Have you ever wondered if there's a way to write things that's both simple and good-looking, and can be easily posted online? The answer is Markdown! It was created in 2004 by two tech giants—John Gruber and Aaron Swartz.

John Gruber is a super famous tech blogger and programmer, and his blog Daring Fireball is well-known in the industry. His original intention for creating Markdown was very simple: he wanted a format that's easy to read, easy to write, and can be easily turned into web pages (HTML). And so, Markdown was born!

What Can Markdown Do? What Problems Does It Solve? ​

When writing in daily life, we always encounter some headaches, such as:

  • Word is too troublesome: Want to write a short article, but have to search for formatting tools among a bunch of buttons.
  • Messy formatting: Exchange a document with a friend, open it, and find all the font sizes are off.
  • Huge files: Just a few paragraphs, but the saved file is dozens of MB.
  • Device incompatibility: Files written in Word can't be opened on another device.
  • Chaos from revisions: Multiple people writing together, and no one knows who changed what.
  • Distracted by formatting: Spend half a day adjusting styles, and the writing inspiration is long gone.

Markdown is like a magic wand, solving everything with one move!

  • Super simple: A few symbols can handle headings, lists, bold text; you can learn it in five minutes.
  • Ultra-lightweight plain text: Files are as small as a feather and can be opened anywhere.
  • Focus on content: Don't worry about formatting; writing is super smooth.
  • Use on any device: Phone, computer, tablet, you can edit anywhere.
  • Super version control friendly: With tools like Git, every change is clear.
  • Formatting is always consistent: Looks the same no matter where you open it.

In the AI era, Markdown is like having "cheat codes." Why?

  1. AI loves it: Tools like ChatGPT handle Markdown input and output very smoothly.
  2. Standard for note-taking apps: Popular apps like Obsidian, Notion, and Logseq all use Markdown.
  3. Programmers lead the way: GitHub, Stack Overflow are full of Markdown.
  4. Efficiency explosion: Too much information; Markdown can quickly jot it down and organize it.
  5. Learn once, use everywhere: Blogs, notes, documentation, chat—it works anywhere!
  6. Connect knowledge: Modern note-taking tools can also use Markdown to create links, weaving a knowledge network.
  7. No vendor lock-in: Your files won't be locked into a specific software; you can move them anytime.
