Sigma Vision

Sigma Vision blocks adult content on Windows and Mac using on-device AI. It monitors the screen in real time, warns on detected explicit content, and enforces a full device lock if limits are exceeded. A blocklist stops known sites before they load, while screen-level analysis catches content beyond URLs. Family plans include dashboards and email alerts, and all detection stays on your machine to protect privacy. Use it to support healthier habits and safer shared devices. View startup
