Requirements and current limits
Advanced preview and visual editing require Microsoft Edge WebView2 Runtime already installed. Markdo does not download or install it. Native preview does not render images, math, Mermaid or footnotes. The advanced renderer bundles its libraries and fonts and does not automatically download Internet images.
Visual editing can normalize Markdown syntax. Enter math and Mermaid in source mode. Scroll synchronization uses the pane ratio, not exact source-line mapping. YAML metadata is displayed without full YAML validation.
DOCX does not embed images, math or diagrams. PDF uses the print dialog rather than a separate direct PDF exporter. HTML image embedding supports eligible local Markdown paths up to 10 MB per image.
Regex uses ECMAScript syntax; regex Replace All is limited to 4 MB documents. Vim/Emacs support is a basic command set. The current file-open limit is 256 MB; above 10 MB, native preview renders a region around the editing position while the editor retains the document in memory.
Version 1.0 is Windows x64 only. It does not include Linux/macOS interfaces, cloud sync or online collaboration. Choose Markdo in Windows Default Apps to open Markdown files by double-clicking them.
