As answered by people managing Modular JavaScript and SafePrivacyMask.dev.
SafePrivacyMask.dev's answer:
Choose Safe Privacy Mask if you want lightweight, free protection against accidentally sharing sensitive text with AI tools, without setting up a cloud service or an enterprise security platform. Masking runs locally in your browser, and custom rules let you cover terms specific to your work.
It is an aid for individual browser workflows, not a replacement for organization-wide DLP, access controls, or approval processes.
SafePrivacyMask.dev's answer:
Safe Privacy Mask combines local browser-based masking with preset detection and custom replacement rules. It replaces sensitive text in input fields before it is sent to AI tools, without uploading the original text to an external masking service. Users can add customer names, project names, custom words, or regular-expression rules. The extension is free and requires no account or subscription.
SafePrivacyMask.dev's answer:
People who use ChatGPT, Claude, Gemini, and other web-based AI tools with work material such as emails, support messages, logs, code, and customer or project information. It is especially useful for individuals and small teams who want to reduce accidental disclosure while keeping masking local to their browser.
