About Pinecone

Pinecone is a commercial managed vector database used to build semantic search and retrieval-augmented generation applications. Developers store embeddings in an index and query it to find the most relevant content, with search, upsert and rerank operations available through one API.

The vendor now describes an AI knowledge platform made up of a database, a Nexus knowledge engine for agents and a marketplace. Nexus compiles enterprise data into governed knowledge once and serves it through a single query, rather than having an agent run a retrieval loop. Pinecone can be reached through plugins for coding agents such as Claude Code, Cursor, Copilot, Codex and Gemini CLI, as well as MCP and the API. A Bring Your Own Cloud option is generally available, and a cost estimator is provided. Pinecone is proprietary and vendor-hosted, with a free start, demo requests and a pricing page.
