Comparison
RestOrTrain vs ChatGPT for cycling training
ChatGPT is a brilliant general-purpose AI; RestOrTrain is a cycling coach built around your own training data. The difference comes down to what each one actually knows about you.
Short version: for general cycling knowledge, a generalist AI is genuinely useful. The moment the right answer depends on your numbers, your history, or your specific route, a coach that's already connected to your rides wins.

A blank slate vs a coach that knows you
The biggest difference is memory. With ChatGPT you re-explain yourself in every chat - your FTP, your recent rides, what you're training for. RestOrTrain already knows: your history, your personal records, how you respond to load. So you can ask a vague question and get an answer grounded in your actual riding instead of a generic one. It also connects to Garmin, Strava, Intervals.icu, Wahoo, Hammerhead, and Apple Health, so the data arrives on its own.
When ChatGPT is the right tool
For general cycling questions - what a sweet-spot interval is, how Zone 2 works, how to think about a taper - a generalist AI is a good tool, and we'd never pretend otherwise. The difference shows up the instant the right answer depends on you: your current fitness, how tired you are today, the specific climb on Saturday's route.
