PasteCloak is a desktop app for macOS and Windows that detects and masks secrets (API keys, tokens, passwords, private keys) in your clipboard before you paste them into ChatGPT, Claude, Slack or a support tool. Everything runs locally on your computer.
The beta is open to developers, IT admins and professionals who handle sensitive data. Testers get early access to the beta build, install instructions, and a direct line to send us feedback. The beta runs on macOS; the Windows version will be available at launch. Free during the beta.
