Pinecone stores and searches through dense vector embeddings using a proprietary ANN index. It also has live index updates and metadata filtering, which you’d expect from any database but is surprisingly hard to find or do with vector indexes.

As you said, common use cases include deduplication and image search, and especially semantic search (text).

Do you happen to know other implementations that allow for live updates and metadata filtering like Pinecone?
