Multi-sport, Apple Silicon, local-first

Local Sports Intelligence.

Mac. Camera. Action.

Point a phone at volleyball, tennis, badminton, pickleball, or table tennis. Your Mac watches the play, finds the structure, and turns messy footage into something you can replay, review, or coach from.

Problem

Game footage exists. Usable evidence usually does not.

Parents, coaches, and small venues already record games on phones. The missing layer is local structure: who is in frame, what changed over time, and which moments deserve replay, coaching, or review.
How it works

A phone records. A Mac helps review the game.

Starts without a selected sport, gathers visual evidence, then locks a sport with a rationale.

Local artifacts

Writes overlay videos, summaries, stills, and frame logs next to the source clip.

Review loop

Reviewers mark wrong sport, bad overlay, correct, and demo-worthy outputs.

Private by default

The live capture and review console run from the Mac. The public site only shows safe demo assets.

Demo

See game clips become overlays and review moments.

The demo page shows public-safe clips with overlay renders and review-ready moments.

Why it matters

Amateur sports are messy.

A real gym has bad angles, benches, siblings, spectators, scoreboards, and more than one activity in frame. RefereAI is built for that reality: observe first, explain what changed, and let a human correct the system.
What ships

Not just boxes.

Future state

Next: richer identity, score, and room awareness.

Player and team identity

Cleaner team colors, track continuity, roles, refs, and spectators.

Score confidence

OCR plus rally state so visible scoreboards do not produce noisy score changes.

Multi-camera venue

Blend official corner phones and parent guest phones into one private room view.

Better review loop

Use reviewer feedback to prioritize re-renders, demos, and model comparisons.
