Real-Time Live Captions

Transcribe and translate your streams

AI-powered captions, transcription and translation, built into the same nanoStream API you already use: live, in Replay, and in your VOD archive.

Why it matters

Global Accessibility in Real-Time

nanoStream Live Captions makes every stream instantly accessible: AI-powered captions, transcription and translation appear the moment words are spoken, not seconds or minutes later, right inside the platform you already stream from.

The same captions carry through Replay and into your VOD recording, and come with downloadable transcript and translation files ready for postproduction, PR, stream summaries, and social clips.

That's real-time video that simply works, for everyone watching, live or later.

Key capabilities

Everything accessibility needs, built in.

Real-Time Multilingual Captions & Translation

40+ languages. Viewers everywhere follow along the instant it happens, with no lag between speech and subtitle.

Easy API Integration

Your team ships accessibility without adding a vendor, a console, or a project.

Scales With Your Stream

50 viewers or 50,000. One language or ten. The same quality and speed holds.

Downloadable Transcripts & Translations

One caption pass powers your compliance record, your SEO, and your next social clip, across Replay and VOD. Export as TXT, VTT or SRT.

Add Your Custom AI Engine

Use the built-in engine, or connect your own speech and translation model for specific languages, jargon, or compliance needs.

Live Replay

Captions and translations carry straight into Live Replay, so latecomers watch with the same subtitles as your live audience.
