Maho Notes vs Papyrus

Maho Notes is a markdown-based note-taking app for people who care about their words — and want to keep them. Every note is a plain .md file on your device. No proprietary format, no vendor lock-in, no servers you don't control. Sync through your own iCloud, your own GitHub repo, or keep notes purely local — your choice. A NOTES APP THAT SPEAKS YOUR LANGUAGE Full multilingual support, including search across English, 中文 (Traditional Chinese), 日本語 (Japanese), and 한국어 (Korean) — powered by a CJK-aware tokenizer that actually understands word boundaries in each language. Add furigana to Japanese kanji, Zhuyin to Mandarin, Tâi-lô to Taiwanese, or readings to Korean — all with one simple syntax: {漢字|ふりがな}. THREE WAYS TO SEARCH • Keyword search — fast SQLite FTS5 across every note • Semantic search — on-device vector embeddings find ideas, not just words • Hybrid — both, fused into one ranked list Models run entirely on-device. Nothing about your notes leaves your hardware. WRITTEN IN MARKDOWN, RENDERED BEAUTIFULLY • Full CommonMark + GitHub Flavored Markdown • KaTeX math equations • Mermaid diagrams • Syntax-highlighted code blocks • Ruby annotations for any language • Image and asset embedding • Tables, task lists, footnotes ORGANIZE YOUR WAY Vaults hold collections. Collections hold notes. Drag-and-drop reordering, custom icons and colors, hierarchical sub-collections, and per-collection ordering — all stored in plain YAML you can read. SYNC THAT RESPECTS YOU • iCloud — seamless across your Apple devices • GitHub — version your notes as a private repo, sync through your own account using GitHub's official Device Flow login (no third-party server in the middle) • Device-only — keep everything offline Conflicts get clearly-named files (note.conflict-DeviceName.md), never silent overwrites. UNIVERSAL APP One purchase covers iPhone, iPad, and Mac. Optimized layouts for each: a focus-friendly stack on iPhone, a three-column workspace on iPad and Mac, with the same vault wherever you are.

Papyrus is a native research workspace for reading, annotating, organizing, and citing PDFs — built for iPad, iPhone, and Mac. READ AND ANNOTATE Open a paper in a fast built-in reader. Highlight, underline, and mark up pages, and every highlight stays searchable and linked back to its source. Bookmark a page as you go, and pick the paper up later from a Reading card that remembers where you stopped. On iPad, a References tab looks up the open paper's reference list and related work, so you can follow a citation trail and add what matters to your library without leaving the page. WRITE ON THE PAGE WITH APPLE PENCIL Mark up a PDF directly on iPad — annotate a proof, sketch beside a figure, work a derivation out in the margin. Your ink belongs to the paper and travels with it, encrypted, to your other devices. NOTES BESIDE THE SOURCE Keep Markdown notes next to each paper: headings, tables, code blocks, LaTeX math, and [[note]] cross-references. Notes stay with the paper and export as PDF when you need to share them. NOTEBOOKS Gather notes from across your library onto themed shelves — a topic, a chapter you're drafting, a reading group. Filing a note copies nothing and moves nothing: it still belongs to its paper, still says which paper that is, and one tap takes you there and back. A note can sit on several shelves at once. Fill a new shelf from what you've already written, search it by a note's text or by the paper behind it, order it four ways — including oldest paper first, which reads your own notes forward through the literature — and export a whole shelf as one Markdown document. All Notes lists everything you've written in one place, filed or not. ORGANIZE THE WAY YOU THINK Folders — a paper can live in several — plus tags, star ratings, and seven colored flags you can name yourself, each with its own shape so they stay tellable apart at a glance. Smart Collections keep themselves current from rules you set, including flag rules. Review Duplicates finds look-alike papers and merges each set after you confirm, combining tags, folders, projects, notes, and highlights. FIND ANYTHING Search titles, authors, notes, and highlights — or the full text inside your PDFs. TURN READING INTO WRITING Projects are where a reading pile becomes a manuscript. Group the papers behind a chapter or article, give each one a role, and capture evidence — claims, quotes, and your own interpretation — tied back to the source paper and page. Write the project note from a template (related work, method comparison, experiment plan, thesis chapter, reviewer response), keep its revision history, and run a preflight that catches missing citation keys and metadata gaps before you export. Export a bundle with Markdown, a BibTeX bibliography, and the PDFs. IMPORT AND CITE Bring in PDFs, whole folders, or BibTeX and RIS files — including libraries exported from Mendeley and Zotero. Papyrus looks up metadata by DOI or arXiv ID and fills in the details. Save papers straight from Safari with the included extension. Copy citations in the style you write in, and export BibTeX or RIS whenever you need them. READ ANYWHERE Paste an arXiv link, a DOI, or a PDF URL and Papyrus imports it, looks up the details, and fetches the PDF. Add a paper to Read Later and its PDF downloads ahead of time, so a flight or a commute doesn't need a signal. Ask Siri, or search from the Home Screen, to pick up the paper you were last reading on the page you left it. YOUR LIBRARY, YOUR DEVICES Your library syncs over iCloud across iPad, iPhone, and Mac. No account to create, no tracking, no ads. Free to download and use — every feature included, no in-app purchases, no subscription.
