# Redact documents in your browser

Redact PDFs, scans, photos, Word, Excel, PowerPoint, OpenDocument, email and text inside your browser, with a signed certificate for every export.

Redact documents in your browser. Nothing leaves it.

What it does today:
- Redact PDF, scans, photographs, Word, Excel, PowerPoint, OpenDocument, email and text
- 205 detectors for numbers, addresses, keys and identifiers
- The file is opened, read and rewritten inside your own browser, and never uploaded
- Scanned pages and photographs are read as pictures before they are searched
- A signed certificate with every export, which anyone can check without an account
- A report you can share behind a password and an expiry
- Names in English text and on scanned pages, as suggestions a person confirms
- Members, roles, shared templates and an approval before an export

Questions people ask first:
- Does the document really never leave my browser?
  Yes. Your browser can show you every request a page makes, and this one makes none while it works.
- What happens to the words under a black box?
  The page is rebuilt as a picture and the text behind the box is dropped, so copying, searching and extracting all come back with nothing.
- What is the certificate for?
  It is a signed record of which file went in, which came out and when, and anyone can check it at the address printed on it without an account.
- Do you find names?
  Yes, in English text and on scanned pages, as suggestions you confirm before they are redacted.
- Can I use it without paying?
  Yes: three certified exports a month, every format, every detector, up to 25 pages a document.
- What do you keep about my documents?
  A fingerprint of the file before and after, the page count and the number of marks, never the file, its name or anything found inside it.
