Pavel Svitek — hands-on CTO, founder, full-stack AI engineer.

I'm a product-oriented CTO, hands-on full-stack AI engineer and founder based in Zurich, Switzerland. With a knack for turning ideas into reality, I help people bring their visions to life. As a serial CTO with a successful startup exit 🦄, I'm driven to redefine the boundaries of products with great UX. I'm currently focused on Generative AI (LLMs)! 🚀

Projects

Product experiments and AI applications I built to solve real problems with clear UX, strong privacy defaults, and measurable outcomes.

WortSchatz - Learn German Vocabulary (in-browser)

Build German vocabulary with a focused, repeatable daily workflow.

What it is

A flashcard-based vocabulary trainer that helps learners progress across 850 German most used words with a dashboard for words learned, mastered, due reviews, accuracy, and streaks.

Why I built it

I built it to make language learning more consistent and measurable. Most learners lose momentum because they do not see progress or they are learning the wrong words. It uses browser's IndexDB to store user progress.

Free Voice Transcription app (using in-browser AI model)

Private speech-to-text that runs locally in your browser.

What it is

A real-time transcription app powered by Whisper Tiny that runs fully on-device after model download, with low-latency transcript updates and one-click export to tools like ChatGPT or Gemini.

Why I built it

I built it to prove that practical AI voice tooling can be private by default. Instead of routing audio through external servers, the app keeps microphone data in the browser session while still feeling fast and useful.
