为 AI 代理在你的 Postgres 上提供图、向量与文本检索
通过一个一致的接口同时查询图、向量、全文与混合检索，无需把多个系统拼在一起。
开源引擎 pgGraph 可跨记录沿关系遍历，无需搬迁数据即可实现多跳与最短路径式检索。
基于嵌入的语义搜索与稀疏、全文匹配相结合，兼顾语义与精确词条的查询需求。
仪表盘演练场、用于导入与配置的 CLI，以及强类型 Python SDK，让原型验证到正式上线一气呵成。
内置 RAG 与智能体的 AI 原生 Postgres 后端
每个项目都运行独立隔离的 PostgreSQL 实例，具备行级安全，并配备托管认证、对象存储与实时订阅——没有共享逻辑数据库，也就没有嘈杂邻居风险。
上传 PDF、图片、Office 文件或网址，Powabase 会自动提取、切块、向量化并建立索引。支持 BM25、pgvector、混合检索、多模态索引与重排序模型。
用多个 LLM、知识库和工具定义 ReAct 风格的智能体。运行结果通过 SSE 流式返回，会话保存在你项目的 Postgres 中，敏感工具调用可加入人工审批。
拖拽并连接触发器、条件、智能体、HTTP 调用、代码等积木，组装多步骤工作流，也可让自然语言副驾驶代为设计流程。部署后即可变为 HTTP 端点。
