The fitness coach that actually remembers you.

Kai is a conversational nutrition & training coach. Snap a meal, say what you ate, log a workout — all in one chat. No forms. No barcode scanners. No spreadsheets.

First 100 signups get Pro free for 6 months.

Why Kai

One chat. Everything tracked.

You wouldn't fill out a form to tell a friend what you ate for lunch. So why does every fitness app make you?

💬

Talk like a human

"Just had a chicken bowl and an iced coffee." Kai logs it, computes the macros, and shows what's left for the day.

📸

Snap, don't search

Take a photo of your plate. Kai's vision model identifies the food and estimates portions automatically.

🎙

Talk to your coach

Hold the mic. Say your meal, your workout, or how you feel. Kai transcribes and responds in context.

🧠

Memory that lasts

Tell Kai once that you hate broccoli, train MWF mornings, or have a tweaky knee. It remembers — for good.

📈

Adaptive targets

Your weight trend doesn't match your goal? Kai proposes calorie adjustments, not arbitrary number changes.

🏋️

Strength & cardio

Log "3x8 bench at 185" and Kai pulls your last session, suggests the next progression, and tracks volume.

How it works

The whole app is one conversation.

1 · Tell Kai about you

A 60-second onboarding. Your goal, current weight, training style, anything Kai should know. Then Kai computes your daily targets.

Hey 👋 I'm Kai. Tell me your goal and I'll set you up.
Lose 8 lbs by August. I train MWF.
Locked in. 2,200 kcal/day · 180g protein. Let's go.

2 · Log without thinking

Type, talk, or snap a photo. Kai figures out the macros and writes them to your day. You stay in the conversation.

just had a chipotle bowl with double chicken
Logged · ~780 kcal · 62g protein. You have 1,150 kcal left today.

3 · Ask, don't dig

"What can I still eat?" "How's my protein this week?" "What did I bench last time?" Kai answers in plain English with the real numbers.

what should I eat for dinner?
You have 1,150 kcal & 70g protein left. Salmon + sweet potato + a side salad would hit it almost exactly.
