What Is MaskMyPrompt?

Claim this Tool

MaskMyPrompt is a lightweight, browser-based tool that anonymizes your prompts before you share them with ChatGPT or other AI assistants. You enter your original text, including real names, companies, or locations, and the tool generates an anonymized version that preserves context while replacing sensitive details with made-up ones.

All processing happens locally in your browser, and the site states that prompts are never stored or sent to a server, emphasizing privacy and control. This makes MaskMyPrompt especially useful for professionals who need to discuss confidential projects, clients, or internal data with AI while remaining compliant and discreet. It helps developers, product teams, legal professionals, consultants, researchers, and privacy officers safely leverage AI on real-world information.
