CowAgent

CowAgent is an open source personal AI assistant and agent harness that plans multistep tasks, calls tools and skills, and keeps long term memory so it improves over time. It runs continuously on a laptop or server, installs with a single command on Linux, macOS, Windows or Docker, and also ships as a desktop app. It suits developers and power users who want an always on assistant reachable from the chat apps they already use. One agent can connect to Telegram, Slack, Discord, WeChat, Feishu, DingTalk, WeCom, QQ, official accounts, the web and the terminal. Models are pluggable across OpenAI, Claude, Gemini, DeepSeek, Qwen, GLM, Kimi, MiniMax, Doubao and LinkAI. Memory uses a three tier design with hybrid keyword and vector retrieval, a knowledge base curates notes into a linked Markdown wiki, and built in tools cover files, terminal, browser, scheduler and web search with native MCP support. Skills install from Skill Hub, GitHub or ClawHub or can be written in conversation, and several agents with distinct roles can collaborate as a team with delegation and sub agents. The software is free under the MIT license. A hosted option, which runs the assistant in its own cloud computer, is offered through the LinkAI platform, but no prices are published on the CowAgent site. The project was previously published under a different name and has been officially renamed CowAgent; the old GitHub repository address now redirects to the new one.
