Knowledge Bases

Learn how to upload documents to your agent's knowledge base in PropellerDeck so it can answer questions using your own content.

Knowledge Bases

Your AI agent can be given specialized knowledge by uploading documents directly to its knowledge base. Once uploaded, your agent will automatically reference those documents when answering questions — no need to paste content manually into every message.

Uploading Documents

  1. Click the gear icon (⚙️) in the chat panel to open agent settings.
  2. Scroll to the Knowledge Upload section.
  3. Click Upload and select one or more files from your computer.
  4. Wait for the upload and processing indicator to complete before sending your next message.

Supported File Formats

Your agent's knowledge base accepts the following file types:

  • PDF (.pdf) — ideal for reports, manuals, contracts, and research papers.
  • Excel (.xlsx, .xls) — great for structured data, pricing tables, and spreadsheets.
  • Plain text (.txt) — useful for notes, transcripts, raw data, and simple reference documents.

How It Works

When you upload a document, PropellerDeck breaks it into chunks and converts them into vector embeddings — a mathematical representation that captures meaning. When you ask a question, the platform performs a semantic search across your knowledge base to find the most relevant passages and passes them to your agent as context.

This means your agent can answer questions about specific details buried deep in a long document, even if you never mentioned those details in the conversation.

Managing Uploaded Documents

To remove a document from the knowledge base, return to the Knowledge Upload section in chat settings and click the delete icon next to the file you want to remove.
