Go Live in 15 Minutes

No engineering team required. Upload your knowledge, configure your agent, get a phone number, done.

1

Upload Your Knowledge Base

Drag-and-drop PDFs, Word documents, or paste text. Our RAG pipeline automatically chunks, embeds, and indexes your content into a pgvector knowledge base — tenant-isolated so your data never mixes with others.

2

Configure Your Agent

Set your agent's name, voice, personality, and greeting. Define transfer triggers ("connect me to a human"), fallback messages, and confidence thresholds. Everything is adjustable from the dashboard without code.

3

Get a Phone Number

Provision a dedicated phone number via Telnyx in any country. Point existing numbers to your agent with a simple call forward. Set up outbound campaigns with one click.

4

Watch It Work in Real Time

Monitor every call live on the dashboard — transcripts, latency metrics, sentiment, and RAG context used. Every conversation is stored, searchable, and summarized automatically.

Enterprise Features.
Startup Simplicity.

Every component is built for production. Not a wrapper around a chatbot.

Sub-500ms Latency

Streaming LLM + parallel TTS pipeline. Your agent starts speaking before it finishes generating — using Deepgram Nova for STT and OpenAI streaming for the brain.

🧠

Retrieval-Augmented Generation

Answers come from your documents, not hallucinations. Real-time vector search over your knowledge base grounds every response in facts you've approved.

🗣️

Barge-In Support

Callers can interrupt the agent naturally, just like a human conversation. Audio is cleared instantly and the agent reacts within milliseconds.

🔒

Multi-Tenant Isolation

Every tenant's documents, embeddings, call records, and agent configs are completely isolated. Deploy one platform for hundreds of businesses safely.

📊

Real-Time Analytics

Live dashboard showing latency per stage (STT → LLM → TTS), call outcomes, transfer rates, CSAT scores, and full searchable transcripts.

Everything You Want to Know

Common questions from businesses evaluating AI voice agents — answered honestly.

An AI voice agent is software that answers and makes phone calls autonomously — using speech recognition (STT), a large language model (LLM), and text-to-speech (TTS) to hold natural, real-time conversations without a human on your end. VoiceAgentAI adds Retrieval-Augmented Generation (RAG) so the agent answers from your own business documents, not generic AI knowledge.
Key DifferenceVoiceAgentAI is a fully self-hostable, multi-tenant platform built on open standards. Unlike Retell AI or Bland AI, you own your data, your infrastructure, and your call logs. There are no per-seat pricing surprises — just transparent usage-based billing. You also get built-in GoHighLevel CRM sync, real-time latency dashboards, barge-in support, and sub-500ms response times baked into the core architecture — not bolted on.
Most businesses go live in under 15 minutes. Sign up, upload your documents (PDFs, Word files, or plain text), configure your agent's name and voice, provision a phone number, and you're done. No engineering team or code required.
With Premium voice (ElevenLabs) and sub-500ms latency, the experience is very close to a human conversation. However, we strongly recommend disclosing that callers are speaking to an AI — it builds trust and is legally required in many jurisdictions. The agent's greeting can include this disclosure, which most callers accept readily when the experience is smooth.
VoiceAgentAI uses Deepgram Nova-2 for speech recognition, which supports 30+ languages including English, Spanish, French, German, Portuguese, Hindi, Japanese, Korean, and more. The agent can auto-detect the caller's language and respond accordingly, or you can lock it to a specific language from the dashboard.
You configure a fallback behavior in the dashboard. Options include: playing a custom fallback message, transferring the call to a human agent at a number you specify, or asking the caller to leave a callback request. The agent never fabricates information — if confidence is low it defers gracefully rather than guessing.
All tenant data — documents, embeddings, call recordings, and transcripts — is fully isolated per account and encrypted at rest and in transit. For Healthcare customers, VoiceAgentAI is designed with HIPAA-aware architecture and we offer a Business Associate Agreement (BAA) on Growth and Enterprise plans.
Yes. You can forward your existing number to your VoiceAgentAI number with a simple call-forward rule at your carrier — no porting required. Alternatively, you can port your number in or provision a new local or toll-free number in any supported country directly through the platform.
Billing is usage-based with no hidden fees, powered by Stripe. The Starter plan is free with 100 trial minutes. Growth ($149/mo) includes 2,500 minutes, with overages billed at $0.05/min. Enterprise plans offer custom volume pricing. You pay only for actual call time — never per seat or per agent. Overage charges are shown in real time on your dashboard.
GoHighLevel is natively integrated — contacts sync automatically after every call and you can trigger GHL workflows from call outcomes. For HubSpot, Salesforce, and other CRMs we provide webhook support so you can push call data, transcripts, and outcomes to any endpoint in real time.
TechnicalRAG (Retrieval-Augmented Generation) means the AI searches your own documents to find the answer before responding, rather than relying on the LLM's general training. This eliminates hallucinations and ensures the agent only says things you've approved. VoiceAgentAI uses pgvector for millisecond-fast semantic search across your knowledge base on every single call.
Yes. VoiceAgentAI supports both inbound and outbound calling. Use outbound for appointment reminders, lead follow-ups, payment reminders, satisfaction surveys, and re-engagement campaigns — all triggerable via API or the dashboard with no extra setup.
