CleanMyPrompt
Private Prompt Security · Global Compliance Ready · Zero Server Processing

The Definitive Shadow AI Firewall.

Intercepts PII, API keys, and secrets before they reach ChatGPT, Claude, or Gemini. Every regex runs in a Web Worker inside your browser — zero bytes sent to any server.

Compliance heads-up: GDPR data minimisation, CCPA, HIPAA, and the EU AI Act all restrict sending personal data to third-party AI platforms. Redact before you prompt.

How we prove it runs offline

340ms

Latency

No round-trip to a server. Every clean runs locally in your browser the moment you click.

vs. ~340 ms avg for cloud-based PII tools

In-Browser

Engine

PII detection, PDF extraction and OCR all run inside your browser tab. Nothing is sent to a server — scanned-page OCR even uses WebAssembly (Tesseract.js) entirely offline.

No runtime network dependencies

128

Server Requests

Zero bytes of your prompt ever leave this tab. Open DevTools → Network and verify it yourself.

Network tab → XHR filter → empty

Under the hood

Clean in three steps

Paste Your Prompt

Drop any text — code snippets, emails, support tickets, SQL queries — into the editor. Works with anything you'd normally send to an AI.

Scan & Detect

A local regex + NLP engine identifies emails, phones, AWS keys, API secrets, SSNs, EU VAT IDs, German addresses, and 30+ other PII types across English, German, French, and Spanish — entirely inside your browser.

Copy Clean Prompt

Every sensitive token is replaced with a labelled placeholder like [EMAIL] or [AWS_KEY]. Zero bytes leave your device. One click to copy.
