A knowledge base for your AI sales agent: the facts it answers from

The knowledge base holds what the agent should know and never guess: prices, policies, opening hours, objection answers and product details. You add documents, URLs and text. The agent searches them by meaning when it replies, and you choose which agents can see which collection. The persona holds who the agent is, and the knowledge base holds the facts.

What goes where

In the persona

Who the agent writes as and in what tone
What you sell and to whom, as positioning
The goal and the rules for when to stop

In the knowledge base

Prices, plans and discounts
Opening hours, policies and delivery terms
Links and proof points
Answers to objections you have heard

The split is deliberate. A price written into a persona goes stale in every prompt the moment it changes. The same price in the knowledge base is one article to edit.

How it works

1
Add
Documents, URLs or text
Create a collection, add articles, or quick add a URL when you create it.
2
Index
Articles are split into chunks
Each chunk is embedded, so the agent finds an answer by meaning and not by exact words.
3
Link
Choose the agents
A collection is only visible to the agents and personas you link it to. With exactly one active agent, a new collection links to it automatically; otherwise you are told it is not connected yet.
4
Keep current
Rebuilds on change
Adding, editing, deleting or unpublishing an article marks the collection stale and rebuilds the digest the agents use, so a changed price reaches the next reply.

From Claude or ChatGPT

The connector has a `search_knowledge_base` tool that checks what an agent was told about a topic. It matches your text as a literal substring of titles and bodies, not by meaning, so a miss means that wording is absent and not that the topic is uncovered. Articles are edited in the app. See the connector.

Limits

The agent can only answer from what you give it. If a fact is not there, the right behavior is to hand the question to a person, which a needs attention rule can enforce.
Public web pages added by URL must be public. Private and internal addresses are refused.
Sellinger has no published measure of how much a knowledge base improves answers, so none is claimed.

Common questions

Do I need a knowledge base to start?

No. A persona alone works, but price and policy questions then go unanswered or to a person.

Can I add a PDF?

You can add documents, URLs and text. Check the app for the current file types.

Does the agent quote it word for word?

It answers from the matching chunks in its own words. Put exact wording, such as a legal line, in the rules as well.
