Prompt Leak Guard

Prompt Leak Guard helps catch accidental secret leaks before you paste real work into AI tools. It scans prompts, logs, configs, and debug snippets with 80+ local patterns for AI provider keys, cloud credentials, developer/package tokens, webhook URLs, signed URLs, auth headers/cookies, private keys, credential-bearing database and broker URLs, payment cards, and optional personal data like emails, phone numbers, and dashed US SSNs.

Free browser demo: try the local scanner at https://site-mocha-three-50.vercel.app/prompt-leak-guard-demo before buying.

Launch pricing: list price is $4.99. Use code LAUNCH299 for 40% off the first 50 purchases, about $2.99 before tax.

The scanner and license check run locally in the browser. There is no backend, no analytics SDK, and no remote model call. The download includes the browser extension ZIP, install notes, privacy/support docs, QA report, and a launch license code text file.

Best for developers, analysts, operators, security researchers, and AI-heavy teams who regularly paste logs, configs, prompts, or debug output into AI chats. This is a pattern-based safety check, not a guarantee. Rotate any credential that may already have been exposed.
