The Markdown Standard

Markdown is a lightweight markup language that you can use to add formatting elements to plaintext text documents. Created in 2004, it is now one of the world's most popular markup languages for documentation (GitHub, StackOverflow, Obsidian).


Developer Workflows: Engineers use Markdown to ensure documentation is portable and version-controlled. By separating content from presentation, Markdown allows for clean, distraction-free writing that can be rendered into beautiful HTML or PDFs instantly.

Frequently Asked Questions

Is there a character or word limit for the text tools?

There is no strict limit — processing is done in your browser's memory. For very large documents (100,000+ words), performance depends on your device's available RAM.

Does the word counter count words differently from Word or Google Docs?

Word counting algorithms differ slightly between tools. Our counter follows standard tokenization rules: whitespace-separated sequences of characters. Results are consistent with most professional editors.

Can I use the text tools on mobile devices?

Yes. All text tools are fully responsive and work on smartphones and tablets. The interface adapts to smaller screens with no loss of functionality.
