Rattivelo.

A chat assistant for a fictional car service garage: it answers the questions customers ask every day, from prices to tyre storage, and books a service in a few taps, handing over to a person when it isn't sure.

The problem

The phone rings with the same ten questions, all day.

We set ourselves a brief: a busy independent car service garage. In tyre season, the phone rings constantly: how much is a tyre change, are you open on Saturday, do you store tyres, is there a time this week?

Every call takes a mechanic or the service advisor away from the cars, and customers who can't get through in the evening simply book somewhere else.

The idea and approach

Answer the common questions well, book in a few taps, and know when to hand over.

Rattivelo is an invented name. The identity is friendly and technical: a wheel that is also a speech bubble, petrol blue with an amber hub, and a rounded geometric typeface.

The assistant answers only from the garage's own approved information: services, prices, opening hours and policies. Booking is a guided flow of taps, not a free-form conversation. When a question is outside what it knows, it says so and offers a person, instead of guessing.

Key features

What the demo does.

All of it works in the demo, with scripted answers instead of a real AI.

  • Common questions

    Prices, opening hours, tyre storage, electric cars, waiting times and payment, answered in plain words.

  • Booking in a few taps

    Service, day and time as simple choices, with full times shown as unavailable, and a summary before booking.

  • Live appointment panel

    The chosen service, day, time, length and price fill in beside the chat as the customer answers.

  • Type or tap

    Customers can type their own question or tap a suggestion. "Can I book an oil service?" goes straight to the right service.

  • Knows its limits

    If a question is outside what it knows, it says so and offers a person, instead of making something up.

  • Hand-over to a person

    Any time, a customer can ask for a person, and the question goes to the service advisor.

Identity and guardrails

Helpful in seconds, clear about its limits.

Rattivelo's identity, the assistant on the garage's website, and the rules it follows: a fictional garage, designed by Zanarix.

Rounded and technical, like a well-made tool: friendly in a chat, clear on a price list.

Guidelines

  • Amber is the hub: one small highlight, never a background.
  • The assistant speaks plainly and briefly, like a good service advisor.
  • Prices always come with what's included and how long it takes.

On the garage's website

The assistant waits in the corner of every page, and opens full-screen on a phone.

The rules it follows

An assistant is only useful if customers can trust it. These rules are part of the design, not an afterthought.

  • Only approved information

    Answers come from the garage's own services, prices, hours and policies. Nothing else.

  • No guessing

    No diagnoses and no invented prices. "From" prices always say the final price is confirmed first.

  • A person is one tap away

    Customers can ask for a person at any time; unclear questions are handed over automatically.

  • Always labelled

    It introduces itself as an assistant, never as a person.

  • No payment details

    It never asks for card details. Payment happens at the garage.

  • Little data, kept briefly

    Only what a booking needs, and no chat logs kept by default.

Design highlights

A conversation that gets to the point.

  • Taps before typing

    Suggestions under every answer, so most customers never need to type at all.

  • Prices in a table

    Prices appear as a clear list, not a paragraph, with "from" wherever the final price depends on the car.

  • Always labelled

    The assistant says it's an assistant, and the demo says its AI is simulated, inside the chat itself.

  • Made for phones

    Large tap targets and a chat that fits one hand, because most people ask from their phone.

Technology

How we would build it.

The demo runs on scripted answers. For a real garage, we would build it like this:

AI model
A language model from a provider chosen with the client, with EU data handling, answering only from approved content.
Approved knowledge
Services, prices, hours and policies kept in one place the garage edits, so answers stay correct.
Booking integration
Connected to the garage's existing booking system, so free times are always real.
Hand-over
Questions it can't answer go to the service advisor's inbox, with the conversation attached.
Privacy
No chat logs kept by default, and a clear note on what is stored when a booking is made.

What it would do for a business

What an assistant like this is designed to do.

For a real garage, an assistant like this aims to:

  • Answer the everyday questions at any hour, without a phone call.
  • Let customers book in the evening, when the workshop is closed.
  • Free the service advisor for the questions that need a person.
  • Never guess: say clearly when it doesn't know, and hand over.

Intended outcomes, not measured results.
