How it works
From website to working
phone agent in minutes
-
Website address
tellmachines reads your site and learns your services, opening hours, prices and tone — in about three minutes.
-
Talk to your agent
Get a test call on your phone or talk right in the browser. Ask it anything a customer would ask. You can make adjustments later.
-
Forward your calls
Keep using your existing number. So you do not need to communicate a new number to your customers.
Voice quality first
Talk over it.
It won't mind.
Voice quality is the one thing we refuse to compromise on. Callers can interrupt at any moment — the agent stops mid-word, listens, and picks the conversation back up naturally.
- Genuinely interruptible — no "please wait until the end of this message"
- The agent doesn't just speak English. It switches to the caller's language.
- 22 voices, adjustable speed and a pronunciation dictionary for your product names
- Calls are never recorded as audio — only text transcripts, with retention you control

Hi, I need someone for a leaking— actually, first: are you open on Saturday?
We are — Saturdays from 9 to 1. And that leak sounds urgent. Should I book the next available emergency slot for you?
Yes please, as soon as possible.
