Polygres summarize
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!

Corsair summarize
Corsair is an open-source integration platform that lets AI products connect to third-party apps via secure, multi-tenant OAuth flows, webhooks, and MCP without building or maintaining the underlying infrastructure. It supports popular services like Gmail, Slack, Notion, HubSpot, and GitHub, with built-in permission controls that require explicit user approval for destructive actions. Developers can self-host the full SDK at no cost or use the managed cloud offering with tiered pricing. Corsair is designed specifically for AI agent workflows, handling auth rotation, schema changes, and error handling across providers automatically.

How to use 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.
How to use Corsair?
Create a Corsair instance, configure your database and encryption key, enable multi-tenancy, and add the integrations you need through plugins. Connect users' third-party accounts through OAuth, define permissions for sensitive actions, and expose integrations to AI agents through typed tools or MCP. You can self-host the SDK or use the managed cloud offering, then build agent workflows, webhooks, triggers, and direct application actions.
