About AgentCloak
AgentCloak Desktop is a free privacy tool from AgentCloak (by InCountry, a CB100 2026 top AI company backed by $50M in funding) that swaps sensitive personal data for realistic synthetic substitutes before a prompt reaches any AI chatbot, then restores the real values in the reply the user sees. It detects first and last names, email addresses, phone numbers, URLs, social security and tax ID numbers, bank routing and account numbers, and physical addresses, running entirely on-device via a compact model — no data is sent to AgentCloak's own servers to use the free product. It installs as a browser extension for Chrome, Safari, or Edge, or as a native desktop app for Mac and Windows, and works with ChatGPT, Claude, Gemini, Grok, Copilot, and DeepSeek. The free Desktop product supports English, Spanish, French, German, Italian, Portuguese, and Dutch. Organizations needing company-wide deployment, audit logs, and enterprise identity login can upgrade to AgentCloak Server, sold separately on a custom quote. InCountry has raised $50M in total disclosed funding as of its September 2025 Series B round, from investors including Felicis Ventures, CRV, Bloomberg Beta, Caffeinated Capital, Mubadala, and Accenture (Tracxn, verified 2026-09-30).
