PromptVerify – Verify Sensitive Data Before You Send

Automatically verify prompts and files for API keys, passwords, tokens, and other sensitive data before they reach AI. 100% local.

PromptVerify scans what you type or upload to AI chat assistants and verifies prompts and files for API keys, passwords, access tokens, secrets, session credentials, and personal information such as emails, phone numbers, and ID numbers before they leave your browser. WHY IT MATTERS It's easy to paste a configuration file, stack trace, source code, or support ticket into an AI chat without realizing it contains sensitive information. PromptVerify helps you catch it before it's sent—not after. HOW IT WORKS • Pattern matching detects common secret formats, including cloud provider keys, hosting tokens, payment service keys, messaging API keys, and more. • Entropy analysis identifies high-randomness strings that may contain secrets, even if they don't match known patterns. • File scanning verifies uploaded text-based files, including source code, configuration files, JSON, YAML, Markdown, SQL, and more. • A verification report shows detected sensitive information so you can review the results, redact it if needed, or continue with confidence. WORKS WITH AI CHAT TOOLS PromptVerify helps verify prompts and uploaded files before they are submitted through supported AI chat interfaces. PRIVACY BY DESIGN • Local verification is performed on your device. • No cloud uploads. • No analytics, tracking, or telemetry. • Local verification history so you can review previous detections. • Custom detection rules and a trusted-site whitelist keep you in control. Turn verification on or off anytime from the toolbar icon, and customize detection rules from the settings page.
