Questions about this service
What is an AI voice agent, in practical terms?+
A production phone agent that answers or places calls, understands the caller, and completes work such as booking, routing, or follow-up, without a round-the-clock call center.
How much does a custom AI voice agent cost?+
KeenCraft prices voice agents as a fixed Statement of Work, not hourly. Cost depends on inbound vs outbound coverage, CRM wiring, and conversation design. You get a written total after a free strategy call, before any code is written.
How long does a fixed-price voice-agent build take?+
A proposal typically lands in 2 to 5 business days. Build time then follows the SOW: a focused inbound agent can be weeks; multi-location or multi-channel systems are staged in QA-gated milestones.
Can KeenCraft build a voice agent for a dental or healthcare office?+
Yes. VoiceCake is a live 24/7 inbound voice AI platform serving dental, healthcare, fitness, and mortgage clients, including real appointments booked by an AI agent rather than a script.
What stack do you use for voice AI?+
Vapi, Retell AI, Twilio, Deepgram, ElevenLabs, LangChain, and LangGraph, with latency and infrastructure tuning so calls feel human instead of robotic.
How is a voice-agent project priced?+
Fixed-price and milestone-gated, like every KeenCraft engagement. Scope, deliverables, and total cost are written down before build starts.
