WHAT I BUILD / High Creativity + AI + PASSION

A few ideas.
Out in the world.

A talking dachshund. A better mirror. A useful starting point.
Built because I wanted to see what would happen.

01

rosi.GPT

A dachshund to talk to. For silly moments and serious thoughts.

ROSI GPT — Rosi in glasses and a knitted vest

WHY I MADE THIS

Everyone needs someone to talk nonsense with — and someone who listens when it matters.

  • A familiar face for the thoughts you want to say out loud.
  • Speak naturally. Get a reply with a personality.
  • For two minutes of nonsense, or something that matters.

High Creativity
I wanted to talk to my dachshund. Obviously, I took that thought quite far.
AI
A rich personality and real-time voice. Expressive 3D and self-learning are where I want to take her next.
Passion
I’ve always wanted to talk to my dachshund. Now I can.

Public beta. Lasting memory, self-learning and native 3D are still in development.

High Creativity
One question about myself turned into a whole personality rabbit hole.
AI
A rule-based personality score, with an optional AI layer for further reflection.
Passion
I want to build things that make us curious about ourselves.

A tool for reflection, not a clinical assessment.

03

High Creativity
Too many useful prompts to leave scattered across too many chats.
AI
Prompts you can copy and adapt in your own AI tools. A useful starting point, not a magic result.
Passion
I like turning a good idea into something someone else can use.

Public beta. 86 editorial prompts in English and German.

04 / AN OPEN QUESTION

The next one
could start with you.

A problem you keep running into. A tool you wish existed. Something wonderfully specific. That’s usually how the good ones start.
