What is Leno AI Multi Language Support?
Leno AI Multi Language Support allows your AI agent to detect the language a visitor is writing in and respond natively in that language — without translating everything through English first.
This means your knowledge base content, product names, links, and tone are preserved as-is, and your customers receive accurate, natural responses regardless of where they are in the world.
Benefits at a glance
How it works
When a visitor sends a message, Leno AI runs the following process:
Supported languages
How to enable the feature
-
1
Go to your Leno AI Settings page from the dashboard sidebar.
-
2
Scroll down to the Leno AI Multi Language Support section — it appears between the Leno AI Activation section and the Product Catalog section.
-
3
Toggle Enable Leno AI Multi Language to ON.
Once the toggle is ON, the Default Language and Supported Languages options will appear below.
Setting a default language
What is the default language?
The default language is the language Leno AI will use automatically when it cannot detect the visitor's language. Think of it as the fallback language.
Leno AI switches to the default language when:
-
•
The visitor's language cannot be detected (e.g. very short messages, emojis only)
-
•
The detected language is not in your allowed list
How to Set the Default Language
-
1
In the Leno AI Multi Language Support section, find the Default Language dropdown.
-
2
Click the dropdown and type to search, or scroll to find your language.
-
3
Select your preferred language.
-
4
The setting saves automatically.
It simply defines what Leno AI will use if it cannot determine the visitor's preferred language.
All languages vs. specific languages
After enabling the feature, you can choose how broadly Leno AI responds:
How to select specific languages
-
1
Under Supported Languages, select Specific Languages.
-
2
A language input box appears with your default language already added as a locked chip — it cannot be removed.
-
3
Click inside the box and start typing to search for a language.
-
4
Select a language from the dropdown — it will appear as a chip inside the box.
-
5
To remove a language, click the × on its chip. Changes save automatically.
Frequently asked questions
What happens if a visitor writes in a language that is not allowed?
Leno AI will let the visitor know it does not support that language in this conversation, and will respond in your configured default language.
Is the widget language the same as the AI language?
No. These are two independent settings. Your widget language controls the chat UI (button labels, input placeholder text, etc.). The Leno AI default language controls which language the AI responds in. You can configure them separately.
What happens with very short messages like "hi" or "ok"?
These words exist in many languages, so detection may be uncertain. In those cases, Leno AI falls back to the default language. As the conversation continues and more messages are sent, the language detection improves.
Does my knowledge base need to be translated for this to work?
No. Leno AI generates answers in the visitor's language even if your knowledge base is written in a different language. No manual translation of your content is required.
What about greeting and handover messages I configured?
Template-based messages (greetings, goodbyes, handover confirmations, fallback messages) are automatically translated by Leno AI into the visitor's language when multi language is enabled.
What if translation fails?
If Leno AI cannot translate a template message, it falls back to the original message in your default language. The conversation continues without interruption.
