Markdown extensions
StackEdit extends the standard Markdown syntax by adding extra Markdown extensions, providing you with some nice features.
ProTip: You can disable any Markdown extension in the File properties dialog.
SmartyPants
SmartyPants converts ASCII punctuation characters into "smart" typographic punctuation HTML entities. For example:
| ASCII | HTML | |
|---|---|---|
| Single backticks | 'Isn't this fun?' |
'Isn't this fun?' |
| Quotes | "Isn't this fun?" |
"Isn't this fun?" |
| Dashes | -- is en-dash, --- is em-dash |
-- is en-dash, --- is em-dash |
KaTeX
You can render LaTeX mathematical expressions using KaTeX:
The Gamma function satisfying \(\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N\) is via the Euler integral
\[
\Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt\,.
\]

UML diagrams
You can render UML diagrams using Mermaid. For example, this will produce a sequence diagram:
sequenceDiagram
Alice ->> Bob: Hello Bob, how are you?
Bob-->>John: How about you John?
Bob--x Alice: I am good thanks!
Bob-x John: I am good thanks!
Note right of John: Bob thinks a long<br/>long time, so long<br/>that the text does<br/>not fit on a row.
Bob-->Alice: Checking with John...
Alice->John: Yes... John, how are you?
And this will produce a flow chart:
graph LR
A[Square Rect] -- Link text --> B((Circle))
A --> C(Round Rect)
B --> D{Rhombus}
C --> D
