Connect your carrier account in two clicks
Phone numbers, SIP trunks, and inbound routing flow through the carrier you already know and trust — your numbers, your billing, unchanged.
Conversations indistinguishable from your best agent.
9278.ai skips the brittle speech-to-text and text-to-speech relay and runs on a single audio-native engine — so your callers hear pauses, emotion, and timing that feel right.
Zero-lag conversations
Native audio-to-audio modeling delivers natural warmth and real-time fluidity. No robotic dead air, no awkward pauses while a transcription pipeline catches up.
Smart interruptions
Customers can talk over the agent at any moment. It stops, listens, and responds the way a real human would — not the way a chatbot pretends to.
Unlimited capacity
Scale from one call to thousands simultaneously. No busy signals, no queue time, no per-seat math.
From idea to live agent in three steps.
No infra to spin up, no models to host. Design, connect, and launch — your first agent is taking calls before lunch.
Design your agent
Pick a voice, write the prompt, set guardrails. Describe the agent in plain English and ship it.
- System prompt + personas
- Guardrails and conversation flow
- Plain-English agent definition
Connect your knowledge
Point the agent at your knowledge base, FAQs, or product docs. It answers from your source of truth, not a generic model.
- RAG over your knowledge base
- Live document sync
- Source citations on every answer
Launch & scale
Plug in your phone number, route inbound or outbound, and go live. Scale from one call to thousands without a queue.
- Phone number routing (inbound + outbound)
- Real-time latency tracking
- Self-hosted control panel

Carrier-grade voice

“Aria handles every inbound after-hours call now. We replaced an offshore answering service inside two weeks and our reply time dropped from 14 minutes to under one.”

VP Operations · Marlowe Realty
“The agent handles objections better than half my SDRs. Real interruptions, real follow-up questions — the prospects don't realize they're talking to AI until we tell them.”
Marcus Chen
Head of Sales · Northwind Solar
“We pointed our business number at 9278 and within a day it was triaging, scheduling, and updating our CRM on its own. The remaining 0.6% are the calls humans should handle anyway.”
Priya Anand
Director of Support · Glide Logistics
“I was quoted 6 months by an enterprise vendor. We had a working voice agent in production by day four — connected to our calendar, CRM, and existing phone number — at an order of magnitude less.”
