RagHost was a developer-focused infrastructure service designed to simplify Retrieval-Augmented Generation (RAG) through straightforward APIs for document embedding, chunking, and streaming Q&A. Instead of wrestling with vector databases and custom orchestration from scratch, engineers could plug RAG capabilities into internal tools and apps with minimal boilerplate.
