Brave Search 是由 Brave Software 开发的搜索引擎。
  • Brave Search 使用自己的网络索引。截至 2022 年 5 月，其索引已覆盖超过 100 亿个页面，92% 的搜索结果无需依赖任何第三方即可提供，其余结果通过服务端从 Bing API 获取，或（在用户选择启用的情况下）在客户端从 Google 获取。据 Brave 表示，该索引被”有意保持得比 Google 或 Bing 更小”，以帮助避免垃圾内容和其他低质量内容，但代价是”Brave Search 在处理长尾查询方面尚不如 Google 出色”。
  • Brave Search Premium：自 2023 年 4 月起，Brave Search 是一个无广告的网站，但最终将切换到包含广告的新模式，高级用户可获得无广告体验。默认情况下，不会向用户收集 IP 地址等数据。选择加入数据收集需要高级账户。
