Designing for how families actually live.
JKJang Design has always been about the environments people inhabit — the homes we design, the spaces we help build. Mashti is the extension of that same practice into digital life: a suite of private, family-first AI tools designed to run the household, built with the same care we bring to designing one.
Mashti — a family operating system
(in development)
Mashti is a privacy-first suite of AI tools for family life — coaching, scheduling, memory-keeping, and household coordination — designed around a simple conviction: your family's data should work for your family, not for an advertiser. Each Mashti tool is built to reach you where you are, rather than demanding another app to check.
Bop — personal fitness coaching
(available now, private trial)
Bop is the first Mashti product: a personal AI fitness coach delivered entirely over text message. Bop runs a real coaching intake, builds an evidence-based program around your actual life — your schedule, your equipment, your goals — and adapts as your life changes. A workout each morning, a check-in each afternoon, a weekly review. No app to download, no feed to scroll. Just a coach who shows up.
Your health information stays private — separated, encrypted, and never used for anything but your own coaching.
Bop is currently in a small private trial. Join the sign-up list
