Auto-translate messages (Beta)¶

Available on Enterprise Advanced plans

From Mattermost v11.5, messages in channels with auto-translation enabled are automatically translated into your preferred language. This enables seamless multilingual collaboration — you can read and respond in your own language while teammates do the same in theirs.

How auto-translation works¶

Your system admin must first enable auto-translation for your Mattermost instance. Then, a system admin or channel admin can enable it for individual channels. When autotranslation is enabled in a channel:

The language of each message is automatically detected.
Messages are translated into your preferred display language and shown in place of the original text.
Code blocks, URLs, and @mentions are preserved and not translated.
Translations happen asynchronously — there may be a brief delay before the translated text appears.
Messages written in your preferred language are not translated.

View translated messages¶

Translated messages display in place of the original text. To view the original untranslated message, select the translation icon on the message.

Set your preferred language¶

Auto-translation translates messages into your Mattermost display language. To change your display language:

Select the gear icon to open Settings.
Select Display > Language.
Choose your preferred language.
Select Save.

See the language documentation for more details.

Opt out of auto-translation in a channel¶

You can opt out of auto-translation on a per-channel basis if you prefer to see original messages in a specific channel. To opt out:

Open the channel where you want to disable auto-translation.
Select the channel name at the top to open the channel menu.
Disable the auto-translation option for this channel.

You’ll see original, untranslated messages in that channel going forward. You can re-enable auto-translation at any time using the same steps.

Limitations¶

Direct and group messages: Your system admin may have restricted auto-translation in direct and group messages. If auto-translation isn’t available in a direct or group message, contact your system admin.
Short or mixed-language messages: Very short messages or messages that mix multiple languages may not be reliably detected and translated.
Code-only messages: Messages that contain only code blocks are not translated, as code is preserved in its original form.
Translation accuracy: Translation quality depends on the translation provider configured by your system admin. Some languages or specialized terminology may produce less accurate results.
