FAQ
Does it support GitHub Flavored Markdown?
Common GFM features work—lists, emphasis, links, and line breaks. Advanced extensions may need a dedicated renderer.
Why might preview differ from source?
Preview applies browser styles and sanitization; some unsafe or malformed tags may be filtered in the final view.
Is Markdown uploaded?
No. Rendering and sanitization run locally in your browser.
