Why Call0

Why businesses choose Call0.

Why Call0

More than an AI answering machine.

Call0 does more than pick up. The assistant clarifies the request, hands over to your team when a person is needed, and answers with the same knowledge on WhatsApp, by email and in the website chat.

Live the same day
Enter your website, and Call0 builds the assistant from it. 15 test minutes in the browser, without a credit card or sales call.
Several lines from the first plan
Launch includes 3 concurrent calls, 700 minutes and 1 phone number. Nobody hears a busy tone when two customers call at once.
A person takes over when it matters
Handover to your team with a queue, hold music, opening hours and a callback list. The caller is never left hanging.
Phone, WhatsApp, email and chat in one account
One knowledge base for every channel. You maintain it once, and every assistant answers the same way.
Over 500 integrations
Appointments land in your calendar, requests in your CRM or ticketing system, without manual copying.
Set up in conversation
Agent0 sets up the assistant with you and changes it when you ask. No prompt writing, no flow builder.
