About Cora
Our Mission
We believe everyone deserves a world-class fitness coach. Not just the elite athletes or those who can afford a personal trainer, nutritionist, and recovery specialist. Cora exists to make expert-level coaching accessible to all, powered by AI that actually understands your body.
What Cora Does
Cora is your all-in-one AI fitness coach. It builds personalized training programs, guides your recovery, and helps you dial in your nutrition. No more juggling separate apps for workouts, meal plans, and sleep tracking. Cora brings it all together into one intelligent system that adapts to you every single day.
Training
Personalized workout programs that adapt based on your recovery, progress, and goals.
Recovery
Daily readiness scores powered by your wearable data. Train hard when you are ready, rest when you need it.
Nutrition
AI-powered meal guidance that adjusts to your training load, goals, and dietary preferences.
Connected to Your Body
Cora integrates directly with the wearables you already use. Apple Watch, Whoop, Garmin, Fitbit, and Oura all feed real-time data into Cora, so your coaching is grounded in what your body is actually telling you. Your heart rate, sleep quality, strain, and recovery scores all inform every recommendation Cora makes.
Backed by Y Combinator
PurplePill AI, Inc. is part of the Y Combinator W24 batch. We are building Cora alongside the same network that backed Airbnb, Stripe, and DoorDash. This backing reflects a shared conviction that AI will fundamentally transform how people train, recover, and fuel their bodies.
Our Team
We are a small, focused team of engineers, researchers, and fitness obsessives based in San Francisco. We built Cora because we were tired of generic fitness advice and fragmented tools. We wanted a coach that learns, adapts, and holds you accountable. So we built one.
