Knowledge Overview

Knowledge allows BindAI agents to retrieve information from external sources instead of relying only on the language model’s built-in knowledge.

This enables agents to answer questions using your own documents, manuals, APIs, databases, or business information.

Knowledge is the foundation of Retrieval-Augmented Generation (RAG).

---

What is Knowledge?

Knowledge represents information that exists outside the language model.

Examples include:

• company documentation
• PDF files
• product manuals
• knowledge bases
• internal wikis
• databases
• websites

Instead of memorizing this information, the agent retrieves it when needed.

---

Why Use Knowledge?

Language models have limitations:

• training data becomes outdated
• they do not know your private information
• they cannot access proprietary documentation by default

Knowledge solves these problems by providing relevant information at runtime.

---

Knowledge Architecture

A typical knowledge pipeline looks like this:

User Question

↓

Retriever

↓

Knowledge Source

↓

Relevant Documents

↓

Language Model

↓

Response

The language model generates answers using both the user’s prompt and the retrieved information.

---

Example

Suppose your company has an internal policy document.

User:

What is our vacation policy?

Instead of guessing, the agent retrieves the policy document and answers using its contents.

---

Knowledge Sources

Knowledge can originate from many places.

Common sources include:

• Markdown documents
• PDFs
• Word documents
• databases
• REST APIs
• vector databases
• cloud storage
• custom repositories

BindAI is designed so these sources can be integrated without changing the agent interface.

---

Retrieval

Knowledge is typically retrieved rather than loaded entirely.

Instead of sending hundreds of documents to the model:

Question

↓

Search

↓

Top Matches

↓

Language Model

Only the most relevant information is included in the prompt.

This keeps prompts efficient and improves response quality.

---

Knowledge vs Memory

Knowledge and Memory serve different purposes.

Knowledge	Memory
External information	Conversation history
Usually shared	Usually user-specific
Mostly static	Continuously updated
Documents and data	Previous interactions

Use Knowledge to answer factual questions.

Use Memory to remember previous conversations.

---

Knowledge vs Variables

Workflow variables exist only during execution.

Knowledge exists independently of any workflow.

Workflow Variables	Knowledge
Temporary	Persistent
Execution state	External information
Runtime values	Documents and datasets

---

Knowledge in Agents

Agents can be connected to a knowledge source.

Conceptually:

agent.use_knowledge(
    knowledge,
)

When configured, the execution pipeline retrieves relevant information before generating a response.

---

Knowledge in Workflows

Knowledge is also available inside workflows.

Workflow nodes can retrieve information before passing it to downstream agents.

---

Common Use Cases

Knowledge is commonly used for:

• customer support assistants
• documentation search
• internal company chatbots
• legal assistants
• product support
• technical manuals
• enterprise knowledge bases

---

Benefits

Using external knowledge provides:

• up-to-date responses
• private information access
• fewer hallucinations
• domain-specific expertise
• improved factual accuracy
• scalable information retrieval

---

Best Practices

• Keep documents well organized.
• Use retrieval instead of loading everything.
• Remove outdated information.
• Separate Knowledge from Memory.
• Use embeddings for semantic search.
• Keep retrieved context concise.

---

Summary

Knowledge allows BindAI agents to answer questions using information that exists outside the language model.

Rather than depending solely on pretrained knowledge, agents retrieve relevant content from external sources and include it in the generation process, enabling accurate, current, and organization-specific responses.
