Frequently asked questions
Why should I clean my prompts before using AI?
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. Prompt Cleaner removes all PII before your text reaches any AI service.
Does Prompt Cleaner store my text?
No. Your text is processed server-side using regex patterns and immediately discarded. We only store anonymous usage counts per IP address to enforce the free tier limit. We never read, log, or analyze the content of your prompts.
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 improves the quality and structure of AI responses significantly compared to sending raw text.
Which AI tools is this compatible with?
Prompt Cleaner is AI-agnostic. The cleaned output works with any text-based AI: ChatGPT, Claude, Gemini, Microsoft Copilot, Mistral, LLaMA, and any other LLM or chat interface. Just copy the anonymized output and paste it anywhere.
