PaperFlow
Read full descriptionHide full description
Write by hand and link like you type. A word you wrote becomes a link, your handwritten pages sit in the same graph as the notes you type, and one search reads both. CIRCLE A WORD. IT BECOMES A LINK. Lasso a word on the page, tap "Link to a note" and pick the note. That note lists the page under "Mentioned in". A link like [[Calculus II - notebook#page=12]] opens your handwriting on page 12. HANDWRITTEN AND TYPED, ONE GRAPH Every notebook you write is a node beside the notes you type, with links and backlinks both ways. Tap a node to see what it connects to. TYPE A WORD. FIND THE PAGE YOU WROTE. One search covers your handwriting, the notes you type and the text inside your PDFs. Your handwriting is read on your device, and it stays handwriting: it turns into text only when you ask. THE SYNTAX YOU ALREADY TYPE Wikilinks with autocomplete, note embeds, callouts, YAML properties, a templates folder, a daily note, LaTeX, Mermaid flowcharts and code blocks. Tabs, split panes, floating windows, a command palette and a quick switcher. PLAIN FILES, ON YOUR DEVICE Your notes are files: .md for what you type, .ink for what you write. The vault shows up in the Files app, every notebook exports to PDF or PNG, and the whole vault exports as a zip. Everything works offline, and two devices writing on the same page don't erase each other. A PEN WORTH WRITING WITH Press and the line thickens; tilt the pencil and it shades. Squeeze or double-tap Apple Pencil to switch tools, hover shows where the tip will land, and Pencil Pro's barrel roll turns the nib. Your palm leaves no mark. A different paper on every page. PDFS AND GOODNOTES NOTEBOOKS COME IN Import a PDF and write on top of it. Goodnotes notebooks open as PaperFlow notebooks. WHAT'S FREE, WHAT'S PLUS The notebook is free forever, with no page limit: writing, linking, search, the graph, import and export. That list doesn't shrink. PaperFlow Plus adds sync across your devices with a copy in the cloud, AI that suggests links up to a monthly allowance, and MCP access so your own AI assistant can read and write the vault once you allow it. 7 days free for new subscribers. PAPERFLOW PLUS Monthly or annual subscription with a free trial, renewed automatically until you cancel in your device Settings. The price is shown in the app before you confirm.

Notes Index

Notes Index turns your handwritten notes into a library you can search. Scan a notebook page or loose sheet with the built-in document scanner, or bring in a photo you already took. Notes Index cleans up the page, recognizes your handwriting on the device, and files it by date. FIND ANY PAGE Search for a word you wrote and Notes Index highlights exactly where it appears on the page. BROWSE LIKE PAPER Pinch through your library from a full-width page down to a dense grid. On iPad, open two pages side by side, like an open notebook. MARK IT UP Write on your pages with Apple Pencil or your finger, and recrop a page any time. PRIVATE BY DESIGN No account and no ads. Text recognition happens on your device. Turn on iCloud sync to keep your library on all your devices, stored in your own iCloud account. Export your images and text whenever you like.

Verdict
The clearest difference is in-app purchases: Notes Index at none against PaperFlow's 3. PaperFlow's advantage is update cadence (every 3 days vs every 9 days) and iOS requirement (15.0 vs 26.0). On price, ads and device support there is nothing between them.
