# 免费联网模式

想不花钱就让 AI 联网？Cherry Studio 有两种 **免费** 方案，都不需要付费 API：

## 方案一：默认的 Exa MCP（开箱即用、免密钥）

Cherry Studio **默认** 就把搜索服务商设成 **Exa MCP**——走公开端点、**无需任何 API 密钥**。装好后，在对话输入框点 🌐 **小地球** 图标对当前对话开启联网即可，无需额外配置。

详见 [联网模式](/pre-basic/settings/websearch.md)。

## 方案二：SearXNG（自托管、完全免费）

如果你愿意自己部署，**SearXNG** 是开源的元搜索引擎，可完全本地 / 自建服务器运行、不限调用次数，隐私也更可控。

部署与接入步骤见 [SearXNG 本地部署与配置](/pre-basic/settings/websearch/searxng.md)。

{% hint style="info" %}
想要更强的检索效果、或用 Tavily 这类 **需要密钥** 的服务？那属于在 [联网模式](/pre-basic/settings/websearch.md) 里另配搜索服务商，不在"免费"范围内。
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cherryai.com.cn/pre-basic/settings/websearch/free-search.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
