Claude— THE PROBLEM —
Without protection, sensitive data leaks to AI chatbots.
Employees use AI tools in their daily work. Many organizations lack visibility into which tools are being used, what data is being shared, and where that data ends up.

PSEUDONYMIZATION
Replace real data with usable pseudonyms
Redactprompt replaces names, numbers, and other sensitive information with fictional variants that AI chatbots can still understand. This gives you useful answers, without sending real data.
- Consistent within each conversation: the same input always gets the same pseudonym
- Fictional data cannot be traced back to real people
- Works on names, IBAN, email addresses, phone numbers, dates of birth, and your own number ranges

Frequently asked questions.
Don't see your question here? Send us a message. We usually reply within one business day.
What exactly does Redactprompt detect?
IBAN with checksum validation, email addresses, phone numbers, dates of birth,
and credit card numbers. National identifiers for the Netherlands (BSN), the UK (NINO, NHS number)
and the US (SSN, ITIN). Plus API keys from more than 60 providers, including OpenAI, AWS, Stripe,
and GitHub. For anything with a format of your own, such as customer or invoice numbers, you add
your own rules. Name and address detection is currently trained on Dutch data.
Does my data go anywhere?
No. Everything is processed locally in your browser. With an organisation subscription,
the extension only sends metadata to the dashboard (type of detection, when, which chatbot).
Never the content of your prompt. The extension also works fully offline.
Does it work on Safari or Firefox?
Currently only Chrome and Chromium-based browsers (Edge, Brave, Arc). Firefox is
on the roadmap. Safari will follow depending on Apple's support for browser extensions.
Can my employer see what I type?
No. With an organisation subscription, your employer only sees metadata about detections
(type, frequency), never the content of your prompts. All logging is anonymized.
How long does a rollout in an organisation take?
A typical rollout takes 1 to 3 days: setting up the sign-on integration,
configuring policies, and deploying the extension via Intune or Jamf. Dedicated support guides
the entire process.
Is Redactprompt open source?
The detection engine and pseudonymization rules are released as open source.
The dashboard and organisation features are closed source. This lets anyone independently verify
that no data is leaked.
Does it work on macOS and Windows?
Yes. The extension works on any Chromium browser, regardless of the underlying OS.
The dashboard works in any modern browser on macOS, Windows, and Linux.
