MarginNote 5 vs ReadOS

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.

ReadOS is an all-in-one, desktop-class AI agent workspace for iPad, built around the place serious work often begins: reading. Open a PDF, collect research, inspect evidence, create a report, analyze data, build office files, and continue the task without rebuilding context across separate apps. ReadOS keeps source materials, reading position, selections, files, and project context connected so you can move from understanding to creating. READ WITH CONTEXT • Open PDFs, EPUBs, Markdown, images, local audio and video files, and common office files. • Navigate document structure and page references when the source provides them. • Annotate PDFs, take notes, organize tabs, and export annotated documents. • Build knowledge maps and visual explanations connected to source material. RESEARCH WITH READEX Readex is the AI agent inside ReadOS. When you choose to share content with it, Readex can work with the current document, selected passages, attachments, webpage context, and files in your workspace. Use Readex to: • Summarize and compare source material. • Develop study guides, research plans, and structured notes. • Trace an answer back to relevant pages and context. • Work across multiple files while keeping the research question visible. CREATE, AUTOMATE, AND DELIVER With ReadOS Pro, Readex can help: • Create and edit documents, spreadsheets, and presentations. • Analyze data with Python and JavaScript. • Build charts, tables, interactive visualizations, and knowledge maps. • Browse the web, inspect pages, collect relevant context, and carry out browser tasks. • Transcribe and analyze local audio and video files, extract useful frames, and continue from a playback position. • Carry out multi-step and long-running tasks across available files and tools, with progress you can review and stop. FREE AND PRO ReadOS Free includes library management, local file opening and playback, PDF annotation, notes, navigation, tabs, workspaces, and annotated-PDF export. ReadOS Pro unlocks Readex and advanced AI-assisted work, including browser automation, creation and editing tools, code and data analysis, document and media understanding, and multi-step or long-running tasks. ReadOS Pro is available through Apple In-App Purchase as an auto-renewing annual subscription or a one-time lifetime purchase. ReadOS Pro also requires a supported AI provider account or compatible API connection. Provider subscriptions, usage quotas, and model or API fees are separate and are not included with ReadOS Pro. Availability and results can vary by source format, selected provider or model, network access, and permissions. Start with what you are reading. Keep the context. Build what comes next.
