Find Everything You Are Looking For With LLM-Powered Hybrid Search
The way people search is changing. They ask questions. They use shorthand. They make typos. They use voice to search. Today, users ask big questions and expect amazing results, immediately. Vectara radically changes how developers build conversational AI. Developers who use Vectara do not need to address the complexity of human language from plurals, verb tenses, idioms, synonym lists, pragmatics and language packs to deliver incredibly relevant results. Users ask. Vectara answers.
Built for Developers
We start with the developer experience. Developers love Vectara. The platform provides a complete, but composable search pipeline that is API-addressable at every level. Vectara is LLM-powered search-as-a-service. The platform is highly available with industry-leading low-latency response and horizontal scalability able to service the world’s largest apps and sites. Vectara’s API-based platform enables cross-team collaboration from data engineers to ML teams and application engineers, but can be just as easily deployed by a team of one.
Language Agnostic
Imagine the possibilities when a world of information, regardless of the language it was written in, is available to your users. Vectara provides superior cross-language powered by incredible breakthroughs in neural search. It empowers users to access information in a different language than their query. A scientific paper written in Mandarin or Arabic is instantly retrieved and ready for translation by a user asking for it in German. Shift the focus from keywords in specific languages to ideas and conversations across languages.
Vectara: Hybrid Search and Beyond [PDF]
In the AI era, how people interact with information has changed. Users expect relevant answers to questions in natural language, not a shopping list of hit or miss search results. They expect the best semantic or exact matches regardless of typos, colloquialisms, or context. Additionally, it is Vectara’s mission to remove language as a barrier by allowing cross-language hybrid search that delivers summarized answers in the language of your choice. The internet, mobile, and AI have made information accessible, now Vectara helps you find meaning quickly through the most relevant answers. Get to know Vectara, and if you have a question, just ask.

“Vectara is easy to use, fast, and reliable. The neural reranker is a powerful and useful feature for consistently delivering search results with high relevance from several document types that our customers index on our enterprise wiki. Vectara’s API requires minimal effort to maintain in production and the feature updates have been impressive.”
