You can already manually translate your multi-language flow, but auto-translating with AI can save you a lot of time.

Auto-translate uses TextIt's built-in Large Language Model (LLM). For other AI features, you can also add your own LLM, such as OpenAI ChatGPT or Anthropic.

See our full guide on using the Call AI action in your flow and the many ways you can use AI to reach your goals.

Build your Multi-Language Flow

Before you build a flow, make sure you've already added additional languages to your workspace. Without these, only your default language will appear in the flow editor.

In the example flow below, we're translating a message from English to Spanish. After creating the Send Message node in English, we'll switch to Spanish using the language drop-down menu on the toolbar.

The menu lists all the languages you've added to your workspace, along with how much of the flow has been translated into each one. In this example, the flow is already fully translated into Chinese, and Spanish is at 0%. Click the language you want to translate into.

After you switch to Spanish, the Send Message node turns yellow and the auto-translate icon appears next to the language menu.

Click the auto-translate icon to open the Auto Translation dialog. All remaining untranslated text for the language will be translated. Check Update existing translations if you also want to replace text that has already been translated, then click Translate.

The flow is then translated right away. The language drop-down menu shows the completion percentage, so you can see whether any nodes, or categories on Wait for Response nodes, still need translating. The Make Default button lets you switch your default language to your secondary language, in this case Spanish.

Considerations

LLMs are powerful tools, but they aren't perfect. Don't send your flow to contacts without reviewing the translations.

When using SMS and translating into languages with extended characters, be mindful of message length. SMS messages are limited to 160 characters, but only if they use the standard GSM7 alphabet. If you use characters outside it (such as emojis or Chinese characters), the message is sent as Unicode, which lowers the limit to 70 characters.

If you have questions, send us a message via the support widget in the bottom right corner.
