How it works
Pattern-match against known secret formats
The scan runs real regex checks for AWS keys, GitHub and Slack tokens, Stripe/OpenAI-style keys, private key blocks, database connection strings, and generic credential assignments.
Review flagged matches and fix before shipping
Each match is grouped by severity with a redacted sample, so you can locate and remove real secrets before they reach a repository or a teammate.

Frequently asked questions
How is this different from the Prompt Privacy Scanner?
The Prompt Privacy Scanner checks a prompt before you submit it to an AI tool. This tool scans code or AI-generated output after the fact, for the same kind of secrets and unsafe config — a different artifact and a different point in the workflow.
What kinds of secrets does it detect?
Pattern matches include AWS access keys, GitHub/Slack/Stripe/OpenAI-style tokens, PEM private key blocks, JWTs, database connection strings with embedded credentials, basic-auth URLs, and generic api_key/secret/password assignments.
Will it catch every possible secret?
No. This is pattern-based detection, not a guarantee. Custom secret formats, obfuscated values, or secrets split across multiple lines can be missed — treat this as one layer, not a replacement for a dedicated scanner.
Does the code I paste get uploaded or stored?
No. The scan runs entirely in your browser using JavaScript regular expressions. Nothing is sent to a server, and pasted text is only kept in session storage to survive a refresh.
What should I do if it finds a real secret?
Remove it from the code, rotate the credential immediately, and move it into an environment variable or secrets manager. If it was ever committed to git history, rotation is required — deleting the line alone does not remove it from history.
Why does the score change based on destination?
The same exposed secret is a bigger risk if it is about to be committed to a public repository than if you are only reviewing AI output privately, so the score weights findings slightly by where the code is headed next.
How We Compare
