FAQ

How does MaxKB compare to RAGFlow or FastGPT? MaxKB is the simplest of the three — it prioritizes ease of use over advanced features. Choose MaxKB if you want a straightforward document Q&A chatbot. Choose RAGFlow or FastGPT if you need advanced chunking strategies, custom workflows, or fine-grained retrieval control.

What makes MaxKB special? MaxKB was built with Chinese language support as a first-class feature. The interface and documentation are fully available in Chinese, and Chinese-language document processing is excellent.

Can I use it without Docker? Currently Docker is the primary installation method. Docker Desktop is free and takes about 5 minutes to install. Once Docker is running, MaxKB installs with a single command.

Do I need my own AI API key? Yes. You need an API key from an AI provider (OpenAI, Anthropic, Google, etc.) or a locally running model via Ollama. MaxKB connects to any OpenAI-compatible API.
