Fair use and limits.
Kata AI has generous limits, set so that almost nobody meets them. Here is what they are, and what happens if you ever do.
What counts
Fair use applies only to coach messages, the AI part. Logging, charts, streaks, every data view and everything non-AI is unlimited on every plan, always. One coach message often logs several things at once, so a real day rarely spends more than a handful.
The allowances
| Plan | Coach messages | In practice |
|---|---|---|
| Launch phase | Everything included, free | The full system while we scale. |
| Kata Plus | 500 per month | Around 16 real exchanges a day: more than almost anyone uses. |
| Kata Unlimited | No ceiling | Never think about it. |
What happens at the edge
The coach does not slam a door. If you pass the included usage on a paid plan, it keeps working and, only when it fits naturally, adds one warm line at the end of a reply: you can finish today and, if you want to keep this pace, tomorrow is a good moment to upgrade. It never blocks you and never nags twice in a row.
Usage is an aggregate message count tied to your account for billing. The content of what you said is never part of it. See What the servers do.
