Local-only browser extension

Catch secrets before they leave the prompt box.

Prompt Leak Guard scans AI prompts, debug logs, and config snippets for common API keys, cloud/service tokens, webhooks, private keys, signed URLs, credential-bearing database URLs, payment cards, email, phone, and dashed US SSN patterns before you paste them into AI tools.

A narrow tool for a very expensive mistake.

Designed for developers, operators, analysts, and AI power users who paste real work into AI tools and need a fast local safety check first.

Secret detection

Flags common AI provider keys, AWS/Azure/GCP credentials, GitHub/GitLab/npm/PyPI tokens, chat/webhook URLs, payment/email/ops platform keys, bearer tokens, validated JWTs, private keys, and credential-bearing database URLs.

Prompt sanitizer

Replaces sensitive values with readable placeholders so the prompt keeps its shape without leaking the real value.

Live page warning

On supported AI chat pages, the extension warns when high-risk content appears in the active prompt field.

Built to stay boring.

No account, no cloud scanner, no analytics SDK, and no remote model call. The detection engine runs in the browser and outputs sanitized text locally.

No server dependency

The extension is static JavaScript. There is no backend to maintain and no API bill to cover.

Auditable package

The launch ZIP includes the detector code, popup, options page, and manifest so buyers can inspect what is installed.

Simple license shape

Paid access uses an offline license code. Activation is local, with no account system or server check.

Clear limits, clean handoff.

The launch build is intentionally small: one local utility, one job, no account system, no background service.

Does it catch every secret?

No. It catches common high-risk patterns and helps prevent obvious accidental leaks. It is a safety check, not a guarantee or a replacement for secret rotation.

What do buyers receive?

A packaged browser extension ZIP, license code, install notes, privacy/support docs, and the auditable detector code included in the extension package.

Where does it run?

In Chromium-style browsers through Manifest V3. The content warning is scoped to supported AI chat pages listed in the privacy policy.
