Restream Live Captions & AI Multi-Platform Subtitles

Restream is the platform multistreamers use to broadcast simultaneously to YouTube, Twitch, Facebook Live, LinkedIn Live, X (Twitter), and dozens of niche platforms — one stream, many destinations. The audience reach grows quickly when you broadcast everywhere at once, but so does the language spread of viewers: a multistream might reach English speakers on YouTube, Spanish viewers on Facebook, Portuguese viewers on LinkedIn, and German viewers on X all at the same time. Restream live captions via Live Subtitles solve the language and accessibility gap for that audience. Run it on your producer PC and you get real-time AI captions and translations that you can either keep as a personal monitor or capture into your scene to broadcast to every platform.

How to add live captions to Restream in 3 steps

1. Download Live Subtitles from the Microsoft Store and launch alongside Restream Studio.
2. Pick "System Audio" to caption guest and platform audio, or "Microphone" for your own voice.
3. Start your multistream — captions appear in a floating overlay; capture it as a scene source to broadcast captions to all destinations.

Producer monitor vs. broadcast captions

There are two distinct workflows, and Restream multistreamers benefit from both. As a producer monitor, Live Subtitles gives you a real-time text feed of what guests are saying, so you can spot mispronunciations, fact-check live, prep follow-up questions, and react quickly to off-script moments. As broadcast captions, you can place the Live Subtitles overlay window as a video source in Restream Studio or your encoder of choice, and the captions appear inside the stream output that every platform receives.

This split matters because the right answer is different for different shows. A talk show with international guests might want broadcast captions for accessibility; a debate show might prefer a producer-only monitor; a news roundtable might run both — broadcast English captions for accessibility plus producer-side translations for the host's situational awareness.

Multi-language audience reach

Multistreaming inherently creates a multilingual audience. Live Subtitles' dual subtitle mode shows original speech on top and a translation in any of 50+ target languages below — both live, both captured. For shows that target a specific second-language audience (a US show prioritising Spanish viewers, a UK show prioritising French viewers, a German show prioritising English viewers), this turns the secondary platform's audience from passive viewers into engaged readers who can actually follow the discussion in real time.

Accessibility compliance for serious shows

For brands and organisations broadcasting professional content via Restream — corporate webinars, industry events, sponsor-driven streams — caption availability is a serious compliance topic. Many sponsors now require captions for ad reads, and several jurisdictions are tightening accessibility expectations for live online content. Live Subtitles gives you a captions layer you control, broadcasting to every platform Restream is multistreaming to, without depending on platform-specific caption features that may be inconsistent across destinations.

Works with Restream Studio, encoder workflows, and guest browsers

Live Subtitles is agnostic to how you produce your stream:

• Restream Studio in the browser — captions guest audio playing through your PC.
• Encoder workflows (OBS Studio, Streamlabs, vMix) feeding Restream — captions whatever audio is on your bus.
• Restream's mobile-to-desktop setups — captions audio that arrives at your Windows machine.
• Hybrid pipelines with hardware encoders.
