A client-side structural defense against code and secret leakage
Intercept sensitive paste and typed content before it reaches external cloud tools - without sending your payloads to us.
SourceCloak is a client-side Chrome extension designed to prevent proprietary code and secrets leaks. It runs 100% local AI and regex engines, intercepting copy/paste actions on monitored AI surfaces before they reach the web.
A 4-tier defense pipeline (regex, token scoring, ONNX WASM, optional Gemini Nano) blocks sensitive pastes locally. 100% free and open-source under the MIT license.
