Agent.exe
Agent.exe is an open-source Electron desktop app created by Kyle Corbitt that leverages Anthropic’s Claude 3.5 Sonnet Computer Use API to let AI interact with desktop interfaces, click buttons, navigate browsers, and automate local computer tasks.
What is Agent.exe?
Agent.exe is an open-source Electron desktop application and developer proof of concept created by Kyle Corbitt. It enables Anthropic's Claude 3.5 Sonnet model to directly control a local computer using Anthropic's native Computer Use API. By processing screen captures and executing mouse and keyboard actions, Agent.exe allows Claude to perform tasks like navigating web browsers, filling forms, and managing files through simple text prompts.
Agent.exe is an open-source project hosted on GitHub with over 3,500 stars and hundreds of community forks. Written primarily in TypeScript (approx. 90%) and JavaScript within an Electron framework, the application was originally built as a rapid 6-hour proof-of-concept. It provides a lightweight local alternative to heavy container-based implementations, giving developers direct access to Claude 3.5 Sonnet's GUI control capabilities using their own Anthropic API credentials.
