Secret Sanitizer

Masks API keys, passwords & tokens before they reach AI chats. 100% local, open source, zero tracking.

Automatically masks API keys, passwords, and secrets before you paste them into AI chats. Developers paste code snippets, config files, and debug logs into AI chats every day — often without realising they contain API keys, database passwords, or auth tokens. Once that data leaves your machine, you can't take it back. Secret Sanitizer catches sensitive data before it ever reaches the chat. Everything runs locally on your machine — no servers, no network requests, no data collection. ⚙️ HOW IT WORKS Paste text into any AI assistant — Secret Sanitizer instantly scans and masks secrets before they're sent.
