Live Event Captions & Surtitles
Live Captions & Surtitles Tailored for Your Event
Flexible, browser-powered live captions for conferences, auditorium presentations, broadcast streams, and scripted theatre.
Flexible Display Modes
Versatile Ways to Display Captions
Choose the display arrangement that fits your venue architecture and audience workflow.
Attendee Personal Device Relay (via QR Code)
The simplest and most accessible option. We provide a unique QR code you can display on stage or in programs. Attendees scan it to follow real-time captions directly on their own phone, tablet, or laptop at their seat.
Stage Screens & Venue Displays
Display live captions directly on an auditorium projector, confidence monitor, or side TV with clean, readable, high-contrast formatting that works with your room lighting.
Live Stream Integration (vMix & OBS)
Connect captions directly into your broadcast switcher. With our vMix extension or standard browser source inputs, you get clean, digital on-screen titles without fuzzy desktop screen captures.
Scripted Theatre Surtitles
Experience implementing and cueing scripted surtitles for live theatre, plays, and musical performances, keeping text synchronized with actors' line delivery.
100% Private by Design
Audio processed through Zip Captions stays private. Audio is not saved, stored, or sold. Your presenters, attendees, and discussions remain confidential.

Live Event Captioning & Surtitling FAQ
Why can't we just run automatic speech-to-text for a live theatre play, musical, or scripted ceremony?
Automated speech-to-text struggles in live theatre because actors project dramatically, overlap dialogue, sing over musical accompaniment, and rely on split-second comedic or dramatic timing—a two-second AI lag or misheard word ruins a punchline or spoils a scene. For theatre and scripted shows, we pre-load your script and manually cue surtitles live in real time to match the actors' exact delivery on stage screens or attendee smartphones.
Our conference has 4 breakout rooms running at the same time and no budget to put giant LED caption screens in every room. How do we make all 4 rooms accessible?
That is exactly what our QR Code Attendee Personal Device Relay is built for. Instead of renting extra projectors and screens for every breakout room, we assign each room a static QR code poster at the door and on the presenter's opening slide. Attendees scan the room's QR code with their phone or laptop to read real-time captions right at their seat, with zero app downloads.
What does our venue AV tech actually need to hand you on the day of the event?
Just two things: a clean line-level audio feed of the speaking microphones from the venue soundboard (XLR, 1/4-inch TRS, or USB audio interface—with walk-in music and crowd mics excluded) and a standard power outlet. If you also want captions on a stage monitor or vMix/OBS livestream, we connect via HDMI or local network WebSockets/HTTP in minutes.
What if our keynote speakers use heavy industry acronyms, French/English bilingual switches, or specialized proper nouns?
Before your event, send us your agenda, speaker names, organization acronyms, and slide decks. We configure custom vocabulary lists and language profiles (including English and Canadian French) so proper nouns, sponsor names, and technical terms transcribe accurately.
How quickly do you turn around live event quotes, and what areas do you serve on-site vs. remotely?
We respond within one business day with a clear setup recommendation and transparent quote. We provide on-site event captioning and theatre surtitling across Greater Montreal, Quebec, and Canada, and support virtual or hybrid conference streams worldwide.
