ONE ANALYSIS PER VIDEO · ONE STROKE AT A TIME

FROM CHILE TO THE COURT — FOUNDER NOTE

I didn't know if I was doing it right.

I started tennis as an adult and got obsessive about improving. The problem was universal: one lesson a week is not enough — and between sessions most players have no idea if they are practicing well or locking in bad habits.

From Chile, I teamed up with Jonathan, an ITF coach with 20 years on court. The idea: use computer vision and AI to analyze motion frame by frame — what the human eye cannot catch in real time. He brought the technical criteria; I brought the analysis. rakly is what came out — built for players training anywhere.

FREQUENTLY ASKED

What people ask.

What is rakly?

rakly is an AI tennis stroke analysis platform. Film with your phone and get a report with the detected stroke, main error, and an actionable fix — with ITF coaching criteria.

Do I need sensors or a special camera?

No. Just your phone. Film from the side, full stroke in frame, good light.

Which strokes does it analyze?

One stroke per video: forehand, backhand, or serve. That keeps the report focused on one clear pattern.

Does analysis replace a coach?

No. It supports you between lessons: it shows what to watch. An ITF coach validates the product's technical criteria.

What happens to my video?

We use it to generate your report and operate the service. We do not sell it. Details in /en/privacy.

How much does it cost?

Start with one free analysis. Then: 1 token $3.99, 2-pack $5.99, 10-pack $19.99, or 20-pack $34.99 (Stripe, USD). One token = one report + dashboard.

Where do I see my progress?

On play.rakly.app: history, notes, and clips from your analyses.

Does it work for coaches and clubs?

Yes. See the coaches and clubs pages for adding analysis between lessons.
