How Prompt Cleaner works
Three steps to protect your private data from AI training and logging.
1. Paste your text
Copy any prompt, email, document or conversation that contains sensitive data and paste it into the input box.
2. We scan & redact
Our server-side regex engine detects emails, credit cards and IP addresses and replaces them with safe placeholder tokens instantly.
3. Copy & send safely
Get your clean, AI-optimized prompt wrapped in a professional instruction frame. Paste it into any AI tool with zero risk.

Frequently asked questions
Everything you need to know about AI prompt privacy.
How do I remove PII from a ChatGPT prompt?
Paste your text into Prompt Cleaner and click "Clean Prompt". The tool automatically detects and removes emails, credit card numbers, and IP addresses using server-side regex processing in under 100ms. The cleaned, anonymized text is ready to paste into ChatGPT, Claude, or any other AI model without exposing private data.
Is Prompt Cleaner GDPR and CCPA compliant?
Yes. Prompt Cleaner processes text server-side and immediately discards it — we never store, log, or analyze your prompts. This makes it suitable for GDPR compliance in Europe and CCPA compliance in California. We only store anonymous IP usage counts to enforce the free tier limit. No personal data is retained after processing.
Why should I clean prompts before using AI tools?
AI models like ChatGPT and Claude may use your inputs for training or log them for safety reviews. If your prompt contains real email addresses, credit card numbers, or IP addresses, that sensitive data could be exposed or retained by the AI provider. Prompt Cleaner removes all PII before your text reaches any AI service, protecting both you and your clients from data leaks.
Does Prompt Cleaner work with Claude, Gemini and Copilot?
Yes. Prompt Cleaner is completely AI-agnostic. The cleaned output works with any text-based AI model: ChatGPT (GPT-4o, GPT-4), Anthropic Claude, Google Gemini, Microsoft Copilot, Mistral, LLaMA, and any other LLM or chat interface. Simply copy the anonymized output and paste it anywhere.
What is the AI prompt injection frame?
After removing sensitive data, Prompt Cleaner wraps your text in a professional instruction frame that tells the AI model to act as an expert analyst. This significantly improves the quality and structure of AI responses compared to sending raw text. The frame includes clear delimiters so the AI understands where your content starts and ends.
How many free requests do I get per day?
You get 3 free prompt cleanings per day, tracked by IP address with no account required. For unlimited access, upgrade to the Pro plan for $2.99/month or get a 24-hour pass for $1.49 — ideal when you need to clean a large batch of prompts right now. Pro access works across all your devices with a single login.
Is there a limit on text length?
Free users can clean prompts up to 50,000 characters per request — enough for any typical AI prompt or document. Pro users have no length restrictions. The processing is handled entirely on our server using native Python regex, so performance stays under 100ms regardless of text length.
