One detection.
Every occurrence.
Instantly.

Before you can use AI with a 50-page contract, you need every instance of every name replaced consistently. PromptSafe handles that in one click.

When PromptSafe detects a name, email, or ID, it finds every instance in your document — headers, footers, signature blocks, everywhere.

Replace detected items across the entire document in one step. Same placeholder. Consistent results.

Three steps. Two minutes. Done.

Upload, review, download. It really is that simple.

1

Upload your PDF

Drag and drop any PDF. Contracts, agreements, letters — if it has text, we can anonymize it. Your file stays in your browser.

2

Review & refine

Automatic detection finds names, emails, phone numbers, and dates. Highlight text to add items, use search to find specific terms.

3

Upload to AI or share

Upload your anonymised PDF to ChatGPT or Claude for analysis. Or share the clean version with clients and counsel. Restore originals anytime with your key.

When you need more than text extraction

Some documents require visual review. PromptSafe PDF is built for them.

Multi-page contracts

50+ page agreements where names appear in headers, signature blocks, and body text. Navigate page by page and see exactly what's being anonymised.

Formatted reports

Medical records, financial statements, and audit reports where layout matters. Tables, columns, and structured data stay intact.

Documents for AI analysis

When you need to upload a PDF to ChatGPT or Claude but can't risk exposing client names, dates, or figures. Anonymise first, analyse safely.

Your documents never leave your browser

PromptSafe PDF runs entirely on your device. Share redacted docs with confidence.
