Modern RAG solutions combine the speed of large language models with the precision of structured document search, enabling instant, context‑aware answers that feel almost conversational. In this list, we evaluate five top‑tier platforms that excel at powering internal IT support chatbots. Each entry is scored on ease of integration, customization depth, knowledge‑base flexibility, and overall cost‑effectiveness.
