Overview
Verba 是由 Weaviate 驱动的开源检索增强生成（RAG）聊天机器人，为用户提供端到端的文档问答解决方案。它结合了最先进的 RAG 技术和 Weaviate 的上下文感知数据库，让用户能够轻松探索数据集、提取见解并与自己的文档进行智能对话。支持本地部署（使用 Ollama 和 HuggingFace）或云端部署（通过 OpenAI、Anthropic、Cohere 等提供商），用户可以根据具体需求选择不同的 RAG 框架、数据类型、分块技术和检索方法。作为社区驱动的项目，Verba 提供了完全可定制的个人助手体验，能够回答文档相关问题、交叉引用多个数据点，并从现有知识库中获得洞察。其用户友好的界面使得非技术用户也能快速上手，而开发者则可以深度定制以满足特定业务需求。
