STAS gives ChatGPT and Claude your workouts, current plan, goals, and recent reports. The AI works with your real training load, then saves the finished plan to your calendar.

The bot sends your daily plan, shows completed workouts, and lets you add a quick report.


The calendar shows your plan and completed workouts, your rating and report after each session, and progress by week. Your profile keeps goals, rules, and limits so the AI chat remembers them in every conversation.
