Adapter

Adapter is a cognition API — a persistent memory and knowledge-graph layer that sits alongside AI models so understanding is already available when agents need answers. Founded by Adam Ghetti and David Bader, Adapter continuously reads and connects a user's data (calendar, contacts, messages, email, conversations) into a living knowledge graph, grounding every response in cited sources and surfacing hidden connections across sources rather than starting each query from scratch. The Adapter API exposes multi-model conversation/completion endpoints, knowledge-graph and memory queries, life-radar events, reminders, multi-channel messaging, reranking, and an OAuth 2.0 + hosted MCP surface (mcp:read) for agent access. Tagline: "Give your model a mind."

Adapter publishes 26 APIs on the APIs.io network, including Adapter API API, assets API, auth API, and 23 more. Tagged areas include Company, Ai, Cognition, Knowledge Graph, and Memory.

Adapter’s developer surface includes authentication, engineering blog, signup flow, support, and 17 more developer resources.
