Manvex.

AI voice agent · English, Spanish and Catalan

AI voice agent that answers your phone 24/7.

An AI voice agent is a virtual receptionist that answers your business calls in a natural voice around the clock, handles the questions you get every day and books the appointment straight into your Google Calendar. Manvex builds one to fit, with a monthly fee tiered by call volume, and it is usually live in two weeks.

Every call you miss is a customer calling the next name on the list. It happens at lunchtime, it happens while you are with another client, and above all it happens after hours, which is exactly when people have time to call. A voice agent picks that call up, deals with it, and leaves the appointment in your calendar.

From first call to agent live.

About two weeks of work, most of it on our side. Yours is two calls and a round of testing.

  1. 01

    Listen

    What your customers ask, which calls you are losing and when. That defines what the agent is for, and what it is not for.

  2. 02

    Script

    The conversation gets written: how it greets, what it knows about your business, what it can promise and when it hands over to a person.

  3. 03

    Connect

    Phone number, your Google Calendar and the notifications you want after each call all get wired up.

  4. 04

    Test

    You call it, your team calls it, we call it. The script is tuned on real calls before a single customer hears it.

  5. 05

    Live

    The agent goes into production and keeps being refined over the first weeks with real calls.

What your agent costs.

Two parts: the initial setup and a monthly fee that scales with the volume of calls it handles. Both are in the same proposal, fixed in writing.

Agent setup

Quoted per project

Analysis, conversation script, voice, connection to your calendar and your number, testing and go-live.

  • Script written around your business
  • Google Calendar integration
  • Real test calls before launch

Monthly fee

Tiered by call volume

Service, call minutes, script improvements and support. Scales with the volume of calls you handle.

  • Tiers based on monthly calls
  • Script adjustments included
  • Call summaries and metrics

The monthly tier is set from your real call volume and fixed in writing in the proposal. Asking for it is free and commits you to nothing.

Questions about the voice agent.

The first three are, in that order, what everyone asks.

  • How much does an AI voice agent cost in Spain?

    There are two costs: the initial setup and a monthly fee that rises with the volume of calls the agent handles. The exact figure depends on your case and is fixed in the proposal, which is free and arrives within 24 hours. For comparison, it lands well under a part-time person just to cover the phone, and it also answers at 3am.

  • Is an AI voice agent legal in Spain?

    Yes, as long as three things hold: the caller knows from the start that they are talking to an automated system, any call recording is disclosed with consent collected as GDPR requires, and the data is processed on a clear legal basis. Agents are configured that way by default. For the specifics of your sector it is worth reviewing with your own adviser, since a clinic and a workshop do not handle the same data.

  • Can people tell it is an AI?

    You can tell the voice is synthetic if you pay attention, which is why the agent says so up front instead of hiding it. What you cannot tell is a robot: it understands normal speech, copes with interruptions and never makes anyone press one or two. You can hear a simulation of the booking flow in the Agent section of the homepage.

  • What happens when the agent does not know the answer?

    It does not make one up. When a question falls outside what it has been given, it hands the call to a person or takes the details and alerts you to call back. That boundary is decided with you in the script, before the agent answers its first call.

  • Which languages does it speak?

    English, Spanish and Catalan as standard, and it switches language mid-call if the caller does. More languages can be added, and the proposal says plainly whether that changes the price.

  • How long until it is up and running?

    About two weeks from kickoff, covering the analysis, the script, the calendar connection and the testing. The bulk of the work is ours: your side is two calls and a round of testing.

  • Do I have to change my phone number?

    No. The agent can take a new number or receive calls forwarded from the one you already have, whichever suits: after hours only, only when the line is busy, or always. That is decided at go-live.
