AI Voice Agent Knowledge Base for Real-Time Answers
An AI that actually knows your business.
Give your AI voice agents a private knowledge base built from your PDFs, FAQs, product documentation, websites, and databases. Floo retrieves relevant information in real time during live calls and grounds responses in your approved business content.
Use retrieval-augmented generation (RAG) to give sales, customer support, and service agents source-backed answers without relying only on generic model knowledge.

How AI knowledge retrieval works
How an AI Voice Agent Retrieves Answers From Your Knowledge Base
Voice question to source-cited answer, in <400ms.
Floo uses retrieval-augmented generation to search approved knowledge sources while a voice conversation is happening. Relevant passages are retrieved, passed into the agent's response process, and used to generate an answer grounded in the available source material.
Understand the Caller's Question
Voice query to intent
The AI voice agent converts the spoken request into a query and identifies the information needed to answer it.
Retrieve Relevant Knowledge
Your docs + optional VMR
Floo searches the agent's assigned documents, websites, FAQs, databases, and optional VMR research sources for the most relevant passages.
Generate a Grounded Answer
Source-backed response
The retrieved information is provided to the conversational model so the response is based on approved source content rather than generic model memory alone.
Answer During the Live Call
Speak + retain sources
The AI voice agent speaks the answer to the caller while retaining the supporting source information for review and auditing.
Business knowledge plus optional market research
AI Voice Agents With Business and Market Knowledge
A knowledge layer built from your content plus optional VMR research.

Optional Verified Market Research Knowledge Layer
Optional Verified Market Research Knowledge Layer
Floo lets businesses combine their own private knowledge sources with an optional research layer from Verified Market Research. Growth and Enterprise customers can optionally give eligible Floo agents access to VMR research content alongside their private company knowledge base, so voice agents can draw on product documentation, internal processes, and market information within the same retrieval workflow.
- Healthcare market information- Clinical and healthcare market research where available
- Market sizing- Reference market-sizing data for supported sectors
- Industry trends- Sector trend reports from the VMR library
- Competitor information- Competitor and TAM references for supported industries
What it does
AI Voice Agent Knowledge Base Features
Built for the call, not the demo.
Build an AI Knowledge Base From Your Existing Content
Upload and connect the information your AI voice agents need to answer customer questions. Floo can index documents, websites, support content, and structured data sources and make that information searchable during live conversations.
- PDF, DOCX, Markdown, TXT uploads
- Websites, help centers, Notion, Google Docs
- Postgres, MySQL, and BigQuery connectors
Source-Cited AI Answers
Floo keeps the retrieved source connected to the answer so teams can trace important claims back to the underlying document or paragraph. If the available sources do not contain enough information, Floo can use configurable fallback behavior instead of attempting to answer unsupported questions.
- Source citation on every retrieved answer
- Confidence scoring (high/medium/low)
- Configurable fallback when sources fall short
Private Knowledge Bases for Different AI Agents
Assign different knowledge sources to different voice agents, teams, or brands. A sales agent can access product and competitor information, while a customer support agent can use troubleshooting documentation and policies.
- Per-agent knowledge scoping
- Role-based access control
- Tenant-isolated indexes
