AI note taker for students that turns lectures, audio, slides, PDFs, and videos into notes and study packs.
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.

Polar Notes (PolarNotes AI) is an AI note-taking tool built for students and teachers that converts lectures and course materials into organized study resources. Users can record or upload a lecture, paste a YouTube link, or import slides and PDFs, and the app automatically transcribes audio when needed and analyzes the content to produce summarized notes, key concepts, section headings, and short overviews. From the same source material it can generate a study pack that includes study guides, flashcards, and assessment questions, and results can be exported to Google Docs or PDF with study sets organized in one place. Polar Notes emphasizes privacy and offline access on iOS, keeping notes stored locally on the device unless the user chooses to back them up or share them, which lets students review notes without an internet connection. It also supports multilingual transcription, making it usable for international students and teachers recording in different languages. The tool is delivered as an iOS app with an accompanying web experience and free online tools, and is aimed at learners who want lecture and document content distilled into exam-ready study material rather than verbatim meeting records. Pricing varies by plan. Check the official website for current pricing.
