About

I always enjoyed building things. I've built multiple companies, failed with quite a few of them, had a couple of successes, and I never stopped learning. Also, I am part of the hype crew when it comes to AI since it feels like it allows me to build at a completely different scale.

Promptr for AI - The context manager and skills library for marketing teams

LLMs are getting better at memory, but they still can't decide which context matters for each conversation. Promptr for AI is the working memory layer that sits above ChatGPT, Claude, and Gemini: you choose exactly which brand voices, guidelines AND skills to inject for each conversation / thread. And if you work with a team, you can onboard them in minutes. Everyone gets the same full context library inside their LLM of choice, always up to date - at a fraction of the LLM costs.
