How It Works

Three steps. Under a minute.

Drop a production document, review what's found, export with proof. No manual highlighting. No page-by-page hunting.

1

Drop your production document

Upload any PDF — discovery responses, deposition transcripts, medical records, financial statements. Auto-detection scans every page for SSNs, names, financial data, dates, and 15+ other entity types.

2

Review and redact

Every detected item is highlighted. Accept, reject, or manually label anything missed. Redact one instance of a name — all occurrences across the entire document update instantly.

3

Export with certificate

Download the redacted PDF with black bars burned in, metadata stripped, and a SHA-256 redaction certificate ready for your supervising attorney and case file.

Burn-in Redaction

The text is gone. Not hidden — destroyed.

Burn-in redaction removes the original text characters from the PDF, renders a solid black bar, and rasterises the page into a flat image. There is no hidden text layer left for opposing counsel to recover.

Select-all proof — highlighting and copying reveals nothing behind the black bar
Text extraction proof — PDF parsers and Adobe Preflight cannot recover redacted content
Metadata stripped — author, dates, revision history, and XMP data all removed
SHA-256 hash — cryptographic proof the output hasn't been modified after redaction

SSNs, names, dates of birth, financial accounts, emails, phone numbers, addresses, and 15+ entity types found automatically. No manual highlighting.

Redact once, update everywhere

Mark one instance of a name — every occurrence across the entire document updates instantly. No more hunting through a 200-page production.

Redaction certificate

Every export generates a certificate with session ID, SHA-256 hash, entity breakdown by type, and document integrity verification. Ready for your supervising attorney.

FAQ

Common questions from paralegals.

PromptSafe PDF produces burn-in redaction that permanently destroys underlying text — the same approach used by the DOJ and federal agencies. The output meets FRCP 5.2 requirements for redacting personal identifiers. Every export includes a SHA-256 certificate documenting what was redacted, ready for your case file.
Yes. Upload any PDF regardless of page count. Auto-detection scans every page, and redacting one instance of a name updates all occurrences across the entire document instantly. For multi-file production sets, process each PDF individually — the audit log tracks every document with session IDs and certificates.
PromptSafe PDF works with text-based PDFs — the kind generated by Word, e-filing systems, court reporters, and most modern document workflows. For scanned images without a text layer, you would need to OCR the document first using a tool like Adobe Acrobat before uploading.
Adobe Acrobat requires you to manually highlight each sensitive item on each page. PromptSafe PDF auto-detects sensitive data across every page and lets you redact all instances of a name or SSN with one click. It also generates a SHA-256 redaction certificate automatically — something Adobe does not provide.
Every export includes a redaction certificate with session ID, SHA-256 hash, entity breakdown by type, and timestamp. The certificate provides a clear audit trail your supervising attorney can review and include in the case file. The audit log also maintains a complete history of all redaction sessions.
Nothing leaves your device. The entire process — detection, redaction, and certificate generation — runs 100% in your browser. No files are uploaded to any server. You can verify this yourself in your browser's DevTools network tab. Attorney-client privilege is not compromised by third-party access, because there is no third-party access.
