# Setting up chat filters

Chat filters are a powerful tool to censor words, IPs or URLs:

Despite its name, chat filters do work in anvils, books and signs too.

## Filtering by literals

```yaml
    filter:
        ...
        literalFilter:
        - i hope you step on a lego
```

This will censor the phrase "i hope you step on a lego". Literal filters are case insensitive.

## Filtering by regex

Users can also filter with their own RegEx rules. Here's an example:

```yaml
    filter:
        ...
        customRegexFilter:
        - ^dog
```

This will censor every word starting with "dog".
