Kort is an AI fitness coach you talk to — by text or voice. It remembers everything, logs your workouts automatically, and adapts your plan to how you actually train. No forms. No spreadsheets. Just conversation.
Be first in line when Kort launches on iOS.
Manual logging that takes longer than your rest periods.
Rigid programs that fall apart the moment you skip Tuesday.
AI-generated plans that feel like ChatGPT with a gym logo.
The problem was never your discipline. It was the app.
Kort is a fitness coach that lives in your phone. You talk to it the way you'd talk to a training partner. "Just did 5x5 back squats, felt heavy. Thinking legs again Thursday." That's it. That's logging.
Kort extracts the workout data from your words. Logs it automatically. Updates your history. Adjusts your plan. You don't fill out forms — you have conversations.
"You don't log workouts. You have conversations. Your training history is a byproduct of talking to your coach."
Mention a workout in conversation and Kort logs it. Your history page fills itself.
Your goals, injuries, equipment, preferences — it carries forward. Say "my shoulder's been bothering me" once. Kort adjusts future suggestions.
Say "I can only train 3 days this week" and Kort adjusts. No rigid programs. The plan works for your life.
Hands chalky, phone in your gym bag — just say it. Tap the mic and it's recorded. Faster than any form.
No broken streaks. No passive-aggressive push alerts. Rest is part of training, and Kort treats it that way.

"I train 4–5 days a week and I've quit every fitness app I've ever tried. So I built one that works like I think — no forms, no menus, just talk about what you did and get on with your day."
Julian Castro — Founder, Kort
No. Kort is built with persistent memory, tool use, and your complete training context injected into every conversation. It remembers your shoulder injury from three weeks ago, knows you squatted yesterday, and won't suggest legs today. Generic chatbots start from zero every time.
Kort is a generalist coach covering strength, cardio, mobility, and sport-specific training. If you tell it you're running a marathon, it plans like a running coach. If you're chasing a 500lb deadlift, it programs like a strength coach. It adapts its expertise to your goals.
