AgentCloak, a CB100 2026 top AI company, today announced AgentCloak Desktop, a free Sovereign AI product that turns the chatbots people already use into privacy-preserving AI. AgentCloak Desktop replaces private data with synthetic substitutes on the user’s device before anything goes to a frontier AI, and then restores the original values in the model’s reply.

AgentCloak Desktop detects sensitive fields locally and swaps them with consistent digital twins.

AgentCloak Desktop detects sensitive fields locally and swaps them with consistent digital twins.

As employees and individuals paste emails, contracts, customer records, and personal details into ChatGPT, Claude, Gemini, Grok, Copilot, DeepSeek, and other AI Chatbots, those prompts routinely expose names, addresses, account numbers, and identifiers to the models. Even retention promises and enterprise agreements expose sensitive data. AgentCloak Desktop addresses the problem at the source: Zero Data Sending. The model never gets the real values.

AgentCloak Desktop provides the privacy benefits of Sovereign AI while still using frontier models, without the expense and hassle of the expensive hardware, staff, and security required to maintain Sovereign AI infrastructure.

“People should not have to choose between useful AI and keeping their private data private,” said Peter Yared, Founder & CEO of AgentCloak. “AgentCloak Desktop puts Sovereign AI on the device you already have. ChatGPT, Claude, Gemini, Grok, Copilot, and Deepseek still do the heavy lifting. They just never see private data like names, addresses, or account numbers. That is Zero Data Sending, not an ambiguous policy footnote.”

Cloaked on the way out, restored on the way in

AgentCloak Desktop detects sensitive fields locally and swaps them with consistent digital twins. “Peter Parker” becomes “Julio Schmidt.” “364 23rd St” becomes “401 Vanessa Curve.” The AI still has the context it needs to answer. When the reply comes back, AgentCloak uses the same personal digital twin to put the real values back in front of the user. The original never left the device.

The product pairs deterministic rules with a compact neural model that runs entirely on the user’s computer or inside the browser. Users keep their existing AI workflows. No new chatbot. No data uploaded to AgentCloak to use the free Desktop product.

Where it runs

AgentCloak Desktop installs as a browser extension for Chrome, Safari, and Edge, or as a native app for Mac and Windows for users who use desktop AI Chatbot clients. AgentCloak Desktop adds data protection to ChatGPT, Claude, Gemini, Grok, Copilot, and DeepSeek.

What the free product detects and cloaks

First and last names

Email addresses

Phone numbers

URLs

Social Security and tax ID numbers

Bank routing and account numbers

Physical addresses

Languages supported in the free Desktop release: English, Spanish, French, German, Italian, Portuguese, and Dutch.

Key capabilities

Zero Data Sending: private fields are replaced on-device before the prompt is submitted; this is not a retention or “we won’t train on your data” promise.

Digital twins: synthetic substitutes stay consistent so the model can reason about people, places, and accounts without seeing the originals.

Round-trip restoration: real values are swapped back into the answer so the user sees a usable reply.

Works with the AIs people already: installs as a browser extension or desktop app rather than forcing a new, closed assistant that is expensive to run, hard to upgrade, and doesn’t connect scalably to the web.

On-device Sovereign AI: Rampart, a compact model from the U.S. government that mixes deterministic detection and neural detection of sensitive data runs completely on-device and is combined with AgentCloak digital twin technology.

Free to install for individuals; AgentCloak Server extends the same approach to teams and regulated enterprises.

AgentCloak Server adds even more power for organizations

Organizations that need company-wide protection can upgrade to connect AgentCloak Desktop with AgentCloak Server, an AI-native Rust container that deploys in any cloud, on-premises, or air-gapped environment. AgentCloak Server adds cloaking of uploaded files, richer digital twins that keep related values grouped across prompts, generalization of terms and numeric ranges, vertical data-protection packs for financial services, contracts, healthcare, and legal, and MCP data protection for Salesforce, HubSpot, and other apps.

With AgentCloak Server, IT departments can push a preconfigured AgentCloak Desktop with Intune and similar tools, collect audit logs, and use Microsoft Entra, Google Workspace, or Okta login. Cross-border data protection is also available with worldwide InCountry Sovereign Data proxies.

AgentCloak Desktop is available now at no charge. Install the browser extension or desktop app at agentcloak.ai/desktop.
