Foundry AI agents automatically detect the language a visitor is writing in and respond natively — no configuration, no extra cost, no language packs to install.
These languages are tested and reliable in live customer-facing deployments. Native-level comprehension, natural responses, full context awareness.
Strong comprehension and natural output. Minor nuance gaps may occur in highly specialised or idiomatic content.
Our agents respond fluently in RTL languages out of the box. For the full experience — where the chat interface itself flips to right-to-left layout — a small UI configuration is required. This is available as an add-on and typically takes less than a day to implement.
Not all language capabilities are equal. Here's the honest breakdown.
| Capability | Status | Notes |
|---|---|---|
| Auto language detection | ✓ Automatic | No configuration needed. Detects from first message. |
| Text chat response | ✓ All languages | Works across all 35+ supported languages. |
| Mixed-language conversation | ✓ Supported | Agent follows the user — if they switch language mid-conversation, so does the agent. |
| RTL text rendering | ◐ Text yes, UI optional | Agent text is correct RTL. Widget UI flip requires configuration. |
| Voice (text-to-speech) | ⚙ Available | Multi-language voice via ElevenLabs. Language routing configured per deployment. |
| PDF generation in language | ✓ Supported | Branded PDF output matches the conversation language. |
| Email follow-up in language | ✓ Supported | Follow-up emails sent in the visitor's detected language. |
