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。
自带反馈闭环的相关性引擎
以类 SQL 的单条查询完成语义检索、关键词检索与行为模型的检索、过滤、打分和重排。
融合语义与关键词检索，再按每位用户预测的点击率和互动情况重新排序结果。
机器学习模型基于实时交互信号重新训练，随产品流量增长自动提升排序质量。
直接从 Snowflake、Kafka、BigQuery、Shopify 等数仓、分析工具和事件管道流入数据，无需 ETL。
