Language filter

The language filter lives in the Group Localization section of the mini app. The bot detects the language of every text message and deletes those that don't fit your list.

Allow or deny

Add the languages to the list and choose the mode:

• Allow: only messages in these languages stay; everything else is deleted.
• Deny: messages in these languages are deleted; everything else stays.

The notice tells the member which language their message was detected as and which languages are allowed or forbidden.

Detection confidence

The Detection confidence slider says how sure the bot must be that a message is in a language you don't allow before it deletes it. Lower values delete on any suspicion; higher values delete only clearly foreign text and let mixed or borderline messages through. The default suits most groups; lower it only if foreign messages slip through.

Not checked at all:

• very short messages (up to 5 characters, like "ok" or "+1");
• messages from group administrators.

Languages by topic

In a forum group, a topic can have its own language list. Open Languages by topic, add the topic by its link or ID and set its list. A topic with its own list ignores the group-wide one; topics without a list, and the rest of the group, follow the group-wide list.

This is how one group can have an English topic, a Spanish topic and a general topic where both are welcome.
