在你的 Postgres 上為 AI 代理提供圖、向量與文字檢索
透過一致的介面同時查詢圖、向量、全文與混合檢索,不必把多個系統拼湊在一起。
開源引擎 pgGraph 可跨紀錄沿關係遍歷,不必搬移資料即可實現多跳與最短路徑式檢索。
以嵌入為基礎的語意搜尋結合稀疏、全文比對,兼顧語意與精確詞條的查詢需求。
儀表板遊樂場、用於匯入與設定的 CLI,以及強型別 Python SDK,讓原型驗證到正式上線一氣呵成。

團隊與 AI 代理一起完成工作的 AI 工作空間
將文件、知識庫、專案與資料庫整合進同一個結構化資訊系統,內容成長時依然保持相互關聯。
在頁面內起草、總結、翻譯和回答問題,或建立自訂代理全天候自動化重複性流程。
在 Notion 及已連接應用中即時找到答案,並附上引用來源以便核實。
運用關聯、彙總、檢視以及龐大的範本庫,為 CRM、內容行事曆等各種情境建模。
