💡 Inspiration

YouTube is the world’s largest golf academy, but with millions of videos, it’s impossible to find the truly "best" advice. Many high-quality lessons are buried under clickbait. I wanted to create a "fair and objective" navigation system that uses AI to filter through the noise and deliver only the highest-quality, step-by-step instruction to golfers.

🚀 What it does

YouTube Digest Golf is a data-driven learning platform that organizes the best of YouTube into a professional training program.

  • Level-Specific Playlists: Curated tracks for Beginner (初級), Intermediate (中級), and Advanced (上級) players.
  • AI-Extracted Highlights: Using Gemini 3.5, the system extracts the exact "lesson core" from long videos. Users can play the most important part with a single click at the driving range.
  • Step-by-Step Training: Each theme is broken down into actionable steps, supported by "Auxiliary Videos" (補助動画) for deeper review.

🛠️ How we built it

  • Research: Used Gemini’s Deep Research capabilities to identify influential golf creators.
  • Data Pipeline: Custom Google Apps Script (GAS) to scrape and organize metadata (titles, likes, comments) for 10,000+ videos.
  • Analysis: Leveraged Gemini API / NotebookLM to analyze the relationship between engagement metrics and instructional quality to extract the "Top 1%" of videos.
  • UX Design: A mobile-first interface optimized for "One-handed operation" during practice sessions.

🧠 Challenges we ran into

The hardest part was "Fairness"—ensuring engagement metrics didn't overshadow true educational value. We refined our Gemini prompts to analyze video descriptions and comments deeply to distinguish between viral entertainment and genuine technical instruction.

🏆 Accomplishments that we're proud of

  • The 1% Filter: Successfully distilled thousands of hours of footage into a structured, objective mastery path.
  • Driving Range Optimization: Transformed YouTube from a "viewing platform" into a practical "training tool" with one-click highlights.

⏩ What's next for YouTube Digest

  • 🎙️ Gemini Live Integration ("AI Caddie Mode"): A hands-free, voice-activated interface using the Gemini Live API. Golfers can navigate steps or replay highlights using voice commands while swinging.
  • 👁️ Multimodal Swing Comparison: Utilizing Gemini’s vision capabilities to compare a user's uploaded swing video directly with pro highlights, providing specific, descriptive feedback for improvement.
  • Scaling Vision: We look forward to scaling this vision through the Google ecosystem to support athletes across all sports.
