Stop Pushing Broken Markdown: Use a Preview Tool First
A Markdown preview tool catches formatting mistakes before you publish. No more broken headings, misaligned tables, or code blocks that don't render.
You write a README, push to GitHub, and the formatting is wrong. Headings aren't headings. The code block is missing its language tag. The table is a mess. You edit, push again, wait for it to render, and hope it's fixed this time.
This is why a Markdown preview tool saves so much time. Write on the left, see the rendered output on the right, and catch mistakes instantly.
Common Markdown mistakes that preview catches
Headings need a space after the #. ##Heading won't render as a heading, but ## Heading will. The preview shows this immediately.
Tables are the worst. The separator row needs exactly the right number of pipes and dashes. One missing pipe and the whole table breaks. The preview shows your table as it'll actually render, so you can fix alignment before anyone sees it.
Code blocks need a blank line before them in some Markdown flavors. If your code is squished into the previous paragraph, the preview catches it.
Our Markdown editor and preview supports GitHub-flavored Markdown — the same flavor GitHub, GitLab, and most static site generators use. It includes syntax highlighting for code blocks, checkboxes for task lists, and strikethrough for edits.
