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.

Fast Rekap (also branded FastRekap AI) is an iOS application that records meetings, lectures, and voice memos, transcribes them into text, and instantly generates structured outputs. Beyond a standard transcript, the app produces concise AI summaries that highlight key decisions and action items, and it can automatically convert the captured content into presentation slide decks and visual mind maps, which sets it apart from notetakers that produce only text notes. A smart Q&A feature lets users chat with a transcript and receive context-aware answers based on the meeting content. Notes are saved, searchable, and shareable, with PDF export and automatic email delivery of summaries and full transcripts after each recording. The app supports a wide range of languages (the listing cites support across many languages including Spanish, French, German, Chinese, Japanese, Korean, Arabic, Russian, and Vietnamese). Fast Rekap was first released in September 2025 and is actively updated, available on the Apple App Store for iPhone. It targets professionals, students, and anyone who needs to turn spoken sessions into organized, presentable documentation quickly. Pricing varies by plan. Check the official website for current pricing.
