Knowledge Base (RAG) — Feed the AI Your Documents

Use Knowledge Base when you have more facts than fit comfortably in a system prompt: product catalogs, policies, FAQs, training manuals, real estate listings, menu items, etc.

Supported sources

• PDF upload
• Paste raw text directly
• Website URL (we crawl and parse the page)
• Google Docs URL (share-link with 'Anyone with the link' set to Viewer)
• Google Sheets URL (same sharing requirement — useful for rate cards, inventory, FAQs in tabular form)

How retrieval works

When a caller asks a question, Voxinity embeds the question, searches your sources for the top 3 most relevant chunks, and injects them into the prompt for that turn only. Result: the AI knows your business deeply without paying for huge prompts.

Adding a source

1. Sub-Account → Knowledge Base → New Source.
2. Pick the source type (PDF, Text, URL, Google Docs, Google Sheets).
3. For Google Docs/Sheets: make sure the document is shared with 'Anyone with the link can view' before pasting the URL.
4. Give it a clear title — the AI sees titles when picking which source to consult.

Per-session cost

$0.005 per session that triggers KB retrieval. A 5-minute call that uses KB twice still bills as one session. Cap retrievals per call in Agent → Tools → Knowledge Base.
