filings subject to FRCP 5.2, HIPAA, FOIA and GDPR. It is positioned against desktop and cloud redaction tools that do not re-read their own output or provide a verifiable certificate, and runs fully offline with zero document bytes sent.
