We build tools that help people speak better, move better, and live better. A small lab, a short shelf, and a high bar for what earns a place on your home screen.
Adaptive TDEE coach
Most calorie apps hand you a formula and walk away. Zolt learns your real metabolism from real data: weight trend against logged intake, activity, sleep, recovery. The target you get tomorrow is the one your body earned today.
Your coach, over iMessage
No app to open. Text it a meal and it logs. Ask why the scale moved and it explains, holding your actual data. It checks in weekly, remembers what you told it, and picks a personality you can live with. Also on Telegram and WhatsApp.
AI training
Programs that adapt to your recovery and your calendar, not to an ideal week you never have.
Personal rolodex
The people you know, and the context about them you keep forgetting.
Collection
A curated shelf of the best things people have built as Claude artifacts.
