Butterfly is an open-source app for people who think better with space around their ideas. Instead of writing everything from top to bottom on a fixed page, you get an endless workspace where you can place notes, sketches, diagrams, images, and documents wherever they make sense.
Use it for class notes, meeting notes, research, math, worksheets, planning, whiteboarding, storyboards, product sketches, or any project that starts messy and needs room to grow. Write by hand with a stylus, touch, or mouse, type text and Markdown, add shapes and lines, place images and photos, import PDFs, SVGs, and image files, then export your work as PDF, SVG, images, or portable Butterfly files.
Butterfly tries to stay out of your way while you work. Recent files, quick-start templates, search, folders, imports, page navigation, and tool settings are close when you need them, but the document stays at the center. You can begin with a plain page, ruled paper, a grid, dotted paper, music paper, or your own template.
As your document grows, Butterfly gives you ways to keep it understandable. Split work into pages and page folders, use layers, mark important places with areas and waypoints, save reusable parts in packs, and keep palettes and text styles ready for the next document. Almost everything you add remains editable, so you can move, resize, recolor, reorder, and refine your work later instead of starting over.
Your files stay under your control. 您的文件由您掌控。離線工作、在裝置上儲存文件、選擇不同的資料目錄，或者如果您想要自己的同步設置，請連接 WebDAV 和 Nextcloud。不需要帳戶，不需要訂閱，也不需要專有雲端。 There is no required account, no required subscription, and no required proprietary cloud.
Butterfly 是免費的，經過社區翻譯，可在手機、平板電腦、桌上型電腦和網路上使用，並根據 AGPL-3.0 許可證公開開發。
