What it is

Sofa is a Chrome extension that syncs video playback across Netflix, YouTube, Disney+, and other platforms with built-in voice chat and text reactions, letting distributed friends watch together without screen sharing or new accounts. The product is free and prioritizes ease of entry through existing streaming subscriptions.
