The coach chat.
The chat is the app. Everything Kata can do starts with telling your coach about it, in your own words.
Ask anything
"How am I doing this week?", "What should I eat before training?", "Why is my score low?": the coach answers with your data in mind: your recovery, your protein, your phase, your history. When outside facts matter, it checks the web and cites its sources.
Log in one sentence
"Weighed 82.4, whey shake after training" becomes two structured entries. The coach reads quantities, times and context from natural language: no forms, no database search.
Lock-in cards
The coach never writes to your data on its own. When something is worth saving, it proposes a lock-in card: food, weight, water, workouts, supplements, goals, memories, profile changes and physique entries all arrive this way. One tap saves. Saved the wrong thing? One tap takes it back. The full behaviour is in Lock-in cards.
The decisions log
Every lock-in is recorded: what was saved, when, and from which conversation. Open it to audit, edit or undo anything. Nothing about your data is ever a mystery.
Memory, and correcting it
The coach keeps a memory of you: your shorthand ("the usual shake"), your equipment, your preferences, your decisions. You can read it, and you can correct it in plain words: say "forget that" or "actually, my shake has 25 g" and the memory updates.
Charts in the chat
Ask for your weight trend, your protein week or your sleep and the chart renders right in the conversation, drawn live from your own numbers.
Jump chips
Replies often carry small chips that jump straight to the right place in the app: the workout player, the water tracker, todays supplements. The chat is also your navigation.
Make it coach the way you like
Tell it. "Be more direct", "keep answers short", "stop suggesting runs": the coach adapts its style and remembers. It also learns your rhythm on its own, week by week. More on that in How it adapts to you.
The coach is deliberately scope-locked to your health. For anything medical it will point you to a professional: that is a feature, not a limitation. See It is AI, not a doctor.
