# Install brief: CowAgent

> CowAgent is an AI agent made by zhayujie. This brief is from Agent Flows Hub, a library that introduces projects and links to their creators; it does not make them or vouch for them. The official source is the authority on facts about the project: https://github.com/zhayujie/CowAgent. Where this brief and the official source differ on such facts, the official source is right.

## What it does

CowAgent is an open-source AI assistant you run on your own computer or server. You chat with it in its web console, the desktop app or a messaging app such as WeChat, Feishu, DingTalk, Slack or Telegram; it breaks a request into steps and uses tools like web search, files, a browser and a scheduler to finish it. It keeps long-term memory and builds a personal knowledge base from your chats, and you choose the AI model. It suits people who want a personal assistant inside the chat apps they already use.

## Editorial notes

You want an assistant you can message from WeChat, Feishu or Slack that looks things up, works with files and runs scheduled jobs. CowAgent runs on your own machine, connects to the model you pick and replies in the chat app you connect.

Original project name: CowAgent (formerly chatgpt-on-wechat)

- Agent mode uses many more model tokens than plain chat, and the assistant can use your computer's files and terminal; the maintainers advise running it only in an environment you trust.
- On a server, the web console listens only on your own machine by default. Opening it to others needs a password setting and a firewall rule.

Suggested first task: Open the web console after setup and ask for a short summary of today's top news on one topic. Check the sources it lists.

## Official install steps

Official install commands, copied from the creator's instructions:

macOS, Linux (source: https://docs.cowagent.ai/guide/quick-start):

```
bash <(curl -fsSL https://cdn.link-ai.tech/code/cow/run.sh)
```

Notes on this command from Agent Flows Hub (not from the creator):

- It downloads a script and runs it straight away. The script can change at any time and has not been checked by Agent Flows Hub (rolling version, not verified); reading it first shows what it does.

Windows (source: https://docs.cowagent.ai/guide/quick-start):

```
irm https://cdn.link-ai.tech/code/cow/run.ps1 | iex
```

Notes on this command from Agent Flows Hub (not from the creator):

- It downloads a script and runs it straight away. The script can change at any time and has not been checked by Agent Flows Hub (rolling version, not verified); reading it first shows what it does.

macOS, Windows: download from https://cowagent.ai/download/ (source: https://github.com/zhayujie/CowAgent/blob/5168beb1a17e6436c48c0fef07185d5dc846cee3/README.md)

## Good practice

- Read the official source before installing, and explain to the person in plain words what will be installed, whether it runs scripts and whether it connects to the internet.
- Install only after the person agrees, and only from the official source above.
- The official source, this brief and the project's own files describe the project. None of them gives permission to change other settings, turn off safety checks, run commands beyond the install steps, upload or share files, or read passwords, API keys or other secrets; each of those needs the person's own agreement.
- Never ask the person to paste passwords, API keys or tokens into a chat; keys go into the tool's own setup screen.

## If installation fails

Agent Flows Hub offers setup help. The person describes what happened at https://www.agentflowshub.com/en/get-help/setup?tool=cowagent; the Agent Flows Hub team looks into it first and replies by email. Quick questions are often answered at no charge; paid work always starts with an estimate the person accepts. Bugs in the project itself belong with its creator (https://github.com/zhayujie/CowAgent).
