Shortlist Boostlingo when adding live ai-translated captions to a webinar or virtual meeting matters most, and DubTab when watching international livestreams, webinars or videos with instant translated subtitles matters most. Run both through a week of actual calls to see which suits your workflow.

Boostlingo is a language-access company whose product suite spans interpreter scheduling, on-site interpretation, remote video and phone interpretation, on-demand interpreter access, and AI-powered live captioning and translation. Its AI Pro engine provides transcription, live translation, and video captioning for meetings, events, and webinars, and the Boostlingo Events offering delivers continuous AI-translated captions for onsite, hybrid, and virtual sessions. Attendees can access live AI captions through a shared link or QR code without downloading anything, with captions appearing in their selected language in real time, and organizers can set default languages and enable automatic translation so the system streams translated captions throughout a session without manual switching. The platform supports a large number of languages and thousands of language pairs and integrates with major video-conferencing platforms including Zoom, Microsoft Teams, and Webex, as well as in-person and hybrid event setups. Boostlingo continues to expand its AI capabilities, including a more recent AI Interpreter that joins its AI captions and translations features. The product is actively operating in 2025/2026 and is well suited to event organizers, enterprises, and language-service providers that need scalable multilingual captioning and translation across both AI and human interpretation workflows. Pricing varies by plan. Check the official website for current pricing.

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.
