MarginNote 4: AI Notes·MindMap

Description

MarginNote is the PDF study tool for deep readers. One excerpt is a PDF highlight, a mind map node, and a flashcard — one capture, three places. This is the Card Axis architecture, so you stop ferrying content between a PDF reader, a notes app, and a flashcard tool. A decade of iteration. 188K+ App Store ratings.

【Four Featured Mechanics】

▸ Card Axis — One excerpt, three renders. Document highlight, mind map node, and flashcard are the same card seen from three angles.
▸ Title Link — Old notes auto-surface in new documents. When a familiar concept appears in what you're reading, your past annotation lights up on the page.
▸ Extended Note — Long-press anywhere on a PDF to open writing space. No anchored text required; three display modes (inline / margin / collapsed).
▸ Immersive Mode (4.4) — Three-state toggle: Read / Write / Recall. UI folds away. Recall blurs excerpts with Gaussian blur — tap to reveal only after you've actually recalled.

【AI Capabilities (introduced in 4.2)】

AI book breakdown · AI OCR templates · AI translation · AI Q&A · AI flashcard generation
Our stance is AI as assistant, not replacement — every suggestion can be saved as your own thinking node, never thinking for you.

【Apple Intelligence (iOS 26+)】

Recall Mode hints can run on-device via Apple Intelligence — pick "Apple AI" or "cloud LLM" in Settings. With Apple AI selected, three tiers of help — Neighbor Coordinate · Reasoning Prompt · Key Distinction — are generated by Apple Foundation Models right on your device: no network calls, no AI credits used, your notes never leave your device. Even if you've selected cloud LLM, going offline auto-falls back to Apple Intelligence (provided your device supports it) — so libraries, planes, and exam-day silent rooms never break your hint loop.

【Full Workflow】

Fast OCR · Study Sets (PDF / EPUB / video / audio) · direct read from Zotero / cloud drives / USB · 10 mind map styles · book recomposition · dual-document compare · concept maps · handwriting layers

【FSRS Spaced Repetition】

Built on the open-spaced-repetition project's algorithm (paper accepted by ACM SIGKDD; Anki has used FSRS as its default scheduler since v23.10). Push short-term memory into long-term.

【Built For】

Anyone re-reading a single document until it sticks — med school (USMLE / MCAT) · law school (LSAT / bar exam) · grad prep (GRE / GMAT / CFA) · researchers · language learners (IELTS / TOEFL) · serious readers.

【All Apple Platforms】

iPhone + iPad + Mac under one Apple ID. iCloud syncs Study Sets, notes, and review progress. Native Apple Pencil support on iPad.

Nouveautés (v4.4.1)

New/Improvements:
Immersive Mode & Recall Mode Experience Optimization
- Added the hand tool to the handwriting toolbar in Immersive/Recall mode, which can be used to drag the canvas or browse pages.
- The bottom toolbar in Immersive mode can now be collapsed into a three-dot control to reduce interface obstruction.
- Immersive mode now supports Research Browser: You can open the Research Browser panel for document excerpts/mind map cards while in Immersive mode, presented as a floating window, making it easy to look up information while reading.
- Optimized excerpt/handwriting toolbar menus in Immersive mode: Supports adjusting the tool order in the menu bar, keeping it consistent with classic mode, and duplicated tools will now be fully displayed.
- iPhone experience optimization: When opening a study set that hasn't recorded an immersive state for the first time, it now defaults to Immersive mode, significantly improving the small-screen experience without affecting the same study set's settings on iPad and Mac; the document/mind map linked view now supports adjusting the split ratio.
- Added a "Show One-by-One" option in recall mode. When enabled, only one revealed excerpt or mind map card is displayed at a time, making the recall pace more controllable.
- Handwriting is now supported in recall mode.

New "Legacy Features" Settings Section
- Centralized management of toggles for Trash (Legacy), legacy recall mode, legacy handwriting toolbar icons, and more (Settings → Legacy Features). The legacy recall mode is only available in non-immersive mode, and related menus and keyboard shortcuts will be limited accordingly.

Overall Performance & Experience Optimization
- Reduced potential stutter during selection changes while keeping the interface refreshing normally; also optimized stability when handling AI conversation errors.

Fixes:
- Fixed the issue where the eraser shortcut was not working in Immersive mode on Mac, and improved the stability of related shortcuts.
- Fixed the issue where formula styles were not loaded correctly on macOS 26.5.
- Fixed the issue where math formulas in note cards could display abnormally.
- Fixed a display anomaly with the toolbar in Immersive mode.
- Fixed the issue where tapping on a blank area could not clear the text selection when prompt status was enabled in immersive recall mode.
- Fixed the issue where the tool order could be lost after handwriting tool settings were synced.
- Fixed the issue where recall prompt screenshots could capture the wrong page under virtual documents.
- Fixed the issue where typing or tapping was temporarily unresponsive right after a plugin pop-up appeared.
- Fixed display anomalies with colors, cursor, and prompt labels in the chat input box under dark mode.
- Fixed the issue where Korean book titles could be truncated or displayed abnormally in the book switcher.
