Butterfly is an open-source, cross-platform note-taking app built around an endless workspace for placing notes, sketches, diagrams, images and documents. It supports handwriting, typed text and Markdown, shapes and lines, and imports of PDFs, SVGs and image files. Content can be exported as PDF, SVG, images or portable Butterfly files. Files can be stored locally, and the app works offline.
The Obsidian Forum is a place for Obsidian users to discuss Obsidian and knowledge management. Its categories cover help, bug reports, feature requests, knowledge management, and sharing plugins, themes and CSS snippets, along with developer sections for plugins, API and theme design.
