What markdown rules does the linter check for?

The markdown linter checks for common issues including heading hierarchy violations, trailing whitespace, empty links, inconsistent list markers, missing alt text for images, and improper code block formatting.

Does the markdown linter fix issues automatically?

No, the linter identifies and reports issues with line numbers and rule names but does not modify your markdown. This gives you full control over which changes to make.

What heading hierarchy violations does it detect?

The linter detects skipped heading levels (e.g., jumping from h1 to h3), multiple h1 headings in a single document, and inconsistent heading styles that can harm document structure and accessibility.

Can I lint large markdown documents?

Yes, the markdown linter processes documents of any size efficiently since all analysis happens locally in your browser. Very large files may take slightly longer to analyze.

Is my markdown content private when using this linter?

Yes, all linting happens entirely in your browser. No markdown content is sent to any server, ensuring complete privacy for sensitive documentation and content.
