Clevercast is a SaaS platform for multilingual live streaming and accessibility, aimed at organizations broadcasting events, conferences, webinars, and meetings to global audiences. Incoming audio and video are sent from an encoder to Clevercast, which generates AI closed captions described as having high accuracy, including for streams where multiple languages are spoken. From that speech-to-text source it can produce live subtitles in multiple languages, synthetic AI voice translations that viewers select per language, and on-site scrolling transcripts displayed on screens for event attendees. A web interface lets operators correct the AI transcription in real time, improving the resulting captions and translations, and remote human interpreters can also be added for events with strict quality requirements. Streams are delivered via HLS through a global CDN and can be embedded in Clevercast's player or distributed to platforms such as YouTube. It suits enterprises, international bodies, educational institutions, and media companies that need accessible, language-inclusive live broadcasts rather than a personal meeting note-taker.

DubTab is a browser extension for Chrome and Edge that translates spoken audio in real time as it plays in a browser tab. Rather than requiring file uploads or exports, it listens to the audio of whatever tab is playing and produces live translated subtitles on screen, optional bilingual (original plus translation) captions, and low-latency AI voice dubbing that speaks the translation aloud. The vendor states audio stays in the tab and only text segments are processed, and that translations appear with roughly half-a-second latency suitable for live content. It supports 50+ languages and offers voice selection and volume-ducking controls. Because it works on any site with audio, supported contexts include YouTube, Twitch, Netflix, Udemy, Coursera and Bilibili, as well as meeting and conferencing tools such as Zoom, Google Meet and Microsoft Teams, where it can show what participants are saying in real time. It is aimed at online learners, livestream and international-content viewers, and remote meeting participants who need on-the-fly interpretation and captioning.
