Do almost everything by speaking with AI
C3POperator is an AI-first platform: a voice agent that integrates with your entire work system and knows the relevant dates and context to make accurate decisions. The database and the scheduler every real phone agent needs are native — not stitched together.
Built-in Data Tables
Your agent reads and writes a real datastore — with a UI and a REST API. No external database to wire up.
Native Scheduling
Resources, weekly hours, blackouts, real availability, conflict detection, and live bookings — built in.
Call transfer
The agent hands the call to a human with full context the moment it matters.
Workflow builder
Design conversation flows visually — or describe the agent you want and let AI generate it.
Grounded in your knowledge
Knowledge-base RAG keeps answers accurate — and it's model-agnostic across 30+ providers.
Telephony + WebRTC
Inbound and outbound calls over Twilio, Telnyx, Plivo, Vonage, and more — or right in the browser.
The ledger
What's native here that's DIY elsewhere
Competitors quote a low headline rate, then pass through LLM, TTS, STT, and telephony separately — often with a monthly platform fee. C3POperator's rate is all-in: one number, everything bundled.
| Capability | C3POperator | Competitors |
|---|---|---|
| All-in flat per-minute price | ✓ NativeOne number — STT + LLM + TTS + orchestration bundled | ✕ Not built-inBase fee + STT/LLM/TTS/telephony passthrough |
| No monthly platform subscription | ✓ Pure usage | ⚠ Integrate-yourselfPlans up to ~$990/mo with capped minutes |
| Built-in Data Tables (real datastore, UI + REST API) | ✓ Native, zero setup | ✕ Not built-inBring-your-own DB via webhooks/tools |

| Silence / stall-recovery watchdog (auto-recovers if the model goes quiet mid-call) | ✓ Built in | ✕ Not a standard feature |
Legend: ✓ native · ⚠ possible but integrate-yourself · ✕ not built-in. To be fair: competitors have large voice libraries and mature marketplaces — this ledger is specifically about what's native here that's DIY there.

FAQ
Questions, answered
How much does an AI voice agent cost per minute?
$0.10 per started minute, all-in — speech-to-text, the language model, text-to-speech, and orchestration are bundled, with no monthly platform fee. Adding a separate logic LLM makes it $0.12 per minute.
Is there a free trial?
Every new account gets $10 in free credits — roughly 100 minutes of calls — so you can build and test before paying anything. After that you top up from $5 at a time, or turn on auto-refill so you never run dry mid-campaign.
Can the AI agent book real appointments?
Yes — the native scheduling engine checks real availability with conflict detection and writes new events directly to the calendar during the call.
Which phone providers are supported?
Twilio, Telnyx, Plivo, Vonage, and more over the telephone network — plus in-browser calls via WebRTC, no phone number required.
Can the agent transfer a call to a human?
Yes — built-in call transfer hands the call to a person with full context the moment it matters.
Do I need my own database?
No — Data Tables are native, with a UI and a REST API, so your agent can read and write real records with zero setup.
How fast can I launch an agent?
Start from one of 40+ ready-made templates — or describe the agent you want and let AI generate it — and deploy the same day.
