What MDedit is

MDedit is a Markdown editor for writing and previewing documents, available as a desktop app and in a browser. Its tabbed workspace gives each open document its own editing state, with synchronized Edit, Split, and Preview modes. Markdown support includes GitHub-flavored Markdown, task lists, tables, footnotes, callouts, and syntax highlighting; it also handles Mermaid diagrams and KaTeX math. Per-document find and replace includes match-case, whole-word, and regular-expression options, alongside formatting shortcuts and automatic list continuation.

The desktop app handles local files and can import images and attachments. Each imported attachment is limited to 20 MiB. Documents stay local, according to the project, which says MDedit uses no account, telemetry, document upload, or server-side rendering. Local recovery snapshots can restore open tabs, their order, the active document, content, and workspace state after an unexpected shutdown. Exports are available in HTML, PNG, PDF, CSV, and SVG. The browser version cannot resolve Markdown files on disk. MDedit is free and MIT-licensed; its project welcomes issues and pull requests through GitHub.

Who it suits
