Nexu

nexu is an open source desktop app that runs an OpenClaw based AI agent and connects it to the messaging tools a person already uses. It is built with a particular focus on Feishu, and also supports WeChat, Slack and Discord. The goal is to let users talk to an agent inside their chat app and have it handle tasks, without working in a terminal or editing config files. Installation is a download and double click on a Mac, and the vendor says the first agent is ready within a minute. Users can switch between Claude, GPT, Gemini and other models through a graphical interface and bring their own API key, with no login required. The vendor states that configuration and state stay on the user's device, that no business data is hosted by nexu, and that the code is MIT licensed and open to audit and forking. Built in skills cover OpenClaw and Feishu functions such as search, tasks, calendar events, documents, sheets and meetings. The site gives examples such as a developer dropping an error screenshot into Feishu and the agent locating the bug and drafting a fix. It is aimed at individuals and small teams who want an agent in their chat app with control over their data and their model choice. The app is free. The user pays only for whichever model provider key they supply, and the vendor lists no subscriptions or per seat fees.
