Indexes are vector database folders organizing business data embeddings. They support retrieval augmented generation (RAG) for UiPath generative AI experiences, enabling efficient semantic searches. This helps overcome LLM limitations, reduces hallucinations, and provides AI applications access to specialized, current information.

In the UiPath platform, indexes are supported through the Context Grounding service. To use Context Grounding, you must configure a connection to an LLM, as described in Configuring LLMs for your product.
