- Does this support GitHub Flavored Markdown?
- Yes. Common GFM features such as tables, fenced code blocks, and task lists are supported.
- Can I use this for README files?
- Yes. It is designed for README writing and preview checks before committing changes.
- Does the tool convert Markdown to HTML?
- The preview renders Markdown as HTML so you can inspect final formatting behavior.
- Is this useful for documentation teams?
- Yes. It helps technical writers and engineers verify formatting before publication.
- Can this replace my IDE Markdown preview?
- It complements rather than replaces IDE previews. VS Code's built-in Markdown preview is great for editing, but this tool is useful for: (1) sharing a Markdown draft with a teammate who doesn't have your IDE, (2) testing how content will render on GitHub specifically (uses GFM exactly), (3) pasting LLM-generated Markdown to check formatting, (4) quick ad-hoc previews without opening an IDE project.
- Does this render the same as GitHub README?
- Yes — GFM rendering matches what GitHub displays. You may notice tiny CSS differences (GitHub uses their own stylesheet), but the structure, syntax highlighting, table formatting, and task list rendering are identical. What you see here is what your GitHub README will look like.
- Can I write LaTeX math equations?
- Yes — wrap inline math in `$...$` (e.g., `$E=mc^2$`) and block math in `$$...$$`. Rendering is via KaTeX, which supports most LaTeX math notation. Useful for documentation of algorithms, scientific computing libraries, and academic content.
- Does it support Mermaid diagrams?
- Yes — fenced ```mermaid code blocks render as diagrams: flowcharts, sequence diagrams, gantt charts, class diagrams, entity-relationship diagrams. GitHub also supports Mermaid in READMEs now, so this preview matches GitHub's rendering.
- Is my markdown content private?
- Yes — completely. All parsing and rendering runs in your browser. Your Markdown content never leaves your device, never reaches a server, never gets logged. Safe for proprietary docs, draft articles, internal notes. Verify in DevTools → Network: zero outgoing requests.
- Can I export the rendered HTML?
- Yes — there's an 'Export as HTML' button that copies the rendered HTML to your clipboard. Useful when you need clean HTML output from Markdown source (e.g., for email templates, CMS imports, or pasting into rich-text editors that don't accept Markdown).
