QuillStone

Handwritten sheets for Obsidian: draw with a stylus or mouse, on multi-page sheets stored as lightweight, diffable .draw files — with live previews embedded right in your notes.

Features

• Freehand drawing — pen and highlighter, with pencil-pressure sensitivity and adjustable size.
• Shapes — rectangle, ellipse, triangle, line, and arrow, drawn by dragging or auto-recognized from a held freehand stroke.
• Eraser — by stroke or by zone.
• Selection tool — move, resize, rotate, recolor, restack, duplicate, cut/copy/paste (including across sheets and pages), lock elements in place.
• Images — paste, drag-and-drop, or insert from a file picker; crop after insertion. Screen-capture a rectangular area of the page into a new image.
• PDF import — bring in a PDF as a background you can draw over, one page of the PDF per page of the sheet. Works with large, multi-hundred-page PDFs (the PDF is stored once, privately, never duplicated per page).
• PDF export — export any sheet back to a real PDF file, at print resolution.
• Multi-page sheets — add, delete, reorder, and move pages; each page has its own background, density, paper format, and orientation.
• Paper formats — A3, A4, A5, Letter, Legal, in portrait or landscape.
• Backgrounds — blank, grid, ruled lines, dots, Seyès (French ruled), music staff, isometric — each with three density levels.
• Embedded preview — ![[sheet.draw]] renders a live, paginated thumbnail directly inside your notes, expandable and clickable to open the full sheet.
• Laser pointer — a temporary, non-persisted pointer for presenting without marking up the page.
• Undo/redo, per-page color palettes with recently-used colors, light/dark theme support.

Usage

• Create a new sheet from the command palette (QuillStone: New sheet) or by right-clicking a folder/note.
• Import an existing PDF as a new sheet, or append its pages to a sheet you already have open.
• Embed a sheet in any note with ![[sheet.draw]].

File format

A sheet is saved as a .draw file: plain JSON, one entry per page, each stroke stored as a list of points rather than a rasterized image — small, readable, and diffable in Git.

Platform notes

QuillStone works fully on Obsidian desktop. On mobile, drawing, shapes, images, and PDF import/export all work; copying/pasting between sheets falls back to the browser's clipboard API, which — depending on the mobile platform's permissions — may be less reliable than on desktop.
