Agency and consultancy figures are their own published estimates for build services, not platform prices: Ciela agency pricing guide (Jan 2026), Softcery cost guide (Jul 2026). PolyAI and Bland figures from their own pages, read November 8, 2026. Even Retell tells agencies to “charge for the build separately, always.”
You don’t build an agent. You write a script.
Other platforms hand you a blank agent: prompts, models, voices and tools to wire up, then weeks of tuning. That’s why people pay someone else to do it.
On Komms you write a script: the questions to ask, the answers you expect, and where each answer goes next. Transfers, lookups in your own systems and booking are steps in the script.
- Build it with the Komms MCP. Connect Komms to Claude, describe the call in plain words, and it builds the script for you to check.
- Test it right away. Run the script before a single real caller hears it.
- Put it live the same day. Change a question, save it, and the next call uses it.
A simple script takes about 10 minutes. A complex one, with branches, lookups and transfers, takes hours, not weeks.

Questions
- How much does it cost to build a voice AI agent?
- Agency pricing guides put one voice AI agent at $1,500 to $5,000 to set up plus $300 to $800 a month, and several agents at $5,000 to $25,000 plus $1,000 to $3,000 a month. On Komms you build the script yourself for no build fee and pay $0.08 a minute, phone call included.
- How long does it take to build a voice AI agent?
- Enterprise rollouts take weeks: PolyAI says about six weeks, and Bland's Enterprise plan follows a 28-day plan. On Komms a simple script takes about 10 minutes and a complex one takes hours, and you can test it and put it live right away.
- What is the difference between building an agent and writing a script?
- With an agent you set up prompts, models, voices and tools, then tune them. With a Komms script you write the questions, the answers you expect and where each answer goes next, so you know what the call will do before it goes live.
- Can I build Komms scripts with Claude?
- Yes. Connect the Komms MCP to Claude, describe the call in plain words, and Claude builds the script for you to check, test and put live.
- Will KX21 build my voice AI agent for me?
- Yes. Send us the proposal you got from an agency or voice AI company, and KX21 will build the same thing on Komms for 50% less than that proposal. Running it is $0.08 a minute, phone call included.
