Pencil brings handwriting, sketching, PDF annotation and watercolor painting to iPad and iPhone. Designed especially for Apple Pencil on iPad, it also works with other compatible styluses and your finger. Take notes in class, mark up a document, plan your week or paint an idea while it is still fresh. • Write and sketch your way. Use Apple Pencil on iPad, or write and draw with a compatible stylus or your finger on iPad and iPhone. Start a PDF note from a paper template, choose your ink colors and add typed text, images and shapes. Use lined or grid backgrounds to give your notes structure. • Make your PDFs useful. Highlight passages, add comments, write in the margins and insert your signature. Search inside a document, bookmark important pages and rearrange, duplicate or rotate pages as your work develops. • Keep the conversation with your notes. Record audio directly in a PDF note and play it back alongside the page. Revisit a lecture, meeting or explanation without separating the recording from your written notes. • Type when words come first. Create formatted Text Notes with fonts, colors, lists, checklists, tables and images. Turn a quick thought into a clear set of notes, a plan or a longer draft, then export it as a PDF to share. • Explore watercolor painting. Open a dedicated painting workspace, choose your paper and experiment with brushes, mixed colors and washes. Paint from a reference photo, try guided practice lessons and export your painting as an image or PDF. • Bring paper into your notebook. Scan documents with the camera, import files through the Files app and add photos to your work. Keep notes, PDFs and paintings organized in folders, ready to return to when you need them. • Get help from AI. Ask questions about your documents, summarize a passage, explain an unfamiliar concept or translate selected text. Use AI Chat to work through an idea alongside your notes.

About

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.
