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.
