NoteBlob is a free and opensource markdown note editor for ios and macos backed by git. No proprietary formats, no complex versioning ; just a clean git client built for note taking and AI integration. ## WHY ANOTHER NOTE APP? Notes can be confidential and personal, yet note editors usually rely on opaque technologies and, at some point, a payment system. Notes should be easy to edit, versioned, independent of any company, exportable, and confidential. Moreover, in the age of AI, your notes should be model-readable and ready to process. NoteBlob fixes that by relying on something other than itself: at its core, it uses Git and Markdown, the most universal, well-known technologies for editing and backing up data. NoteBlob is simply an interface that makes the experience more user-friendly and iOS-compatible. It provides no custom mechanism or technology, the source of truth remains your Markdown files and your Git repository. Tired of it? Just delete the app; your notes stay in your Git repo as plain Markdown files. ## FEATURES - Markdown editor with a powerful live preview and a fast native editor - GitHub sync a straightforward commit, push, and merge workflow - Full-text search across all your notes / folders - Plugins enhance user experience by importing JS modules. -- Mermaid -- Syntax highlighting And more
