AI coach
Kairn, the AI coach that knows your plan
Kairn works from your real data: your plan, your imported workouts, how you feel and your fitness. It suggests concrete adjustments — and nothing changes without your say-so.
A coach you can talk to
Ask your questions as you would a coach: “busy week, can you lighten it?”, “how should I handle my taper?”. Kairn answers from your plan and your latest workouts, not with generic advice.
Adjustments you approve
Fatigue, a missed session, a niggle: Kairn suggests a change to your plan, showing what changes week by week. You accept or decline.
A plan that explains itself
Your plan is built by the Paceo engine, then Kairn writes its strategy and details your key sessions: why this session, how to run it, what to watch for.
Every run analysed
After each imported run, Paceo compares what you ran with what was planned (pace, heart rate zones, duration) and Kairn gives you a clear reading of it.
Health first
Kairn works within safety limits set by the engine: controlled volume progression, protected recovery, alerts when something hurts. It is not a substitute for medical advice.
Paces that stay up to date
A maximal aerobic speed test is placed in your plan when yours is missing or out of date; after each test, Kairn updates it and your target paces follow your progress.
