Install it once. Every AI tool on your computer is protected automatically.

Install

Download the macOS app. It automatically finds every AI tool on your computer — ChatGPT, Claude, Copilot, everything.

Activate

Every prompt to any AI provider goes through Shield first. Names, addresses, passwords — all redacted locally before anything hits the internet.

Relax

You use AI normally. Shield works silently in the background. Weekly digest: "This week Shield blocked 47 passwords, 3 credit cards, and 12 addresses."
