PromptSafe anonymises sensitive data in your text and documents before you paste them into ChatGPT, Claude, or any AI tool. Everything runs locally in your browser — no data is uploaded to any server. Drop in text or a PDF. PromptSafe automatically detects names, emails, phone numbers, addresses, financial data, ID numbers, and 15+ other entity types, then replaces them with reversible placeholders like [PERSON_1] and [EMAIL_1]. Paste the safe version into your AI tool. When you get the response back, restore the originals with one click. The Chrome extension works directly inside ChatGPT and Claude — anonymise before sending, restore after receiving, without leaving the AI interface. Built for professionals who use AI tools with confidential data: virtual assistants, freelancers, HR teams, and anyone handling sensitive client information. Key capabilities: Automatic detection of 18+ sensitive entity types Reversible placeholder vault — restore original data after AI processing Chrome extension for inline use inside ChatGPT and Claude PDF support with visual redaction Zero server contact — fully local browser processing Free tier available, no account required to start
