What is Knowledge Base?

Knowledge Base allows you to upload documents and add URLs that your AI agent can reference during conversations. Using RAG (Retrieval-Augmented Generation), your agent retrieves relevant information and provides accurate, context-aware responses.

​
Multilingual Knowledge Bases

By default, knowledge bases are optimized for English content. If your documents are in non-English languages (Hindi, Spanish, French, etc.) or you need cross-lingual retrieval (e.g., query in English, retrieve from Hindi documents), enable Multilingual language support when creating a knowledge base.
ModeBest for
Default (no selection)English-only documents and queries
MultilingualNon-English documents, mixed-language queries, cross-lingual retrieval
Choose the language support mode before uploading. Existing knowledge bases cannot be switched between default and multilingual — you’ll need to create a new one.
If your agent handles calls in multiple languages using multilingual voice support, pair it with a multilingual knowledge base for consistent cross-lingual performance.

​
Managing Your Knowledge Bases

Your uploaded knowledge bases are displayed in a table with full management capabilities.
