**Filters**

• /filters: List all active filters saved in the chat.

**Admin only:**
• /filter "`<keyword>`" `<reply message>`: Add a filter to this chat. The bot will now reply that message whenever 'keyword'
is mentioned. If you reply to a sticker with a keyword, the bot will reply with that sticker.

If you want your keyword to be a sentence, use quotes. eg: /filter "hey there" How are you doin?
**Example:**
`/filter "filtername" Reply Text`

Aliases for filters can be too set, just put '|' between the filternames you want.
**Example:**
`/filter "filtername1|filtername2" Reply Text`
Using the you can make a single filter work on 2 filternames without manually adding another one.

• /stop `<filter keyword>`: Stop that filter.

**Note:**
For filters with aliases, if you stop one alias, the filter will stop working on other aliases too.

**For Example:**
If you stop the "filtername1" from above example, the bot will not respond to "filtername2".

**Chat creator only:**
• /removeallfilters: Remove all chat filters at once.

**Note:**
Currently there is a limit of 50 filters and 120 aliases per chat.
All filter keywords are in lowercase."""
