About OpenClaw

About AionUi
AionUi is an open source, cross platform Cowork application that puts AI agents to work alongside the user on their own computer. It is written in TypeScript and released under the Apache 2.0 license, and it lives in the AI agent and chat tooling ecosystem alongside the command line agents it is built to host. Rather than acting as a plain chat client, it runs a built in agent engine that can read and write files, search the web, generate images, and call Model Context Protocol tools, while showing the user every action the agent takes and keeping approval in the user's hands.
