The Knowledge Base lets your voice agents retrieve relevant information from uploaded documents during conversations.

​
How it works

  1. Upload a PDF, DOCX, TXT, or JSON document.
  2. Tig.ai splits and indexes the document into searchable chunks.
  3. Attach the processed document to one or more Start Call or Agent nodes.
  4. During a call, the agent retrieves relevant chunks to answer the caller.

​
Supported file types

Maximum file size: 5 MB.

​
Upload and attach documents

  1. Open Knowledge Base Files in the dashboard.
  2. Click Upload New or drag and drop a file.
  3. Click Upload & Process. Tig.ai automatically chunks and indexes the document.
  4. Open a Start Call or Agent node and select the document under Knowledge Base Documents.
The agent searches only the documents attached to the current node. Attach focused, relevant documents to improve retrieval quality.

​
Best practices

  • Keep documents focused on a single topic.
  • Use clear headings, lists, and short paragraphs.
  • Keep source documents up to date.
  • Attach only the documents relevant to each conversation stage.
