MAUTZI. Technology that listens.

An AI-supported assistance system for residents of care homes. Runs on a tablet and is operated mainly by voice.

Status
Prototype, tested with residents
Role
Co-founder · Technology concept · Data modelling
Period
Since 2025, NBank startup grant in January 2026

The case in 60 seconds

Problem
Care homes leave little time for conversation and activity.
Audience
Residents of care homes.
Team and funding
Founding team with Josephine Schulz, funded by the NBank startup grant.
Key decision
Operation mainly by voice, so that people with little experience of technology can use it too.
Status
Working prototype, tested with residents.
Main limitation
No regular operation yet, so no impact measurement.

What MAUTZI is

MAUTZI is a voice-controlled companion for residents of care homes. An animated cat appears on a tablet, and you simply talk to it. It chats, plays bingo or memory, reminds people of appointments and of drinking, and answers questions about the weather and the news.

The aim is less loneliness and more activity in everyday life, plus relief for nursing staff. The tablet arrives preconfigured and needs no setup on site.

  1. You. Hello MAUTZI, what can we do today?
  2. MAUTZI. Gladly. Would you like a round of bingo, or shall I tell you the weather?
  3. You. Will you remind me to drink?
  4. MAUTZI. I will. I check in every two hours.
  5. You. What is the weather like today?
  6. MAUTZI. It stays dry today, and the sun comes out in the afternoon.
Sample dialogue, translated. MAUTZI speaks German.

Starting point

In care homes there is little time for conversation. Managers and nursing staff described this consistently on site. Digital offerings often fail at touchscreens, menus and small type.

My role

I have been a co-founder of MAUTZI since 2025, together with Josephine Schulz. The idea came to us during our studies, not least through our work at Enactus, our enthusiasm for AI and the contact with our grandparents.

I am responsible for the technology concept, data modelling and further development and helped build the prototype myself. Josephine is responsible for product concept and user experience. In January 2026 the NBank startup grant followed.

Approach

Early on we spoke with managers and nursing staff. The most important feedback was unambiguous. A system only helps if it creates no extra work for staff.

MAUTZI runs as a tablet app in kiosk mode, with an animated cat as the assistant. One button starts the conversation. After that, voice activity detection takes over.

We tested the prototype on site with residents.

Concrete results

A working prototype with free conversation, appointments, weather, news, a media library, voice games such as bingo and memory, and a drink reminder.

My bachelor's thesis modelled four usage scenarios as service blueprints and derived nine design requirements from them.

Learnings

The conversations on site shaped the development. Next up are voice operation throughout, feedback when the network fails and a trial in the daily operation of a care home.

Key insight

Closeness to the people you build for beats any assumption made at a desk. The best interface is the one nobody has to learn.
