Real-time League of Legends
game data on YouTube
A Chrome extension that watches LoL VODs with you — detecting champions, items, and game state in real time, rendered as a native overlay.
Everything happening in the game,
visible at a glance.
Live item & champion detection
ML models analyze video frames in real time, identifying champions, items, ability levels, and gold — even when the streamer's HUD is partially obscured.
Full game scoreboard overlay
A complete scoreboard rendered directly on the video — all 10 players with KDA, items, levels, and gold. Toggle with a single click, just like in-game TAB.
Game time synchronization
Automatic correlation between video timestamps and in-game time. Scrub through the VOD and the overlay updates instantly with the correct game state.
Three steps to
full game visibility.
