PostgreSQL extension for vector similarity search enabling AI on existing financial databases without separate infrastructure.

Visit Website

pgvector is a PostgreSQL extension that brings vector similarity search directly into the most widely used database in fintech, eliminating the need for a separate vector database. Its ACID compliance makes it the safest choice for financial institutions requiring transactional guarantees on vector data, ensuring that semantic search queries operate within the same transactional boundaries as core financial data. Massive adoption in fintech startups already running PostgreSQL for their core financial data means finance teams can add AI capabilities without new infrastructure. SQL interface keeps the learning curve minimal for existing finance data teams.
