Polygres 總結
Polygres turns Postgres into working memory for AI agents. Retrieve structured rows, connected relationships, semantic matches, and full-text results through one hybrid API. All without a separate vector store, graph database, or sync pipeline. Build grounded agents over the data you already have, with relational, graph, and vector context joined at the source. Use the managed cloud or self-host with our open source components. Polygres is currently free to use, just sign up!

使用對比
如何使用Streamdown？
To use Streamdown, you can install it directly with `npm i streamdown` or via `npx ai-elements add response`. Integrate it into your React application by using the `<Response>` component (if using AI Elements) or the Streamdown component itself to render Markdown content. Additionally, you need to update your Tailwind `globals.css` file to include Streamdown's styles by adding `@source "../node_modules/streamdown/dist/index.js";`.
如何使用Polygres？
Create a Polygres managed instance or install the open-source components on an existing PostgreSQL database. Connect your schema and use the SDK or retrieval API to submit a natural-language query with options such as graph traversal depth, filters, and token limits. Polygres combines relational, graph, vector, and text results into one ranked, token-ready context block that can be passed directly to an AI agent.
