FastGPT
FastGPT is a knowledge-based platform built on the LLMs, offers a comprehensive suite of out-of-the-box capabilities such as data processing, RAG retrieval, and visual AI workflow orchestration, letting you easily develop and deploy complex question-answering systems without the need for extensive setup or configuration.
FastGPT is a platform for building question answering systems over your own knowledge base. You import documents, it handles the indexing and retrieval, and then a visual flow builder lets you decide what happens at each step: which sources to search, when to call a model, what to do with the answer. That flow builder is the part that distinguishes it from simpler document chat tools, because it lets non programmers assemble something closer to an application than a chat box. It is open source and can be self hosted, which is why it turns up in companies that cannot send internal documents to a third party. Expect to spend real time on setup and on tuning how documents are split, which is where the quality of the answers is won or lost.
