Other tools Jan has built for his work and design research.
In daily use since 2026
Virvar
Virvar brings documents, project notes, meeting transcripts, email and AI conversations into one searchable workspace on your own hosting. AI assistants can read sources, prepare summaries and save records through the Model Context Protocol.
Tresky records the microphone and computer audio as separate tracks. Whisper transcribes them locally into one transcript with speaker labels. Audio and text stay on your computer. Available for macOS and Windows.
A voxel-based tool for hybridising and morphing three-dimensional models. Jan developed its geometry functionality at Subdigital with lead developer Ján Tóth and developer Ondrej Slinták, in a collaboration with the Slovak Design Center.
A free Grasshopper library for simulating flocking behaviour. Components update each agent’s movement using Reynolds’ rules of separation, alignment and cohesion. The Anemone plug-in passes each simulation step to the next.
