Use Markdown Preview when...
Use Markdown Preview when you're writing formatted content (READMEs, docs, blog posts) and need to see how the Markdown will render — for example, testing that your table syntax is correct or that code blocks display properly.
Use Word & Character Counter when...
Use Word Counter when you need to track text length and readability — for example, checking if your blog post meets the 1,500-word minimum for SEO, or counting characters for a Twitter/X bio.
Use both together when...
Content writers often use both: write a blog post in Markdown Preview for formatting, then paste the raw text into Word Counter to check word count, reading time, and sentence structure before publishing.
