MarginNote is a PDF tool for in-depth reading and study. Keep PDF highlights linked to mind-map cards, then add those cards to review. MarginNote 5 introduces task-based templates for reading, question practice, and vocabulary. MarginNote has evolved since 2013. The upgrade from MarginNote 4 is free. Your study sets, notes, and purchases remain intact. MARGINNOTE 5: ONE TASK, ONE SETUP • Templates — a template sets the bottom tools, menus, pens, and excerpt colors. The "Standard" template has four modes: Excerpt, Handwrite, Organize, and Recall. Each mode groups tools for that task. • Template Gallery — install official templates in one tap. Some templates include examples to help you get started: – Card Practice: write answers by hand on question cards, check your answers, and focus your next review on questions you haven't mastered yet. AI can split a whole workbook into cards. – Reading Vocabulary: collect words while reading English; an offline dictionary provides base forms, pronunciation, and definitions, and finished cards join review when automatic review is enabled. • Make it yours — the corresponding controls are highlighted as you edit. Find features and settings with Feature Search, and export or share your templates. • Traditional Interface — open the template menu and choose "Traditional Interface" (except on iPhone Duo). SYNC YOU CAN SEE The home screen shows where sync stands. The Sync Center lists notes and original documents separately and tells you when a document is still downloading. Manual sync reports results and offers a protective snapshot. Applying cloud changes also protects local study data. THE CARD AT THE CENTER • Organize excerpts by chapter; for books without a table of contents, AI can build one. • Title Links — notes on concepts you've studied resurface as you read new documents. • Extend — open writing space anywhere on a PDF: inline, in the margin, or folded away. AI AS AN ASSISTANT, NOT A SUBSTITUTE AI Breakdown · Question Extraction · AI TOC · AI OCR card templates · translation · chat. Save any answer as a card, or turn its outline into mind-map branches. Online AI sends task text or images to the service provider used for the request. REVIEW: THINK FIRST, THEN LOOK Use Recall mode to hide and reveal answers in the mind map. Add cards to a review deck for FSRS spaced repetition. Write directly on card snapshots while you review. On iOS/iPadOS/macOS 26+, when Apple Intelligence is enabled and its model is available on a supported device and in a supported region, on-device recall hints work offline without MarginNote credits. THE FULL WORKFLOW PDF, EPUB, Office-to-PDF import (online), video and audio · Zotero, cloud drives and external folders · side-by-side documents · handwriting layers and mind-map backgrounds · mind-map PDF export (structure or card flow) · read aloud · fast OCR WHO IT IS FOR Anyone who rereads material and needs to remember it: medical and law students, exam takers, researchers, language learners, serious readers. ACROSS YOUR DEVICES iPhone, iPad and Mac with one Apple Account; iCloud syncs study sets, notes and review progress. Native Apple Pencil handwriting on iPad. Also adapted for iPhone Duo. ABOUT PURCHASES Free to download. Some features require Pro (one-time unlock) or Max (subscription or one-time unlock). MarginNote Agent requires Max and uses MarginNote credits. Some online AI uses MarginNote credits; external AI is billed by its provider. A Max subscription includes 500 credits/month while active.

Verdict

The call

The clearest difference is ratings volume: MarginNote 5 at 736 against 错题本's 5. MarginNote 5 also leads on rating (4.5 vs 4.2) and update cadence (every 3 weeks vs every 2 months). 错题本's advantage is iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
