Frequently Asked Questions
What does the Markdown preview tool do?
Markdown Preview shows live rendered HTML in one pane while you type Markdown in the other. It supports headings, lists, tables, code blocks, task lists, footnotes, and other common GitHub Flavored Markdown (GFM) features — perfect for drafting READMEs, blog posts, and technical docs.
Which GFM extensions are supported?
Tables (`|`, `---`), strikethrough (`~~text~~`), task lists (`- [ ]`), fenced code blocks with language highlighting, autolinks, footnotes, and raw HTML passthrough. Math (KaTeX) and Mermaid diagrams are typically not bundled — ask the developer if you want to extend them.
Will my Markdown render the same on GitHub or Notion?
Core syntax is universal, but platforms differ on extensions (embedded HTML, footnotes, even emoji shortcodes). DevToolkit renders GFM-first. After pasting to your destination, preview there once more and tweak if needed.
Why is my code block not highlighted?
Use fenced syntax and specify a language, e.g., ` ```js `. Stick to common aliases (`js`, `ts`, `py`, `bash`, `sql`). If highlighting still fails, that language may not be included in the highlighter's default bundle.
Is my document uploaded anywhere?
No. Both the source and the rendered output stay in your browser, so internal RFCs or meeting notes are safe to paste.
How does this compare to Typora or Obsidian?
DevToolkit is best for quick, on-the-fly previews with zero install on any device. Desktop apps shine for long-term note management with local storage and plugins. The two complement each other — web for ad-hoc work, desktop for daily knowledge bases.
