Vectara represents a huge leap forward in search technology. Offering neural search-as-a-service, the platform provides a complete solution that gives developers API access to the most advanced NLP & AI site-level search in just minutes.

Stewart Butterfield, CEO, Slack Technologies

Most people rely on search to navigate websites and applications, including our product, but the underlying technology has not significantly evolved in decades. By applying cutting-edge neural networks, Vectara is bringing much-needed innovation to improve product search.

Frequently asked questions

How does Vectara work?

Vectara uses LLMs and neural networks to apply complete vector encoding for all indexed content and all queries, allowing for a high efficacy semantic response. Vectara combines native neural indexing for all content, statistical keyword algorithms, and re-rankers to maximize the relevance of results across a wide spectrum of queries and data classes.

Is there a free plan?

Yes, Vectara’s Growth plan is free with a defined query volume that resets every month and storage capacity allocation. Customers who need more queries and / or storage capacity can purchase additional capacity bundles on the Growth plan.

What are the use cases for Vectara?
