Knowledge Base
Upload documents and web pages so your AI agents can answer from your own data
Knowledge Base
A Knowledge Base is a collection of documents, PDFs, and web pages that your AI agents read before answering a customer. Instead of relying on general AI knowledge, the agent retrieves the most relevant content from your sources and uses it to give accurate, business-specific replies.
Creating a Knowledge Base
- Go to AI Studio → Knowledge tab.
- Click New Knowledge Base.
- Give it a name (e.g. "Product FAQs", "Return Policy", "Technical Docs").
- Click Create.
You can create as many Knowledge Bases as you need. Each one is a separate collection — for example, one for support docs and another for your sales playbook.
Adding Documents
Inside a Knowledge Base, click Add Document and choose a source type:
| Source | Accepted formats |
|---|---|
| File Upload | PDF, .txt, .md |
| Web URL | Any publicly accessible webpage |
After uploading, Sentikko indexes the content automatically. The document status changes to Indexed when it's ready for agents to use. Large files may take a moment.
[!NOTE] Each document you add consumes 1 AI Token from your organization's Knowledge Base capacity. See AI Credits for limits.
Linking a Knowledge Base to an Agent
A Knowledge Base does nothing until you connect it to an agent.
- Open the agent in AI Studio.
- Go to the Knowledge tab.
- Toggle on the Knowledge Base(s) you want the agent to use.
An agent can be linked to multiple Knowledge Bases at once. During a conversation, it searches all linked sources simultaneously.
How Retrieval Works
When a customer sends a message, the agent:
- Converts the message into a semantic search query.
- Searches all linked Knowledge Bases for the most relevant passages.
- Injects those passages as context before generating a reply.
The agent does not read entire documents from top to bottom — it retrieves only the sections most relevant to the question. This keeps responses focused and fast.
Managing Documents
Inside a Knowledge Base you can:
- View all documents with their status (Indexing / Indexed / Failed)
- Delete a document — this permanently removes it and returns the token to your balance
- Re-upload a document if the content has changed (delete the old one first)
[!IMPORTANT] Deleting a document is permanent. The agent will no longer have access to that content as soon as it is removed.
Tips for Better Results
- Keep documents focused. One topic per document is better than one massive file covering everything.
- Use clear headings. The indexer uses document structure to chunk content — well-structured files produce better search results.
- Test after adding. Use the Test tab on your agent to verify it uses the new content correctly.
- Update regularly. If your return policy or pricing changes, delete the old document and upload the new version so the agent stays accurate.
