Unzip the download, then open Kelven (on Windows, open Kelven.exe inside the folder). Desktop editions need an internet connection for sign-in and cloud AI. When you choose on-device AI, processing runs on your computer. These first packages are not signed by Apple or Microsoft; installation may show a security warning. On Mac, you may need to choose Open from System Settings → Privacy & Security.

The desktop app protects what you type in Kelven. It cannot see messages typed directly into ChatGPT, Gemini, or Perplexity. Use the separate Browser Shield for those sites.
