Use AI on real work — reveal nothing you’re not allowed to.
Strippr redacts every piece of personally identifiable and confidential data from your text before it reaches ChatGPT, Claude or Gemini — so you get the answer and stay compliant with GDPR and your duty of confidentiality. In your browser. No account. Nothing logged.
Free forever for individuals · Works on ChatGPT, Claude, Gemini, Outlook — anywhere you can paste text.
“Draft a reply to Jane Andersen, CPR 250490-1234, regarding her case at Nørregade 12. She can be reached on +45 40 12 34 56.”
Hover a bar to see the data that never leaves your browser.
The prompt is the leak.
Every time a case detail, a patient name or a CPR number goes into a chatbot, personally identifiable data lands on someone else’s server — and, for a regulated professional, that can be a breach of confidentiality and of GDPR before you’ve even read the answer.
Banning AI isn’t realistic; your team already uses it. The fix isn’t policy — it’s removing the identifiable data from the text the moment before it’s shared. The AI still sees the problem; it just never sees who it belongs to. That’s the one job Strippr does, and it does it without ever seeing your words.
Redact it, ask the AI, get the real answer back.
Each identifier becomes a label like [NAME_1] — so the AI’s reply can be restored below.
Safe-to-paste text appears here.
This demo runs the extension’s own checksum-validated engine — CPR, IBAN and card numbers are verified, not just pattern-matched — entirely in your browser. Your text is never sent anywhere.
If confidentiality is your job, this is your keystroke.
Law firms
Client confidentiality is a professional duty, not a checkbox. Strip names, CPR and case numbers before you draft, summarise or translate with AI.
Clinicians & clinics
Patient data falls under health-record law. Redact CPR, diagnoses and next-of-kin in one keystroke before a chatbot ever sees the note.
Social workers
Case files hold the most sensitive data there is. Anonymise a report before you ask AI to tidy the language or draft a plan.
Accountants & advisors
Personal financials, CVR and IBAN cleared before they reach a model — so you get the speed of AI without the exposure.
HR & people teams
Employee data stays employee data. Redact before you rewrite a review, a warning or a reference letter.

We can’t leak what we never receive.
Most “privacy” tools ask you to trust their servers. Strippr removes the server from the equation entirely. The redaction engine is a set of pure functions that run in your browser tab.
Zero network calls
The extension makes no requests. Your text is processed and stays on your device.
No account, no login
The core tool is fully usable with no sign-up. There is no user record to breach.
No content telemetry
We never transmit your words. Only anonymous aggregate counters, and only with opt-in.
Checksum-validated
CPR mod-11, IBAN mod-97, Luhn on cards — real IDs caught, look-alikes left alone.
GDPR by architecture
Because processing is local, there is no transfer, no controller relationship over your text.
Open to audit
The pattern set is a security-adjacent artefact and is built to be reviewed independently.
Don’t paste data you’re not allowed to share.
Install it in a minute, or bring it to your whole team. Either way, nobody leaves this page without a way to use AI safely.
