WORKS WITH THE DATA YOU ALREADY HAVE

WHOOP Garmin Apple Health

Stretching and active movement to help a body bounce back after a workout.

POST-RACE — 12 MIN

RACE DAY
FLUSH

A gentle session to release heavy quads, glutes, and calves after a race.

TRAINING — 8 MIN

LIFT DAY
UNWIND

Shoulders and hips let go after a heavy session in the gym.

SLEEP — 10 MIN

NIGHT
DOWNSHIFT

Slow holds and slower breath to wind the body down for bed.

stretch.ai turns one sentence into a full session, built for that exact body.

Sore lower back. Warm up for tennis. Cool down after leg day. The engine scores movements against the outcome, maps the muscles and joints, and sequences professionally shot clips into one single session.

Experts designed the method and still watch over it: stretching first, with mobility, breathing, and downregulation in their place. Human video and a human voice carry every hold.

An expert-built stretching platform. People say what they need, in their own words, and it builds a routine and coaches them through it with guided video and a human voice. The whole experience can live inside your product.

Each routine is generated for the request, inside a method our experts designed and still monitor. Human coaches shaped it, feedback keeps improving it, and real people demonstrate every move.

It powers pliability, the mobility platform athletes have trained on for a decade. The proof section above carries the measured results from that deployment; 91% of people report improved performance.

A white-label SDK: guided sessions run inside your app, on your brand, with org accounts and your own API keys from day one. One conversation is enough to scope it.

Whatever your users already have. WHOOP, Garmin, and Apple Health signals feed recommendations, and every session adds to what it knows about a body.

Plans depend on your product and your volume. Talk to us and we will shape it together.
