Edit Markdown with live preview, multi-document tabs, search and replace, and local PDF export. Free and open source.

markdim is a desktop Markdown workspace for Windows that brings your source, rendered preview, and document library together. Open a .md or .markdown file, work with a folder of documents, or start with a blank note. The preview updates as you write, and you can export a PDF directly from the app.

Write and review
Edit Markdown in the source pane and view the rendered result alongside it. The preview supports CommonMark and Markdig's advanced extensions, including tables, nested lists, task lists, links, and code blocks with syntax highlighting.

Organize your documents
Use reorderable tabs, the document library, search, and the heading outline to move through your notes. Find and replace text in the active document.

Make the workspace yours
Choose a light or dark theme, resize the library, editor, and preview panes, and adjust editor text size. Optional whitespace and line-ending markers help inspect source text.

Your documents stay on your device
markdim does not require an account and includes no cloud sync, ads, or telemetry. To display remote images referenced by a document, the app may request those images from their HTTPS hosts. The document itself is not uploaded.

markdim is free and open source under the MIT License. This beta is for x64 PCs running Windows 10 version 2004 (build 19041) or later, and Windows 11. The app interface is available in English and French.

Ikonym turns a username, account ID, or other stable identifier into a deterministic geometric avatar. The same identifier and options always produce the same SVG, generated locally without sending the identifier to a server.

Try five mosaic densities

Choose 3×3, 5×5, 7×7, 9×9, or 12×12 tiles. Four geometric motif families alternate across horizontal and vertical neighbors, regardless of color, while every tile joins edge-to-edge.
Integrate it with your product

Use the npm package, the PHP Composer helper, the Python package, the Rust crate, the Go module, the Dart package, the NuGet package, or portable DiceBear JSON definitions with compatible SDKs. Ikonym is open source under the MIT License. Redistribution, including modified versions, must retain the original copyright notice and license.
