Glot
Glot provides live AI translation and captioning for in-person events, including conferences, summits, corporate events, trade shows and training sessions. Organizers connect the room’s audio, such as a mixing-desk feed or microphone, and attendees scan a QR code to follow along in their phone’s browser without installing an app or creating an account. They can read live captions in their chosen language or listen to a translated voice through earphones; captions can also be shown on a room screen. More than 60 languages are included. Custom glossaries help retain names, acronyms and specialist terms. The Voice plan also provides a written session summary. Pricing is per room for up to 300 participants: €40 per hour or €235 per day for Captions, and €99 per hour or €590 per day for Voice. Hour credits are available.

VoxFlux
VoxFlux is a browser-based live-event platform for real-time captions, AI-translated text, and translated audio. Event operators can connect a microphone, USB audio interface, or mixer feed, configure a session in a web dashboard, and send captions or translated text to venue screens, livestreams, relay displays, and other browser-based outputs. For audio translation, organizers create an Audio Room and share a listener link or QR code so attendees can listen on their phones or computers without installing an app. The service supports event workflows such as conferences, corporate meetings, webinars, hybrid productions, broadcasts, and multilingual presentations. It also provides session monitoring, caption display controls, transcript downloads, and pay-as-you-go usage credits for event teams, AV professionals, production companies, and broadcasters.

It is designed for individuals and teams using Zoom, Google Meet, Microsoft Teams, and other meeting software; other participants do not need to install Parley or create an account. Qwen and Doubao translation options are available, with language coverage depending on the selected model and configuration.
