Frequently Asked Questions

A Markdown linter analyzes your Markdown files for syntax errors, style inconsistencies, and formatting problems. It helps maintain readability, ensures compatibility across different Markdown renderers, and enforces team style guides automatically.

Common errors include: missing space after heading #, inconsistent list markers, unclosed code blocks, broken links or missing reference definitions, missing blank lines before/after headings or lists, and duplicate top-level headings.

It runs directly in your browser using JavaScript. No data is uploaded to any server. Your Markdown is parsed and checked against a set of customizable rules, and issues are displayed in real-time with line numbers and descriptions.

This tool focuses on detection. For automatic fixing, you can use tools like markdownlint-cli --fix or editor plugins that support quick fixes. Our report helps you locate and manually correct problems.

We enforce a subset of the popular markdownlint rules, including heading style, list spacing, code block closure, link validation, and blank line requirements. These align with the CommonMark and widely accepted best practices.
Pro tip: Integrate linting into your CI/CD pipeline with markdownlint or remark-lint to enforce consistent Markdown quality across your team.
