Knowledge Base

A knowledge base is like giving AI adedicated reference book: you put your own documents, notes, and URLs into it, and then when chatting, let AI look through this book to answer your questions.

What can you do with a knowledge base?

Here are a few real-world scenarios:

• Company knowledge assistant: Put product manuals, API docs, and internal standards into it, and when employees ask questions, AI answers automatically
• Personal information manager: Put your work notes from previous years, reading excerpts, and archived emails into it, and ask AI, "In which PPT last year did I mention that analysis framework?"
• Study partner: Put course materials and papers into it, and let AI help you generate questions by chapter and answer your doubts
• Contract/regulation quick lookup: Put laws and contract templates into it, and ask AI about the application of specific clauses

Why use a knowledge base instead of just throwing files at AI?

Limitations of directly uploading files:

• You have to re-upload every time you ask a question, which is cumbersome
• There is a length limit for a single conversation, so long documents can't fit
• Can't be reused across conversations

The knowledge base solves all the above problems: Upload once, then it can be used in any conversation, and it can "precisely extract relevant passages" from a large amount of material to feed to AI.

How to use it?

• First time using it: see Complete Knowledge Base Tutorial
• Want to add images / scanned PDFs: first see Document Preprocessing, so AI can "read" the text in images
• Want to know how to choose an embedding model: see Embedding Model Reference
• Want to know where data is stored: see Knowledge Base Data

and combinations with other capabilities

• Knowledge Base + Assistant: Attach a knowledge base to a certain assistant, and it will specialize in this field
• Knowledge Base + Cherry Agent: Let the Agent check the knowledge base on its own during tasks
• Knowledge Base + Channel: Send an Agent that "knows how to look up company documents" to work in Feishu groups

Recommended first reading Concepts Basics Learn about the relationship between the knowledge base and features such as Agent / MCP.
