const browserTool = true
A Markdown preview renders Markdown text into formatted HTML-like output in the browser.
Use it to check README sections, docs, notes, and drafts before publishing.
Use common Markdown
Headings, paragraphs, lists, links, quotes, bold, italic, inline code, and fenced code blocks work best.
Check platform differences
GitHub, docs systems, CMS tools, and chat apps may support different Markdown extensions.
Example
Paste a README section and check headings, bullet lists, quotes, links, and code blocks before publishing.
Assumption
The preview focuses on common Markdown syntax, not every dialect extension.
Limitation
Advanced extensions such as tables, footnotes, math, and task lists are outside this lightweight preview.
Assuming every Markdown dialect matches
GitHub, CMS editors, docs sites, and chat tools support different extensions. Check the target platform before publishing.
Pasting raw HTML expecting execution
Raw HTML is escaped here for safer previews. Use an HTML-specific tool when the job is validating actual markup.
Forgetting unsupported extensions
Tables, footnotes, math, task lists, and custom blocks may render differently or not at all in this lightweight preview.
README drafts
Preview headings, lists, links, and code blocks before committing docs.
Release notes
Check changelog formatting before sharing notes with users or teammates.
Content outlines
Preview blog outlines, documentation sections, and structured notes.
HTML snippets
Copy generated HTML when a simple Markdown-to-HTML conversion is enough.

How is preview rendering handled?
Preview rendering is designed to run in the browser based on the current public implementation.
Can I copy the HTML?
