What is Vectara?

Vectara is an API platform that lets developers build conversational search features into their applications. It specialises in retrieving relevant information from your data and summarising it in natural language, without making things up. The platform uses grounded generation technology, which means it only creates summaries based on sources it actually finds, reducing the risk of misinformation. Vectara is free to use, making it accessible for startups and small teams as well as larger organisations. You can ask questions about your own data, analyse news and documents, or integrate search into customer-facing products. The company provides documentation, community forums, and Discord support to help developers get started.
