Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and NoteLyn AI when students converting lectures into structured notes and study flashcards matters most. Run both through a week of actual calls to see which suits your workflow.

AI note-taking app that transcribes meetings and lectures into minutes, summaries, and study materials.
Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.

NoteLyn AI is an AI note-taking application that captures meetings, lectures, and other audio and turns them into structured notes, meeting minutes, and study materials. For meetings, it records audio with speaker diarization, or accepts uploaded files and links to recorded Zoom, Teams, and Google Meet sessions, then produces a timestamped transcript with speaker labels alongside a structured summary that highlights decisions, open questions, main topics, and action items with owners and due dates. It frames meeting output around an explicit decision log so that conclusions and follow-ups remain traceable over time. Beyond meetings, NoteLyn doubles as a learning tool, converting audio, PDFs, links, images, and videos into clear notes and generating flashcards, quizzes, and AI question-and-answer for spaced-repetition study. This dual focus makes it suitable for both professionals documenting client calls, standups, and project reviews and students working through lectures and research. NoteLyn supports multiple languages and is available on iOS, Android, and the web, with note export and sharing options. Pricing varies by plan. Check the official website for current pricing.
