Find Everything You Are Looking For With LLM-Powered Search

The way people search is changing. They ask questions. They use shorthand. They make typos. They use voice to search. Today, search users ask big questions and expect amazing results, immediately. Every user wants to be heard and understood. Vectara radically changes how developers manage search. 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.

The Future is Neural Search

At Vectara, we believe the future interfaces for text data will be powered by NLP. Application developers will use well-platformed neural networks to process data in every form, from user generated content and web sites to research papers and legal contracts. Developers will build data features that enable better decision support, provide question answering, improve customer experience, monitor for fraud and abuse and accelerate end-user support, to name just a few neural search applications.

Language Agnostic

Imagine the possibilities when a world of information, regardless of the language it was written in, is available to your users. Vectara is a cross-language search platform, 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.

Try it with Sample Data

“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.”
