Overview
Watch many YouTube videos at once in an auto-arranging mosaic. Add videos while you browse and watch them all together.
Mosaic lets you watch several YouTube videos at the same time, in a clean grid that arranges itself automatically — perfect for following multiple live sports, news streams, podcasts, or reactions at once. Everything works right inside YouTube. As you browse normally, add any video to your mosaic with one click, then open the grid and watch them all together. FEATURES • Add videos as you browse — a "Mosaic" button appears on every video page; add the one you're watching with a single click. • Add by link — paste any YouTube URL or video ID straight into the grid. • Auto-arranging grid — the layout adapts to how many videos you've added. • Independent audio — each tile has its own mute/unmute, so you can focus the sound on just one while the others stay muted. • "Mute all" / "Unmute all" toggle, plus per-tile remove. • Starts where you are — add the video you're watching and the tile begins at the exact moment you left off. • Open on YouTube at the current time — jump from any tile back to the full page at the right second. • Drag to reorder tiles, without interrupting playback. • Plays embed-restricted videos (such as many live broadcasts) by using the real watch page. • Pauses tiles when you close the grid, so nothing keeps playing in the background. • Remembers your videos between sessions and stays in sync across your YouTube tabs. HOW TO USE 1. Open any YouTube video and click the "Mosaic" button (next to Like / Share) — or use the floating button on any page. 2. Click the Mosaic icon in the top bar (or the toolbar icon) to open the grid. 3. Unmute the tile you want to hear. Press Esc to close. PRIVACY Mosaic does not collect, store, or transmit any personal data. Your list of videos is saved only in your browser. The extension only runs on youtube.com.
