What does Supavec do?

Supavec is an open-source RAG (Retrieval-Augmented Generation) as a Service platform that lets developers add semantic search capabilities to their applications. You upload documents—text, PDFs, or other supported formats—through a simple REST API, and Supavec converts them into vector embeddings. When users query your system, it returns the most relevant context from your documents with precise citations and source links, all in under 300 milliseconds.

The platform stands out for its developer-friendly approach and production-ready infrastructure. It offers enterprise-grade security with automatic key rotation, multiple SDKs for popular programming languages, and scalable architecture that handles high-volume requests. Unlike proprietary solutions, Supavec is open-source, allowing for community contributions and transparency in how your data is processed.

Software developers building AI applications benefit most from Supavec, particularly those creating customer support systems, internal knowledge bases, or documentation search tools. Real-world use cases include connecting Zendesk or Confluence to provide instant answers to support queries, creating Slack bots that reference HR policies, or building intelligent search bars for technical documentation that return code snippets with proper attribution.
