TrainerAI is a chat coach that runs in Telegram and works from the athlete's intervals.icu data. Given a race and date it builds a full plan with phases up to race day, writes structured sessions into the intervals.icu calendar for delivery to the watch, and adjusts the coming week every Sunday based on what was done. It reads sleep, HRV, resting heart rate and weight, comments on each uploaded session, and messages the athlete first in the morning, after a missed session, weekly and after a race. It covers running, trail, cycling, swimming, triathlon and duathlon, with optional strength. The vendor states pace targets are not exported to the watch and that there is no human coach. Pricing is a monthly subscription with a 14-day free trial.
AI level: Conversational AI coach. An LLM-based coach the athlete talks to in free text; it can explain, negotiate and change the plan, usually on top of a model-driven or rule-based planner. trainerai.icu
