Cloak your private data from AI Chatbots
Cloak your private data from AI Chatbots with the free AgentCloak browser extension
Don’t expose your data to AI.
Cloak it first.
AgentCloak Desktop turns the chatbots you already use into sovereign AI. It swaps private data with synthetic substitutes before anything leaves the page. With AgentCloak’s digital twins, “Peter Parker” becomes “Julio Schmidt.” “364 23rd St” becomes “401 Vanessa Curve.” That’s what the AI gets. Your original never does.
Cloaked on the way out.
Restored on the way in.
The AI gets the context it needs to reply. Then AgentCloak uses your personal digital twin to swap the real values into the answer. The AI never sees real names, addresses, or other private data!
Works with every popular AI
Keep using ChatGPT, Claude, Gemini, Copilot, Grok, and more. AgentCloak Desktop cloaks names, accounts, and other private details on your machine so the model never receives them. That’s Zero Data Sending, not a retention promise.
A compact Sovereign AI that runs entirely in your browser or on your desktop
Install AgentCloak Desktop as a browser extension in Chrome, Safari, or Edge. Using the desktop apps for your AIs? Install AgentCloak Desktop on Mac or Windows instead.
AgentCloak Desktop pairs digital twin cloaking with a small AI model that runs right on your computer. It mixes deterministic rules with neural AI so it’s a compact model that performs.

Frequently asked questions
AgentCloak Desktop cloaks data so AI never sees real names, addresses, or other private data. Private data is swapped before anything leaves the page, and restored only on your side when the answer comes back.
AgentCloak replaces private data with synthetic substitutes using digital twins. For example, “Peter Parker” becomes “Julio Schmidt,” and “364 23rd St” becomes “401 Vanessa Curve.” That is what the AI receives. Your original never does. The AI reply restores private day using your personal digital twin. The model still has the context it needs to answer, but it never sees the real names, addresses, or other private data.
A digital twin is AgentCloak’s mapping between real private values and the synthetic substitutes sent to the AI. The twin is used both to cloak outbound prompts and to restore original values in inbound answers.
Yes. The product page presents AgentCloak Desktop as free to install for individual use on a browser or desktop.
Go to Install AgentCloak Desktop, click the Install button, and pick your browser or desktop OS.
When the “Remember” feature is toggled on, AgentCloak Desktop will remember both your real values and the synthetic replacements. This way, you don’t have to approve the cloaking every time. The data is stored on your computer and is never sent to an AI.
