Format your messages
Zulip uses a variant of
GitHub Flavored Markdown
to allow you to easily format your messages.
**bold**, *italic*, and ~~strikethrough~~ text
***~~All three at once~~***
* bulleted lists
* with sub-bullets too
* sub-bullets start with 2 spaces
* start sub-sub-bullets with 4 spaces
- dashes and
+ pluses are ok too
1. numbered lists
1. increment automatically
1. one more
Zulip auto-linkifies URLs and valid stream names. You can also add a
custom linkifier to link
#1234 to your ticketing system.
Auto-detected URL: zulip.com
Named link: [Zulip homepage](zulip.com)
Stream: #**stream name**
Topic: #**stream name>topic name**
Custom linkifier: #1234 (links to ticket 1234 in your ticketing system)

You can also use
~~~ to start codeblocks, or just indent the code 4 or more spaces.
Zulip supports syntax highlighting for hundreds of languages, and a
typeahead will pop up when you start typing after the
```. If you can't
find your language, search for it here
and try the short names listed for the lexers for your language.
Organization administrators can also configure a default syntax
highlighting language. In this configuration, one can use
to display content without any syntax highlighting.
\int_a^b f(t)\, dt = F(b) - F(a)
Zulip's LaTeX rendering is powered by KaTeX.

You can use spoilers to hide content that you do not want to be visible until
the user interacts with it.
Normal content in message
```spoiler Spoiler Header
Spoiler content. These lines won't be visible until the user expands the spoiler.
The spoiler will initially display in a collapsed form:
Clicking the arrow will expand the spoiler content:
Emoji and emoticons
To translate emoticons into emoji, you'll need to
enable emoticon translations.
You can also add custom emoji.

Learn more about mentions here.
Users: @**Polonius** or @**aaron|26** or @**|26** (two asterisks)
User group: @*support team* (one asterisk)
Silent mention: @_**Polonius** or @_**|26** (@_ instead of @)
The variants with numbers use user IDs, and are intended for
disambiguation (if multiple users have the same name) and bots (for
the variant that only contains the user ID).
Mention a time
When collaborating with people in another timezone, you often need to
express a specific time clearly. Rather than typing out your timezone
and having everyone translate the time in their heads, in Zulip, you
can mention a time, and it'll be displayed to each user in their own
timezone (just like the timestamps on Zulip messages).
A date picker will appear once you type
Our next meeting is scheduled for <time:2020-05-28T13:30:00+05:30>
A person in San Francisco will see:
Our next meeting is scheduled for Thu, May 28 2020, 1:00 AM.
While someone in India will see:
Our next meeting is scheduled for Thu, May 28 2020, 1:30 PM.
You can also use other formats such as UNIX timestamps or human readable
dates, for example,
<time:May 28 2020, 1:30 PM IST>.
The initial pipes (
|) are optional if every entry in the first column is non-empty.
The header separators (
---) must be at least three dashes long.
|| yes | no | maybe
| A | left-aligned | centered | right-aligned
| B | extra spaces | are | ok
| C | **bold** *italic* ~~strikethrough~~ :smile: ||
Paragraphs and lines
One blank space for a new paragraph
New line, same paragraph
---, ***, or ___ for a horizontal line
