Human and AI transcription, captions and meeting notes
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.

Rev is a well-known transcription and captioning service that offers both automated (AI) and human-generated transcripts, giving users a choice between speed and maximum accuracy. It is widely used to transcribe recorded meetings, interviews, podcasts, and videos, and it also provides captions and subtitles for video content. In addition to file-based transcription, Rev offers an AI notetaker that can join and summarize meetings, extending its core transcription expertise into the live meeting-assistant space. Users can edit transcripts, search content, and export in various formats, and the human-transcription option is valued when near-perfect accuracy is required, such as for legal, media, or research use. Because it spans automated and human services, Rev appeals to a broad audience — from individuals needing a quick transcript to organizations that require verified, high-accuracy text. It is often chosen when transcription quality and reliable turnaround matter as much as automation. Platforms: Web / upload audio and video / meeting notetaker. Integrations: Zapier.
