WHAT I BUILD / High Creativity + AI + PASSION

A few ideas.
Out in the world.

A talking dachshund. A practice search. A better mirror. A useful prompt.
Built because I wanted to see what would happen.

● MY FOCUS PROJECT01

rosi.dog

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.
Talk to Rosi ↗

High Creativity
I wanted to talk to my dachshund. Obviously, I took that thought quite far.
AI
Voice conversations with a dachshund personality. The current website also lets you rate a conversation and offer feedback.
Passion
I’ve always wanted to talk to my dachshund. Now I can.

A public conversation beta, now under the rosi.dog name. Features continue to evolve with feedback from the people who talk to her.

praxiskaufen.com

A better starting point for buying a practice.

Actual Praxiskaufen website

PRACTICE SEARCH / GERMANY

One search. More of the market.

Practice listings are spread across exchanges, professional bodies and brokers. Praxiskaufen.com brings them together, alongside statutory healthcare seats, so buyers can search by specialty and location.

  • Find medical, dental, psychotherapy, veterinary and physiotherapy practices, as well as pharmacies.
  • Let a personal search agent look for new matching offers.
  • Explore market data, a practice valuation tool and acquisition guides.
  • Put asking prices in context using market data; actual sale prices are not assumed.

The problem
A serious search should not mean checking the same separate websites every day.
The tool
Search, filters, a personal search agent and market information in one place.
The next step
Find relevant offers, compare them and follow through to the original listing.
03

handwerkbörse.com

The next chapter: business succession in the trades.

Actual public Handwerkbörse preview

BUSINESS SUCCESSION / PUBLIC PREVIEW

A business of your own. Already up and running.

The approach behind Praxiskaufen, applied to workshops and skilled trades. Search by trade and region, explore existing businesses and use the valuation tool to get your bearings.

  • Listings from succession exchanges, chambers and trade bodies in one place.
  • From joinery and vehicle repair to bakeries and electrical contractors.
  • The public site is still a draft. Some data is illustrative; further agent functions are planned.

DEEPDIEMER

DEEPDIEMER came first. A personality test, and the beginning of this whole adventure.

DEEPDIEMER — the live product interface

WHY I MADE THIS

The project that started all of this.

  • Explore how you think, decide and connect.
  • Get a clear personality profile you can reflect on.
  • Go a little deeper with optional AI reflection.
Get curious about yourself ↗

Public prototype · v155Public website checked 3 October 2026

High Creativity
I wanted to understand my own wiring. This became my first proper “wait, I can build this” moment with AI.
AI
A rule-based personality score, with an optional AI layer for further reflection.
Passion
The starting point has grown into a personality test, Magic Prompt, Partner Check, Blind Spot Test and Find your Rosi. Still a place for curious humans.

A tool for reflection, not a clinical assessment.

05

RobinPrompt.

Skip the blank prompt. Start with a good question.

RobinPrompt — the live product interface

WHY I MADE THIS

I built this out of boredom. Someone else might have a better use for it.

  • Start with a useful prompt instead of a blank box.
  • Find practical ideas, with steps you can follow.
  • Copy, adapt and use them in your own AI tools.

Public beta · 0.1.12Public website checked 3 October 2026

High Creativity
A prompt-sharing platform seemed like a fun thing to build. So I built it.
AI
Prompts you can copy and adapt in your own AI tools. A useful starting point, not a magic result.
Passion
I don’t actually have a use for it myself. If you do, I’m happy for someone to take it over. Tell Rosi through the pitch page.

Public prototype. Open to someone who would like to take it over.

05 / 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.

Pitch your idea to Rosi ↗No pitch deck. No polished performance. Thirty seconds will do.
