Studio > Create Application > Chatbot. Select your model, add a system prompt, publish. Your chatbot gets a public URL and API endpoint.
Knowledge > Create Knowledge. Upload documents, choose chunking strategy, create an app that uses this knowledge base. Now your chatbot answers from your documents.
Studio > Create Application > Agent. Add tools (web search, code interpreter), give it a goal, Dify orchestrates the tool calls.
