Kata chat · Kata Docs

The chat is the app. Everything Kata can do starts with telling it, in your own words.

Ask anything

"How am I doing this week?", "What should I eat before training?", "Why is my score low?": Kata 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. Kata reads quantities, times and context from natural language: no forms, no database search.

Log a past day

Name the day and it goes there: "yesterday I did legs", "Tuesday I skipped creatine", "took magnesium every evening since the first". Each card shows which day it is for, and a range of days becomes one card per day. Kata never files anything on a day that has not happened yet or is more than a year back, and if it cannot tell which day you meant, it asks in one line instead of guessing.

Logging after midnight

Your day ends when you sleep, not when the clock passes midnight. Something you log after midnight, before you have slept, belongs to that evening. Once you have slept, with a sleep you logged or one synced from a source such as Apple Health or WHOOP, it is the new day. With no sleep data at all, 04:00 is the cutoff. It is one rule, and it holds everywhere in Kata.

In the small hours the app shows which day an entry lands on, and one tap moves it to the other day. Kata says in its reply which day it filed something under, and when it is not sure, it asks. A day you name yourself always wins.

Lock-in cards

When something is worth saving, Kata shows it as a lock-in card: food, weight, water, workouts, activities, supplements, goals, personal trackers, memories, profile changes, moods, concerns, reminders and physique entries all arrive this way. In manual mode nothing is saved until you tap Lock in; in auto mode Kata saves what you tell it right away, and the card says so. Saved the wrong thing? One tap takes it back. The full behavior is in Lock-in cards.

Your stack, your phase and your targets

The chat edits the things that steer the app, not only the log. "Swap ashwagandha for vitamin C" archives one supplement and adds the other in the same slot, and "which I have been taking since Monday" backfills the days in between. "Switch me to Build Muscle" changes your phase, "set my protein to 180 g" or "cap my calories at 2,000" sets the one target every screen then shows, and "make my screen-time limit two hours" edits a tracker. Every one of these arrives as a card you can undo, and a phase switch always waits for your tap, even in auto mode.

Honest confirmations

A reply never claims a save that did not happen. What actually landed is what the card says: if a day could not be read, a supplement is not in your stack, or a save failed, the card says so and nothing changes. The same rule holds out loud in Talk to Kata.

The Kata log

The log icon in the chat header opens the Kata log, in three tabs. Locked in is everything ever saved from the chat, with what, when and from which conversation, to review, edit or remove. Memory is what Kata keeps in mind about you. Concerns are the health matters it follows with you. The lock-in mode switch lives here too.

Memory, and correcting it

Kata 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.

Photos and files

The plus button attaches a photo from the camera or the camera roll, opens the product scanner, or uploads a file: a PDF, Word, Excel, CSV, JSON or text file is read and answered like a message. Photo analysis comes with Kata Plus and Kata Unlimited; see Photos.

Kata 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.
