A free and open source
tool to redact

File formats supported

You can redact WebVTT (.vtt), subtitle (.srt), plain text (.txt), markdown (.md), and Word (.docx) files.

Runs on your computer

All redaction happens locally on your computer. Your files and their contents are never sent to a server.

Free and open source

You can explore and check the code. Open for anyone to look on GitHub.

Why is redacting files important?

Safer usage of LLMs & AI tools

Way too often unredacted files & documents are uploaded to LLMs or other AI tools. This puts sensitive data at risk and potentially violates GDPR regulations.

Protect your sources

Leaked information puts your sources and investigation at risk. There have been documented cases of AI tools leaking information to unauthorized parties.

Protecting victims & vulnerable individuals

Anonymizing information can be essential when sharing documents with other individuals or involved parties.

What Ardi redacts

What isn’t detected

Company names aren’t redacted in the current app. There are no dedicated detectors for passwords, credit cards, IBANs, or government ID numbers. File metadata is also not removed.

We recommend removing metadata from your files before sharing them. You can use our metadata remover.

Always have a human review the output. Ardi Redact can make mistakes and miss sensitive information. There is no guarantee that it will work as intended or produce the results you expect.
