Retrieval-Augmented Generation (RAG) tools/softwares refer to a class of AI software systems used to build, deploy, and manage RAG applications. Their core function is to retrieve information related to the user's question from internal enterprise documents, databases, web pages, knowledge bases, code repositories, business systems, or external trusted data sources before the large language model generates an answer. The retrieval results are then used as context input to the model, making the generated content more accurate, up-to-date, and relevant to the business scenario. It also provides citation traceability, improving the accuracy, timeliness, traceability, and business relevance of the answers. Application scenarios include enterprise knowledge base question answering, intelligent customer service, legal/financial/medical document retrieval, R&D knowledge management, code question answering, sales support, report generation, content summarization, compliance review, education and training, and internal search. Gross profit margin is approximately 45%–80%.
