Knowledge Base for AI Voice Agents

Build a RAG-powered knowledge base to give your voice agents access to company documents, FAQs, product info, and website content

Knowledge Base for AI Voice Agents

Give your AI voice agents instant access to company information using RAG (Retrieval-Augmented Generation). Upload documents, crawl websites, and let your agents answer questions with accurate, up-to-date information.

Get started: Open the Knowledge Base in the Edesy Platform to create your first knowledge base.

Why Use a Knowledge Base?

Without a knowledge base, your AI agent only knows what's in its training data. With a knowledge base:

Without Knowledge Base With Knowledge Base
Generic responses Company-specific answers
Outdated information Real-time updated content
Can't answer product questions Accurate product details
No access to policies Instant policy lookup

Key Features

  • Multiple Content Sources: Upload files (PDF, DOCX, TXT) or crawl websites
  • Automatic Processing: Documents are chunked, embedded, and indexed automatically
  • Semantic Search: Find relevant information based on meaning, not just keywords
  • Real-time Updates: Add or update documents anytime
  • Multi-Agent Support: Share one knowledge base across multiple agents
  • Retry Failed Documents: Automatic error detection with one-click retry

Best Practices

Content Organization

  • One topic per document: Improves retrieval accuracy
  • Clear headings: Helps with chunking
  • Descriptive names: return-policy-2024.pdf not doc1.pdf

Content Quality

Ideal for Knowledge Base:

  • Product specifications and manuals
  • FAQ documents
  • Policy documents (returns, shipping, privacy)
  • Training materials
  • Process guides
  • Pricing information

Not Recommended:

  • Scanned images without OCR
  • Documents with complex tables/charts
  • Very long documents (>50 pages) - split them up
  • Frequently changing content (use web crawling instead)

Performance Tips

  • Keep documents focused and concise
  • Update content regularly
  • Remove outdated documents
  • Monitor RAG performance in call transcripts

Use Cases

Upload your FAQ, return policy, and troubleshooting guides. Your agent can instantly answer:

  • "What's your return policy?"

  • "What's the difference between Pro and Enterprise?"
  • "Do you offer volume discounts?"
  • "What's included in the warranty?"

HR & Internal

Employee handbooks, benefits information, IT policies:

  • "How many vacation days do I have?"
  • "What's the process for expense reimbursement?"
  • "How do I reset my password?"
