Supported Languages
ChatbotIQ bots can respond in any of the following languages. Set the response language in your bot settings.
Note: With a fixed language, the bot responds in the selected language regardless of what language the user types in. If you want the bot to mirror the visitor, use Auto-detect (the default for new bots). For dedicated single-language bots, create separate bots with different language settings.

Auto-detect (auto)
Section titled “Auto-detect (auto)”When language is set to auto, the bot detects the language of each incoming user message and replies in that same language. If the language is unclear, it falls back to English. This is the default for newly created bots, so a single bot can serve a multilingual audience without spinning up one bot per language.
- Content language vs. response language: Your knowledge base content can be in any language. The bot will try to answer in the configured response language, drawing from content in whatever language is available.
- Best results come when the knowledge base content and the response language match.
- The AI model matters: More capable models (GPT-5.2, Claude Sonnet 4.6) tend to produce better multilingual output than lighter models.
