— 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.

— HOW IT WORKS —
Three steps. For users and organizations.
Install individually or roll out centrally. No complex setup. Works right away on ChatGPT, Copilot, and Gemini.
Install Redactprompt
Use Redactprompt directly in Chrome or Edge, or roll out the extension across your organization with centralized policies.
Use AI chatbots as usual
Redactprompt detects sensitive data locally before it is sent to AI chatbots.
Protect sensitive information
Sensitive information can be redacted or pseudonymized before it is sent.
REAL-TIME DETECTION
Protects sensitive data while you type.
Redactprompt detects personal data, customer data, and API keys before they are sent to AI chatbots. Everything happens locally in your browser.
- BSN, IBAN, email, phone numbers, and other sensitive data
- API keys from OpenAI, AWS, GitHub, Stripe, and 60+ others
- Fully local in your browser, with no telemetry or server calls

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, BSN, IBAN, email, phone numbers, postal codes, and more

— FAQ —
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?
Personal data such as BSN, IBAN, Chamber of Commerce numbers, credit card numbers,
email addresses, phone numbers, addresses, and postal codes. Plus API keys from more than 60
providers, including OpenAI, AWS, Stripe, and GitHub. All patterns work in both Dutch and English.
Does my data go anywhere?
No. Everything is processed locally in your browser. For premium and enterprise,
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 enterprise, your employer only sees metadata about detections
(type, frequency), never the content of your prompts. All logging is anonymized.
How long does an enterprise setup 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 enterprise 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.
