MarkFlowy

MarkFlowy is an open source Markdown editor for macOS, Windows and Linux that keeps files on the user's own machine. It offers both visual and source editing, works with Markdown, JSON and plain text, and is tuned so that long documents open, scroll and edit smoothly. Users can open a single file for quick writing or a whole folder as a workspace with a file browser and a document outline. A web app is also offered in beta. AI is optional. A user can connect their own AI service for conversation, summaries and translation, or run a local model through Ollama. The product also publishes an official Skill so an AI assistant can open, save and export documents in the editor. Output stays portable. Files remain plain Markdown in the user's folders, and documents can be exported as HTML or an image, or saved as a PDF through the system print dialog. Themes, shortcuts and a command palette allow the writing environment to be customized. It suits writers, note takers and developers who want a focused editor without an account or cloud storage. The project is developed in the open and invites contributions. The site does not publish pricing.
