SecretShields masks sensitive data by default. When you intentionally paste a secret, we track the exposure and remind you to rotate it later.
Free forever. Zero telemetry. No network calls.
When you move fast with AI coding assistants, you inevitably paste `.env` files, stack traces, and configurations. By operating at the OS clipboard layer, SecretShields catches secrets before they ever touch a chat input, terminal, or browser.
Protects Cursor chat, VS Code Copilot, web-based ChatGPT, terminal CLIs like Claude Code, and even Slack. If you can paste it, we protect it.
Zero network calls. No telemetry. Your secrets never leave your machine. SecretShields runs 100% locally with high-performance regex and entropy checks.
Need the real key? Click "Restore for 60s". We put the raw key back in your clipboard for a short window, then automatically trigger a rotation reminder.
Every detector can be individually toggled via settings. Built-in allowlists, entropy checks, and structural validation keep false positives near zero.
SecretShields operates on the system clipboard. Once masked text is written, it becomes the clipboard's actual content at the OS level. Uninstalling the extension does not (and should not) restore raw secrets — that would be a security regression. Simply copy any other text to overwrite the clipboard.
VS Code extensions run in a sandboxed Node.js process with no DOM access. SecretShields cannot intercept paste events inside chat panels (Cursor, Copilot, Cline). Instead, it masks the clipboard before you paste — so any paste target receives the masked version automatically.
No. Detection, masking, and alerts are entirely local. No telemetry, no data leaves your machine, and no raw secrets are ever written to disk.
Install SecretShields for free and never worry about accidentally pasting production credentials into an AI chat again.
