Clean Prompts. Zero Data Leaks.
CleanMyPrompt is a free, open-source toolkit that helps developers, enterprises, and privacy-conscious users clean, redact, and compress text before sending it to AI models — without their data ever leaving the browser.
Our Mission
Every day, millions of people paste sensitive information into AI chatbots — email addresses, API keys, internal code, medical records, legal contracts. Most don't realize that data may be logged, used for training, or exposed in a breach.
CleanMyPrompt exists to close that gap. We provide a fast, private preprocessing layer that strips personally identifiable information, compresses tokens to reduce costs, and formats messy text for optimal AI comprehension — all without a single byte leaving your device.
What Makes Us Different
Privacy by Default
All text processing happens in your browser. No data is transmitted, logged, or stored on any server.
Deterministic Engine
We use regex patterns and NLP rules — not AI models — to detect and redact sensitive information. Predictable, auditable, fast.
Full Transparency
The detection rules are open source. You can inspect every pattern we match, audit the logic, or self-host the application.
Zero Friction
No sign-up, no API key, no paywall. Paste text, clean it, copy the result. Works offline after the first load.
Built for Compliance
Designed with GDPR, EU AI Act, and HIPAA considerations in mind. Export audit logs for enterprise compliance documentation.
Security First
Detects API keys, credit cards, SSNs, emails, phone numbers, IP addresses, and more. Runs entirely client-side so secrets never touch a network.
How It Works
Paste or upload. Drop in text from a PDF, email thread, code snippet, log file, or image (OCR).
Choose a mode. Clean (fix formatting), Squeeze (compress tokens), or Format (structure as JSON). Toggle PII redaction on or off.
Copy the result. Your cleaned text is ready for ChatGPT, Claude, Gemini, Llama, or any LLM. Nothing was sent to any server.
Technology
- Detection: Deterministic regex + Compromise.js NLP. No machine learning models.
- Runtime: Client-side JavaScript via Web Workers. Falls back to main thread when unavailable.
- OCR: Tesseract.js (WebAssembly) for in-browser image-to-text extraction.
- Framework: Next.js with static pre-rendering for fast load times and SEO.
- Storage: localStorage only. No cookies for content. No IndexedDB. No server persistence.
