As of this date, Discord does not have a built-in official feature to quote what others have said.. but do not lose hope as there are some things you can do that are pretty much the same thing as quoting what a person has said in chat.
The first way to quote a message in Discord, is to use one line code blocks. This chat markup feature is usually used to highlight code so that it can be more-easily read, but it also works really well as a replacement for a quote feature. It's also very easy to write, so it works especially well if all you want to highlight a specific part of what someone else has said to reply to.
Putting '`' at the beginning and end of a piece of text in Discord will make it a one-line code block. For example, if you were to write `quoted message`, it would show up like:
The second and fancier way to quote a message in Discord, or at least replicate a quoted message in Discord, is to use multi-line code blocks.
With the multi-line code blocks syntax, you can make a message look like this:
This is the chat markup used to format that message:
```DiscordHelp - Today at 6:47 PM
"Quoting? Discord ain't got time for dat"```
If you're a server admin, a bot may be the most-convenient way to quote what others have said. Of course, you have to add the bot to every channel in which you wish to quote someone, so in many cases the above alternatives may be more convenient.
There are many bots available that provide message quoting functions, here are a few that we have found:
