How a solo, hands-free session works

No coach. No parent holding the phone. Just your voice and your reps.

1

Pick Athlete, prop your phone up, and start

Choose the Athlete role (or switch to it anytime in Settings). Prop your phone somewhere it can see your full body — a fence, a bucket, a bag works fine. Tap "Start Practice Session." The first time, you'll see a short, plain-language screen explaining what the always-listening microphone does before it turns on.

What's different here: The camera doesn't bind until you actually record a rep — between reps, it's just listening for the wake phrase, not watching. That's deliberate: less battery, less heat, and the mic doing the only work that needs to happen continuously.
2

Say "Hey Coach, record" and take your rep

On-device voice detection hears the phrase, starts the camera, and shows a large, impossible-to-miss "Recording…" indicator — visible from across the room, since you're not standing next to the phone. Take your rep. Recording stops itself automatically once it's captured.

No manual button needed, but it's there: Not every athlete wants to talk to their phone. A manual record button is always on screen too — hands-free is the default experience, never the only option.
3

Hear your feedback — out loud, right away

No screen to read. The AI speaks one encouraging line and one specific correction based on your actual joint angles for that rep — under 25 words, short enough to act on before you even reset your stance.

If the rep wasn't clear: Instead of silence, you'll hear honest, specific guidance — "try stepping back so your whole body is in frame" — so an unclear rep never just feels like the app is broken.
4

Take your next rep whenever you're ready

The microphone re-arms itself automatically after feedback finishes playing. Say "Hey Coach, record" again for the next rep. Keep going until you're done, then end the session — every rep is grouped together and saved to Practice History.

Bring it to your next lesson: Tap into any saved rep afterward to watch it back with the same pose overlay a coach-led session gets — frame by frame, joint by joint.

How a coach-led session works

Four steps. Most coaches complete their first session in under five minutes.

1

Open the app and choose your sport

Select Pitching, Hitting, or Fielding at the top of the screen. Tell the app whether your athlete is left- or right-handed. That's it for setup — the AI automatically knows what to look for based on the sport you chose.

What the AI is looking for: Every sport has a different set of mechanical checkpoints. For pitching, it watches arm path, hip-shoulder separation, and stride mechanics. For hitting, it tracks hip rotation timing, bat path, and head position. For fielding, it monitors footwork, glove-side action, and throwing mechanics.
2

Record with the pose skeleton live on screen

Point your phone at your athlete from a good angle — about 15–20 feet away, at waist height, facing their front side works best. Hit the red record button. You'll immediately see a skeleton overlay appear on your athlete's body in real-time.

What you're seeing: The AI is tracking 33 body checkpoints — nose, eyes, ears, shoulders, elbows, wrists, hips, knees, ankles, and more — simultaneously at 30 times per second. The colored dots on the skeleton show where each checkpoint is being tracked with high confidence.
3

Stop recording and review with pose overlay

Tap the stop button when you have the rep you want to analyze. The session is automatically saved to your library. Tap to open it — you'll see your video playing back with the pose skeleton overlaid. Scrub through frame by frame to see exactly what happened at each moment.

What you can see in the replay: Every rep plays back with the skeleton synced frame-by-frame. Pause at the moment that matters — early heel drop, arm slot at release, weight transfer — and the skeleton shows you exactly where every joint was at that instant.
4

Get your AI coaching cue — then go coach

Tap "Generate AI Coaching Cue." The AI analyzes the pose data from your session and produces one specific, actionable cue — not a data report, not a list of numbers. A real coaching cue you can walk back to your athlete and say out loud.

What makes a good coaching cue: CoachPose AI is powered by advanced AI that understands baseball mechanics. It doesn't just measure angles — it interprets what those angles mean for a pitcher, hitter, or fielder, and tells you what to tell your athlete.

Seeing is believing — with a coach or without one

One of the hardest parts of coaching is getting an athlete to trust the feedback. When you can show them the skeleton — "see how your elbow drops right here, at release?" — they stop arguing and start fixing. And when nobody's there to show it live, the overlay is waiting in Replay afterward.

  • 33 body joints tracked simultaneously — head, torso, arms, legs, even individual fingers
  • Works in any lighting — indoors, outdoors, late afternoon sun or gym fluorescents
  • Left- and right-handed modes — flip the analysis for the athlete's natural side
  • Frame-by-frame scrubbing — pause at any moment in the delivery and see every joint
  • Save and compare sessions — coach-led and solo reps live in the same history

Live pose overlay during recording session

🔊 Spoken — Solo Rep
Athlete Mode

"Nice rep — that back hip is driving well. Your elbow's dropping a little early, try keeping it up through release."

Under 25 words. Spoken aloud within ~3 seconds of the rep ending.
📋 On Screen — Coach Session
Coach Mode

"Weight transfer is textbook — back hip drives through, front knee firms up at contact. Barrel path is slightly downward at approach."

Target: Barrel approach angle through the zone

Same AI, two formats — read on screen, or spoken out loud

Most analytics tools give you numbers. CoachPose AI gives you language. In a coach-led session it's a structured card built for reading together. In Athlete Mode it's a short spoken line built for hearing hands-free, mid-practice.

  • Sport-specific language — not "hip angle 42°" but "your front hip is opening 3 frames too early"
  • Coach mode: tone indicators (Excellent, Improve) plus a target focus area on every cue
  • Athlete mode: one encouraging line, one correction, spoken directly to you — no reading required
  • Powered by leading AI — Claude, OpenAI, or Gemini — your choice of provider

Get better results from day one

Camera angle matters

For pitching and hitting, film from 45° to the front side at waist height. For fielding, directly in front works best. Keep the full body in frame — this matters even more for solo sessions, since nobody's there to fix a bad angle mid-rep.

Consistent lighting helps

Bright, even lighting — outdoors or gym — gives the best skeleton tracking. Harsh backlight (sun directly behind the athlete) can reduce accuracy.

Record multiple reps

More reps give the AI more data to analyze. 5–10 reps gives you a better representation of actual mechanics than a single throw or swing — true whether it's a lesson or a solo session.

Say the phrase clearly

In Athlete Mode, say "Hey Coach, record" at a normal speaking volume from a reasonable distance. If it doesn't catch it the first time, the manual button is always right there as a backup.

Questions people ask first

No. Just your smartphone. CoachPose AI works on any modern iPhone or Android phone with a camera and microphone. No tripod needed — a fence, bucket, or bag works fine for propping it up. No wearables, no sensors, no markers on the athlete.
No. Choose the Athlete role and you get a full hands-free, voice-triggered practice session with spoken feedback — no coach or parent needs to be present or involved. Coaches get a guided, tap-to-record flow built for lessons. Both use the exact same AI analysis underneath.
Yes. Wake-word detection ("Hey Coach") runs entirely on-device — your voice is never recorded or sent anywhere, just listened for locally. Before it ever activates, a clear consent screen explains exactly what's happening. You can switch back to manual, tap-to-record mode anytime.
Yes. CoachPose AI works indoors and outdoors. Standard gym or indoor facility lighting is enough. Brighter is always better for tracking accuracy, but the app handles most typical practice environments.
CoachPose AI uses the same pose estimation technology trusted by research labs and sports scientists worldwide, tracking 33 body points with high confidence. The AI coaching cue is generated by a large language model trained on sports science and biomechanics. It's a coaching aid — not a replacement for a coach's expertise, but a second pair of eyes that never blinks, coach in the room or not.
Yes. CoachPose AI works for athletes of any age and size. The pose estimation adapts to each athlete's body proportions automatically. Catching mechanical habits early — before they're ingrained — makes the biggest difference, which is exactly what solo, coached-every-rep practice is built for.
Your videos stay on your device. CoachPose AI does not upload your recording to any server. When you generate an AI coaching cue, only the pose data (joint positions) — not the video and not your voice — is sent securely to the AI provider. No footage or audio ever leaves your phone.
Yes. Pick a role the first time you open the app, and change it anytime from Settings → Switch Role. All your session history carries over regardless of which role you're using.

Coached every rep — with a coach, or without one

First session takes under five minutes. No hardware to buy, no calibration to run.
