Stop hand-cleaning prompts before using AI. Pasting client emails, contracts, and proposals into ChatGPT or Claude risks breaching NDAs. MaskMyPrompt solves this 100% inside your browser: • Zero Cloud Storage: 0 network requests. • Auto-Tokenization: Replaces emails, phone numbers, deal figures, and company names with temporary tokens. • Custom Keywords: Easily register project codenames and client names. • 1-Click Restoration: Restore real data instantly after AI replies.


Hey Product Hunt! 👋
I built MaskMyPrompt because of a constant fear I had while freelancing:
"What if I accidentally leak my client's confidential data or violate an NDA by pasting raw text into ChatGPT or Claude?"
Most sanitization tools send your data to another server.
Here is what MaskMyPrompt solves right inside your browser:
🔒 100% In-Browser Isolation: Zero network calls. Open Chrome DevTools (Network tab) and verify zero requests yourself.
⚡ Two-Way Tokenization: Automatically masks emails, phones, amounts, and custom secret words into tokens like {{SECRET_1}}. Paste the AI's reply back, and it restores the original text in 1 click.
💼 Built for client workers & consultants handling sensitive work daily.
