A deliberate workflow

You make the final call.

Suggestions help you find a place to start. Human review is required before you share the result.

  1. 01

    Open & find

    Open your PDFs, add a word list, and choose format rules for email addresses, phone numbers, and more.

  2. 02

    Review & approve

    Approve or reject every candidate. Add manual boxes wherever needed, and check pages that need a closer look.

  3. 03

    Export & keep a record

    Approved areas are painted over and affected pages are baked into images. Download a ZIP with PDFs, a review CSV, and a printable summary.

More than a black box

A copy to share.
A record to keep.

A residual check before export

The output is checked for approved text, unexpected matches from enabled rules and your word list, and leftover document features. A file that fails is excluded from the ZIP.

This checks extractable content and document structure; it does not inspect the pixels of an image or replace your visual review.

A readable decision trail

The CSV records decisions, locations, masked text, page checks, and residual results. The printable HTML summary records counts and export settings. File names appear in these records: check them for sensitive information.

Check it yourself

Local, where
you can see it.

PDFs, word lists, and results are processed in this tab. Only settings and license status are saved in browser storage.

  1. Load the app once.

    Wait for “Ready to work offline,” then turn off Wi-Fi. Open a synthetic PDF and try the workflow.

  2. Watch the Network tab.

    Open your browser’s developer tools, choose Network, clear the list, and process a synthetic PDF. Your document contents are not sent to a server.

  3. Know the license connection.

    Activation and periodic checks contact Lemon Squeezy with license details only. PDFs, word lists, and results are not included. An active license remains available offline.

Read before you redact

Know what needs your eyes.

No OCR or image detection

Scanned or textless pages have no automatic detection. Inspect them yourself, draw manual boxes, and mark them checked. Also inspect low-confidence text pages directly.

Image pages lose searchable text

A redacted page becomes an image: you cannot select or search its text. Pages with visible annotations or form fields are also baked. You can choose to flatten every page.

Bring your own word list

Add names and other free-form sensitive information to your word list. Format rules cover selected US and Canadian patterns, and may miss content or flag harmless matches.

Your review is essential

Inspect every page and the exported PDF before sharing. The tool does not establish legal suitability for your documents or your use case.
