Our own blog & newsletter is powered by it.

Writing posts

You can easily write posts in GitHub Markdown.

... and preview them with ease. You can even share a private link for feedback.

Basic formatting

Full markdown support with GitHub flavours. See GitHub Markdown Documentation for a complete guide.

Code highlighting

Using Shiki, we support syntax highlighting for most languages out of the box - online and over email. Combined with offering easy clipboard copying for online readers.

def add(a: int, b: int) -> int:
      return a + b

• Just wrap code in three backticks, e.g ```python [CODE] ```

We support admonitions too.
