Training
Sessions, strain and recovery in one place. Kata plans around your phase and your readiness, not a template.
Product
The whole system.
One conversation.
The way you interact is the easy part: you just talk, and it feels simple. Behind that, the tech, the AI and your data do the work. It is daily interaction, coaching and quiet assistance, and underneath sit your nutrition, training, water, sleep, recovery, supplements, trends and charts.
Modules
Everything health, in one form.
Training, food, water, sleep, supplements: everything works toward the same goal. Say it once, and everything knows.
Nutrition
Say what you ate or send a photo of the plate. Protein first, phase targets always in view, no database digging.
Water
A daily target computed from your weight and training load: 35 ml/kg, fresh every morning. Log a glass in three words.
Sleep & recovery
WHOOP sleep stages, HRV and recovery flow straight into your day and shape what Kata asks of you.
Supplements
Morning and evening stacks with one-tap take-all. Streaks that reward showing up, reminders that respect your day.
Trends & charts
Weight, protein, sleep and strain as clean charts, rendered from your own numbers, right inside the chat.
AI Coach
A coach that acts. Not just chats.
Say it, confirm it, logged. Kata never writes to your data on its own: it proposes a lock-in card, you confirm with one tap, and the decision is recorded. Every single one.
- Chat, voice, photo
Type it, speak it, or send a photo of your plate. Replies can be read aloud in a voice you choose.
- Knows all your data
It reads your recovery, training, nutrition, weight and phase before answering, and checks the web when facts matter.
- Lock in, or take it back
Kata proposes, you confirm with one tap. Saved the wrong thing? One tap unsaves it.
I weighed 101.6 and had a whey shake after training.
Good morning. That puts you 0.4 kg under your 7-day average, right on Cut pace. Recovery is at 72%, so today’s push session stands. Two entries ready for you:
Weight · Daily weigh-in101.6kg
SavedNutrition · Post-workoutWhey shake · 30 g protein
Lock-in modes
Manual or auto. You choose.
How much Kata may do on its own is a setting, not a surprise. Switch anytime.
Manual mode
Kata proposes a lock-in card for every entry. Nothing is saved until you confirm it with a tap. Full control, card by card.
Auto mode
Kata saves directly as you talk. Every action still lands in your decisions log, auditable and undoable with one tap.
Your data, on its own
It logs itself. You just look.
After that simple chat, everything you mention is logged for you and turns into charts, details and insights. Discover them, add to them, or adjust them whenever you like. And all of it stays one question away: just ask in the chat, and Kata answers from your own data.
Logged automatically
Say it once and it lands in the right place: weight, meals, water, training, sleep. No forms to keep up with.
Charts and details
Your numbers become clean trends and detail views you can open, explore and adjust at any time.
Just ask
Everything is reachable in the chat. Ask what happened, what changed, or what to do next, and Kata knows.
Physique
See the change. Not just the number.
The scale is one line of the story. Guided progress photos capture the rest: same angles, same light cues, laid side by side so twelve weeks of work become visible in one glance. It starts in the chat: ask for a physique check and the camera guides you through the shots, saved privately on your device.
- Guided anglesFront, side, back: the app frames each shot so every photo compares cleanly.
- Before and afterAny two dates, side by side, next to the weight and protein trends behind them.
- Physique analysisAI reads your progress photos and trends together: coming first to Kata Unlimited.

Kata AI
The private AI at the center of Kata: it logs by conversation and adapts to how you write. Your data stays on your device, and nothing you share is stored on our servers.
In your data
Yours, and built to stay that way.
Everything above runs on data that lives on your phone, not on a server. No ads, no reselling, no exceptions. We only ever know the little it takes to make Kata great for you: no chat history, no access to your personal data, not even for us, and not for anyone else. Only what you ask for leaves your phone, always encrypted, and nothing more.
