AI personal trainer · Text or voice · iOS
Kort is a personal trainer you text. It learns your goals, your equipment, and your bad shoulder, then builds every workout around them. Ask at 6 am or 11 pm and get a session in seconds, adjusted to how you feel today.
A plan built for your body. Someone who knows your history, spots what's off, and adjusts when your shoulder acts up. You've priced it out: $150 an hour, booked days ahead, and the clock is always running.
So you tried the apps. Answered the quiz, got a plan. It looked personalized for about a week.
The “custom” program is the same template everyone gets, with your name on it.
Miss a Tuesday and the whole plan falls apart, then guilt-trips you about it.
Logging every set takes longer than your rest periods.
Ask a question and nobody answers. It's a spreadsheet in a coach costume.
So you quit. Again. Not because you stopped training. You stopped getting anything out of the app.
The problem was never your discipline.
It was the app.
Kort is a coach that lives in your phone. Tell it what you're working with: your goals, your gear, the shoulder you don't trust. Then ask. “What should I do today?” gets you a complete workout in seconds, built from everything it knows about you.
Ask again tomorrow. Ask twice in one day. Ask for a 20-minute version because you're short on time. There's no session limit and no hourly rate.
Mention your knee once and it's remembered. Weeks later, Kort asks how it's doing. You never start from zero.
The bookkeeping handles itself too. Say “did 5x5 squats at 225” and it's logged, like a coach taking notes.
Hands chalky, phone in your bag? Tap the mic and say it.
Hotel gym with two dumbbells? Twenty minutes before work? Knee acting up? Say so, and today's workout works around it. Not week 3 of someone else's program.
Kort brings your profile, your plan, your recent workouts, and your constraints into every conversation. You never have to re-explain yourself.
The moment you need a coach is mid-workout, staring at a taken squat rack. Not Thursday at 4 pm when your session was booked. Kort answers in seconds.
Your plan lives in conversation. Say “I can only train 3 days this week” and it adjusts. Missed Wednesday? Kort doesn't care. It asks what you want to do today and builds from there. Guidance, not enforcement.
Other apps give you a program. Kort gives you a coach.
Mention a workout and it's logged. No forms, no dropdowns, no tapping through menus between sets. Talk about your training the way you'd tell a friend, and the record keeps itself.
Prefer voice? Tap the mic. Ten seconds of talking becomes a logged session.
Tell Kort you're resting, busy, sore, or just not feeling it. It adjusts without judgment. No broken streaks, no red badges, no passive-aggressive notifications. Rest is part of training, and your coach treats it that way.
Your goals, your gear, your history, the knee you babysit. One conversation, not a 40-screen quiz.
Built for you in seconds, from everything Kort knows. Don't like it? Ask for another. There's no limit.
Say what you did and it's logged. Say what changed and the plan adapts. That's the whole workflow.
From the founder
“I train 4 or 5 days a week and I've quit every fitness app I've ever tried. So I built the coach I actually wanted. No forms, no menus. You talk about your training, and your coach keeps up.”
Julian Castro · Founder, Kort
One hour with a trainer costs more than a year of Kort.

No. Kort keeps your full training context, your profile, plan, injury history, and recent workouts, and brings it into every conversation. It logs your training, updates your plan, and checks in on that shoulder from three weeks ago. A free chatbot starts from zero every time and won't notice you've been skipping pull days.
Kort suggests. You decide. It offers options based on your history and how you're feeling today, and you can ignore the suggestion entirely and just tell it what you did. It adapts either way.
Kort covers strength, cardio, mobility, and sport-specific work, and it programs to your goal. Chasing a 500 lb deadlift? It programs like a strength coach. Training for a marathon? It plans like a running coach.
There aren't any. Kort is deliberately not social. It's your private coach. Your training, your coach, nobody else.
Your first week is free. After that, pick a weekly, monthly, or yearly plan in the app. Most months of Kort cost less than a single session with a human trainer. Cancel anytime.
