Kai is built around one principle: the app should disappear. You talk, it works.
Type or speak what you ate. Kai parses the food, estimates portions, looks up macros (USDA database for whole foods), and writes a structured entry to your day.
Examples Kai handles: "two scrambled eggs and a piece of toast", "chipotle bowl double chicken no rice", "12oz cold brew with oat milk".
Take a photo of your plate. Kai's vision model identifies every food, estimates portions from visual cues, and logs the meal — with a one-line summary of what it saw so you can correct anything.
Works on restaurant plates, home cooking, takeout — anywhere there's a real photo.
Press and hold the mic. Talk to Kai while cooking, walking, or driving (safely). Whisper transcribes; Kai responds in the same conversation.
Tell Kai a stable fact once and it sticks: dietary preferences, training schedule, injuries, life context. Kai uses these to personalize advice over weeks and months — not just one session.
Your starting targets come from a science-based calculation. After a week of weigh-ins, Kai checks your actual trend and proposes adjustments — slow loss, stalled progress, faster than expected — all caught early.
Log strength sessions in plain language. Kai stores the volume and surfaces your prior best set when you're about to lift, so progressive overload is automatic.
Daily history, consecutive-logging streak, weight chart with 7- and 14-day moving averages. Kai surfaces what matters; you don't have to dig.
Kai isn't trying to be a habit. It's trying to give you back the 5 minutes a day other apps steal.
