What I've built with AI

Everything on this page was built since spring 2025, with AI as the main tool from brief to deployment. Some projects have been running for months; others were done in an afternoon. Both are why I can tell you what AI can build, how long it takes, and where a person is still needed.

Transparence — an encyclopedia written by AI agents

Five AI agents read Czech public sources around the clock — the register of public contracts, the business register, donations to political parties, subsidies, the state budget and the news — and write and update, on their own, a Czech-language encyclopedia of who is connected to whom.

Every page, every link and every source is stored as a versioned file, so for every fact you can trace where it came from and when it changed.

What it shows

How to build agents that work unsupervised for months, not minutes — dividing work between them, a watched budget, quality checks, and automatic rollback of any change that fails them. The same pattern fits company knowledge bases, research, or tracking contracts and suppliers.

Floweo — record your course piece by piece

A tool for people who make online courses. A lesson isn't one long page but a tree of short pieces you can rearrange at any time.

You record straight from each piece: if you misspeak, you re-record that one piece, not the whole hour-long lesson. And you can change the order after recording without re-recording anything else.

What it shows

A full product cycle with AI — from the first prototype, through keyboard-only editing, to recording and managing clips, deployed in the cloud and in real use.

Quick tools

An idea in the morning, an app by the afternoon.

Not everything has to be a product. I built these because I needed them myself, and with AI that was faster than finding something ready-made.

Scales and chords practice

A game for pianists. It shows, say, F♯ harmonic minor or Cmaj7, starts a timer, and you play the right notes — on the on-screen keyboard or a real piano connected to your computer. What you get wrong or play slowly comes up more often.

Built in one day, about two hours of work · 360 exercises at three levels · works with a digital piano

Alphabet tracker for improv

Built after an improv show. One of the games tracks which letters of the alphabet have already been used, and nobody can hold that in their head mid-scene.

Deliberately simple: 26 letters, tap to mark one used, one button to start over. Works on a phone, even offline.

First version online in 17 minutes, finished in an hour

Songbook

A songbook for musicians: lyrics with chords, auto-scroll while you play, one-tap transposition by a semitone, adjustable text size, and full-screen mode for playing from a tablet. Works offline.

The whole app, from its first version in February 2025, was written by AI.
