About

Notju

Features
Read full description

Notju is an AI note taker and your own notebook: what you heard in class, what was on the board, and the PDFs and books you read, in one place. Ju writes it all up as one text, topic by topic. RECORD THE LECTURE, GET A NOTE Record the lecture on your phone or choose an audio file. Notju transcribes it, fixes obvious mishearings and splits it into paragraphs with timestamps. You choose the format: Verbatim, Organized, Summary or Explained. Each part of the note links to its minute in the recording; tap to hear that moment. FROM THE BOARD TO YOUR NOTEBOOK Add photos of the board, book pages and PDFs. Notju reads the text, crops figures and charts and places them in the right part of your note; formulas stay readable. You can see and correct what was read. BOOKS AND LONG PDFS A long document becomes notes chapter by chapter. Before it starts, you choose the chapters and see how much of your weekly usage they take. Chapters open in your notebook as they're ready, with a notification if you want one. JU WRITES YOUR NOTEBOOK Ju reads each new note and writes your notebook as one text, topic by topic: definitions, explanations, formulas, examples and key points, each paragraph linked to the note it came from. Your notebook opens on this text. Mark the topics you've studied; Ju puts the exam and due dates it finds at the top. You can see and undo everything Ju does. ASK JU Ask about your notebooks; Ju answers from your notes and shows its sources. Add files in the chat and say what you want; Ju makes the plan and you start it. EDIT YOUR NOTES Use AI to simplify, shorten, add headings, fix spelling, expand with explanations, translate or add study questions; the suggestion arrives as a separate draft and your note never changes on its own. Write notes yourself, restore earlier versions and share notes as Markdown. A NOTEBOOK FOR EVERY SUBJECT Colorful notebooks for your courses and subjects, with search, on iPhone, iPad and the web with one account. FREE AND PRO Every account with a verified email gets free weekly AI use. Your week starts with your first AI job and renews 7 days later. A note you start finishes even if your use runs out; in a long document, chapters your use doesn't cover start on their own when your week renews. Notebooks, writing notes, reading and search are free on both plans. Notju Pro gives you more weekly AI use and 2 GB of file storage (files up to 300 MB each); a book's chapters are made without waiting for the week to renew, as long as your Pro usage lasts. Pro works on iPhone, iPad and the web with the same account. Notju Pro Monthly: a 1-month, auto-renewing subscription. Payment is charged to your Apple Account when you confirm the purchase. The subscription renews at the same price unless you cancel at least 24 hours before the period ends; the renewal is charged within the last 24 hours of the period. You can manage and cancel your subscription in your App Store account settings. Before any content is sent, you see which service providers it goes to and agree. You can also just keep your sources without AI. AI results can contain mistakes; check important information against your source. Ask your lecturer before you record: some schools and places require consent from everyone whose voice is recorded. A Notju account and an internet connection are required. One AI job can use up to 5 files; documents longer than 40 pages become notes chapter by chapter (up to 2,000 pages a document). Photos and documents can be up to 50 MB each on Free and 300 MB on Pro, and recordings up to 100 MB and 3 hours each. Lectures you record on iPhone and iPad stay on your device; the note and transcript appear on all your devices.
