Prerequisites

  • Active Intercom account with Admin access
  • Fin AI enabled on your workspace
  • Basic understanding of customer support workflows
  • Knowledge of target languages for support

Step-by-Step Instructions

1

Enable multilingual settings in Fin configuration

Navigate to Settings → Fin → Language Settings. Click Enable multilingual support and select your target languages from the dropdown menu. Set your primary language as the default fallback option. Save the configuration to activate multilingual capabilities.
Start with 2-3 languages initially to ensure quality before expanding to more languages.
2

Configure automatic language detection

In the Fin settings, go to Detection & Routing section. Enable Automatic Language Detection and set the confidence threshold to at least 85%. Configure Browser Language Fallback to use the customer's browser language when detection fails. Test the detection by sending messages in different languages.
Monitor detection accuracy in the first week and adjust the confidence threshold if needed.
3

Train Fin with multilingual content

Access Fin → Knowledge Base and upload translated versions of your help articles. Use the language tag to categorize content by language. Add multilingual conversation examples in Training Data section. Include common phrases, technical terms, and cultural context for each language.
Use native speakers to review and validate translated training content for accuracy.
4

Set up language-specific response templates

Go to Fin → Response Templates and create templates for each supported language. Use the format [LANG]_template_name for easy identification. Include greeting messages, escalation phrases, and common responses in native languages. Set appropriate tone and formality levels for each culture.
Consider cultural differences in communication styles when crafting responses for different languages.
5

Configure team routing by language

Navigate to Inbox → Assignment Rules and create language-based routing rules. Set conditions like conversation.language == 'es' to route Spanish conversations to Spanish-speaking agents. Configure Fin Handoff Rules to escalate to appropriate language teams when AI confidence is low.
Ensure each language team has clear coverage hours and backup agents assigned.
6

Implement multilingual resolution bot flows

Access Resolution Bot → Workflows and duplicate existing flows for each language. Translate all user-facing text, buttons, and path options. Use Language Branching logic to direct users to appropriate language-specific flows. Test each flow thoroughly in the target language.
Keep flow structures similar across languages but adapt content to local preferences and regulations.
7

Monitor and optimize performance metrics

Set up language-specific dashboards in Reports → Custom Reports. Track metrics like resolution rate, response time, and customer satisfaction by language. Monitor Fin's accuracy using the AI Performance dashboard. Create alerts for languages showing declining performance metrics.
Review multilingual performance weekly and adjust training data based on common failure patterns.

Common Issues & Troubleshooting

Fin responds in wrong language despite correct detection

Check if sufficient training data exists for that language in Fin → Training Data. Add more language-specific examples and retrain the model. Verify language tags are correctly applied to knowledge base articles.

Language detection accuracy is poor for certain languages

Increase the training dataset for problematic languages and lower the confidence threshold temporarily. Enable Manual Language Override option in settings to allow customers to select their preferred language manually.

Customers receive mixed-language responses

Review Knowledge Base content to ensure articles are properly tagged by language. Check for English fallback content bleeding into other language responses. Update language-specific templates to avoid cross-language content mixing.

High escalation rates for non-English conversations

Analyze conversation logs to identify common failure patterns. Expand training data for specific topics in target languages. Consider implementing language-specific confidence thresholds in Fin → Advanced Settings.
