NoteLyn AI is an AI note taker and study tool that turns whatever you are learning or discussing into notes you can actually use. Record a lecture or an in-person meeting, upload an audio file, import a PDF or Word document, paste a YouTube or web link, or snap photos of slides, handouts and handwritten notes. NoteLyn transcribes and organizes it into a structured note — headings, key points, definitions and takeaways — with a clear AI summary on top. From one note to every study format Most AI note-taking apps stop at a transcript or a summary. NoteLyn treats your note as the starting point. From the same note you can generate: - Flashcards — turn notes into flashcards without typing a single card - Quizzes — an AI quiz maker that builds practice questions from your own material - Mind map and infographic — see how concepts connect at a glance - Podcast — turn notes or a PDF into an audio recap you can listen to on the go - Meeting minutes and action items — decisions and next steps, shareable with one link - AI chat — ask questions and get answers grounded in your note, not the open web What you can turn into notes - Lecture recording to notes, with a live transcript in the mobile app - Audio to notes: MP3, WAV, M4A, AAC and OGG - PDF to notes and Word to notes, with headings and sections parsed automatically - YouTube video to notes, using the video's captions when available - Web articles to notes - Image to notes: OCR for slides, whiteboards, textbook pages and handwriting (up to 9 photos at once) - Typed text with headings, lists, tables and to-dos How NoteLyn compares - vs Otter.ai and Fireflies.ai: those tools are built around online meetings and meeting bots. NoteLyn is built around the content itself — it works the same way for a lecture, an in-person meeting, a PDF or a YouTube video, and it adds study tools (flashcards, quizzes, mind maps) that meeting transcribers don't focus on. If you need a bot that joins Zoom calls automatically, a meeting assistant fits better; if you record in the room or study from what you captured, NoteLyn does. - vs Google NotebookLM: NotebookLM is a research notebook for asking questions across uploaded sources. NoteLyn is a capture-first note taker: you can record a class on your phone, and each recording becomes a finished note plus study materials in one step. - vs Quizlet and Anki: with flashcard apps you build or import the cards yourself. NoteLyn generates flashcards and quizzes from your lecture, PDF or video automatically. - vs Goodnotes, Notability and Apple Notes: handwriting notebooks are great for writing with a pen, but they don't summarize, transcribe or quiz you. Many students handwrite in class and use NoteLyn to turn recordings, slides and PDFs into study material afterwards. Who it's for College and high school students preparing for exams, online learners taking YouTube courses, researchers reading papers, and professionals who need meeting minutes and action items from in-person meetings, client calls and interviews. One account works across the web app (app.notelyn.com), iOS and Android, so you can record on your phone and review on your laptop. Your content is never used to train third-party models, and deleting your account removes all of your data.

Zoey OS is a voice first AI workspace and it belongs to you. It starts with a question: where do you want to be in a year? Zoey builds you a team of AI companions around your goals, so there is nothing to configure and nothing to learn. You give each one a name, a voice and a job, and speak to them out loud, or type when it suits you. Tell Zoey once and she routes the work to whoever owns it. Companions connect to over 1,000 services so work happens in the tools you already use, run on schedules, and remember what matters with memory you can read and erase. In Zoey OS the agents arrive specialized, and every finished job writes a report showing exactly how it was done. The result is outcomes, not another model to manage.
