Pinecone is a vector database that allows users to search through billions of items and find similar matches to any object in milliseconds. It is a next-generation search solution that can be accessed through an API call.

To use Pinecone, you can create an account and index your data with a few clicks or API calls. After creating an index, you can upsert vector embeddings into the index. Then, you can query your data by providing a vector and retrieve the most similar matches. Pinecone also allows for metadata filtering and namespace partitioning to enhance search capabilities.
