How Hosiqo compares and tests toolsFinal recommendation
Shortlist DubTab when following zoom, google meet or teams meetings in another language with live captions and dubbing matters most, and Vexa when streaming live, speaker-labeled transcripts into applications matters most. Run both through a week of actual calls to see which suits your workflow.

API-first, open-source meeting transcription platform that deploys bots to capture real-time, speaker-labeled transcripts for developers.
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.

Vexa is an API-first, open-source meeting transcription and intelligence platform aimed primarily at developers and technical teams who want to build meeting features into their own products. Rather than being a polished end-user notetaking app, Vexa provides a developer toolkit: it deploys bots that join meetings via a URL, capture audio, and stream back real-time, speaker-diarized transcripts with low latency over WebSocket, alongside REST interfaces for programmatic bot control. Captured data can be stored and queried for retrieval and export, enabling teams to build live transcription, searchable meeting repositories, or downstream analysis on top of the platform. Vexa currently supports Google Meet and Microsoft Teams, with Zoom support indicated as planned, and its codebase is available on GitHub under an Apache 2.0 license, with both self-hosted and managed cloud deployment options. Because it exposes meeting capture and transcription as programmable infrastructure, Vexa is suited to engineering teams in areas like sales, recruiting, and other domains that need to embed meeting intelligence into custom workflows rather than rely on a standalone consumer app. It is best for developers who want control over how transcripts are captured, stored, and used. Pricing varies by plan. Check the official website for current pricing.
