PromptSafe - PII Protection for AI

Use ChatGPT and Claude on real work documents. Extract, detect sensitive data, and anonymize — all locally in your browser.

Now you can actually use AI at work. PromptSafe lets you safely use ChatGPT and Claude with real documents — client contracts, HR files, legal briefs, financial records — without exposing anyone's personal information. Instead of uploading sensitive files directly to AI tools (where they're stored on external servers), PromptSafe extracts the content locally, detects sensitive data, and replaces it with readable placeholders like [PERSON_1] or [COMPANY_2]. The AI gets the context it needs. The real data never leaves your device. HOW IT WORKS Click the PromptSafe icon while on ChatGPT or Claude Drop a document (PDF or DOCX), paste text, or type directly in the side panel Click "Scan for Sensitive Data" — names, emails, phone numbers, addresses, IDs, and more are automatically detected Review the highlighted items — add anything missed, remove false positives, or change categories Click "Anonymise & Inject" — the safe text is pushed directly into the AI chat, ready to send When the AI responds, use "Revert to Original" to restore the real names in the output WHY PROMPTSAFE? ✓ 100% local processing — your documents never leave your browser. Verify it yourself in DevTools. ✓ Readable placeholders, not black boxes — [PERSON_1] keeps the document understandable for AI and humans. ✓ Reversible — get your AI response, then restore the original data using the Restoration Key. ✓ Automatic detection — no need to manually find every name and email across a long document. ✓ Manual review tools — highlight anything the scanner missed, or use Search to find every occurrence of a name across the entire document. Catch one, catch them all. ✓ Works on ChatGPT and Claude — sits right in the interface, no tab-switching.
