What is Markdown and do I need it for notes?

Updated October 2026 · How we answer

Short answerMarkdown is a simple plain-text style that uses symbols like hash signs and asterisks to format headings, bold text, and lists. You do not need it to take notes, but it helps if you want portable files.

How Markdown works

In Markdown, a line starting with a hash sign can become a heading, and words wrapped in asterisks can appear bold or italic. Because the formatting is plain text, the file stays readable even in apps that do not render it.

Many note apps support Markdown either fully or partly, and some use it behind the scenes. Learning a few symbols covers most everyday formatting.

  • Hash signs create headings.
  • Asterisks make text bold or italic.
  • Hyphens or numbers create lists.
  • Plain text files open in almost any editor.

Deciding whether to use it

If you want notes you can move between apps or open in a text editor, Markdown is a strong choice. If you prefer buttons and visual formatting, a standard rich-text editor may feel faster.

You can start with a few basics and add more as you need them. Most people learn the core symbols in one short session.

If you switch apps later, Markdown files usually carry over with little cleanup, which is a practical reason many people choose it. Keeping one folder of plain files as an archive gives you a copy that is separate from any single app.

Common mistakes

  • Trying to learn every Markdown feature before taking your first note.
  • Assuming all apps display Markdown the same way.
  • Mixing formatting styles in one note, which can look messy.
