What makes it different
AI captions usually live in a browser window, on attendees' phones or inside a video production system. GT Captions draws them straight onto the main screen, over whatever your audience is already looking at.
Subtitles float over PowerPoint, videos, PDFs, web pages or any other application running full screen. No colored box covering your slides, and no second layout to design.
Place a sponsor or event logo on the subtitle overlay. Every sentence on screen also carries your partner's brand: a new, highly visible sponsorship asset for your event.
Use more than one audio source in the same session, such as the mixer feed, a lectern microphone and a backup microphone, without adding an external mixer.
Subtitle a video playing on the presentation PC, or a remote speaker coming through a meeting app on it, straight from the computer's sound. No virtual audio cable to install.
No extra hardware
Putting live subtitles over slides has usually meant extra equipment and a specialist to run it. GT Captions runs on the computer that already drives the screen.
The usual setup
Extra equipment to rent, ship, cable and operate, just for subtitles.
With GT Captions
Nothing extra to rent or ship. After one training session your own team can run it, and AV partners can offer it with the kit they already own.
Who it's for
Run professional-looking multilingual subtitles yourselves. We train your team and rehearse with your content before the event.
Offer live multilingual subtitles as a new service, using the computers and screens you already own. Talk to us about working together.

FAQ
GT Captions is a Windows application from Green Terp that shows live AI captions and translated subtitles on a transparent layer over whatever is on a full-screen display: PowerPoint slides, videos, PDFs, web pages or any other application.
