# PromptHush

> PromptHush is a Chrome extension and web service that acts as a privacy firewall for AI prompts. It scans text before submission to ChatGPT, Claude, Gemini, Perplexity, Copilot, and other AI tools, detecting sensitive data (API keys, emails, phone numbers, tax IDs, medical info, legal details, client names, financial figures) and replacing them with safe placeholders — all locally in the browser.

Key facts:

- All detection and redaction happens locally in the user's browser — no prompt data is sent to PromptHush servers
- Works as a Chrome extension that activates on supported AI chat interfaces
- Free tier: 30 scans/month; Personal: $19/mo for 2,000 scans; Professional: $30/mo for 10,000 scans
- Users can add custom private terms for clients, projects, and companies
- Supports custom detection categories: API keys, passwords, tax IDs, medical info, legal details, emails, phone numbers, client names, financial figures
