If you're reading this, you probably already use Intervals.icu. You know your CTL, your ATL, and your TSB. You stare at the Form chart and know exactly how much fatigue you've accumulated.
But when you wake up in the morning feeling crushed from yesterday's threshold ride, a chart doesn't tell you what to do. Should you push through the scheduled VO2 max session? Should you swap it for an endurance ride? Or should you take a rest day?
The endurance market is flooded with static, 12-week PDF plans or rigid apps that don't adapt to life. TrainerRoad is brilliant for cycling, but it assumes you aren't running. Runna is great for running, but it doesn't care if you just did heavy squats. This lack of communication between sports leads to the Concurrent Training Problem: systemic overtraining and injury.
"We built Platyplus because we were tired of being our own head coach, constantly manually adjusting our calendars to balance cycling, running, and strength training."
Platyplus is not just a wrapper around ChatGPT. It is a highly constrained AI engine built on top of the world's most proven sports science logic.
We combined these rulesets into an engine we call the Combination Matrix. It reads your Intervals.icu data, listens to your daily readiness check-in, and acts as the ultimate Head Coach—dynamically rewriting your schedule to ensure you peak exactly when you need to.
