Prompt Leak Guard helps you catch leaked API keys, tokens, webhooks, signed URLs, database credentials, private keys, and private-data patterns before they leave your prompt box.
v0.1.4 adds risk receipts: each scan tells you what matched, why it matters, what to do next, and what a safer prompt should look like. The popup scans while you type, copies sanitized output, and can copy a plain-text receipt for review notes.
Use the free local web scanner for a quick check, or install the browser utility from the Microsoft Edge Add-ons Store or Mozilla Add-ons. The landing page links to both stores and the $4.99 installable package.
Launch code LAUNCH20 gives 20% off the first 100 purchases.
It is built for the moment before you paste logs, configs, GitHub issue text, agent context, support notes, or client snippets into AI chats and coding agents.
Local-first heuristic checks only. No account is required for the free scanner, and the scanner runs in the browser. It is a warning layer, not a compliance product or a guarantee that text is safe to share.
Launch proof: published on Microsoft Edge Add-ons, live on Mozilla Add-ons, approved on JunkStartups, and awarded gold on Noonlaunch.
