The same question keeps coming up while the answer sits buried in documents. FastGPT is an open-source knowledge base tool, self-hosted or managed: import documents, split and index them, then chain retrieval, decisions and generation in a workflow and expose it as a chat interface for colleagues or customers. It needs a working model service. Messier documents demand more trial with splitting strategy. Features change quickly, so check the project repository.
What it does
- Document import and automatic splitting build a searchable knowledge base
- Workflow nodes combine retrieval, decisions and generation
- Answers carry quoted passages for checking
- Multi-turn context supports follow-up questions
- Open source and self-hostable, or embedded in your own page
Who it is for
- Product manuals and policies should become a Q and A entry
- Support wants citations in answers to cut back-and-forth
- Internal knowledge is scattered across folders and needs one search
- The Q and A capability must embed in your own web page
How to get started
- Collect real questions as a test set
- Import documents by topic instead of all at once
- Measure hit rate on the test set, then tune split granularity
