What is Unbabel AI?
Unbabel is an AI translation platform purpose-built for customer service operations — enabling companies to support customers in any language from a single team of agents who speak only one language. Rather than building multilingual agent teams, Unbabel translates customer messages to agent language and agent responses back to customer language in real time.
Real-time translation of customer service conversations is the primary use case — a Spanish-speaking customer messages in Spanish, Unbabel translates to English for the agent, the agent responds in English, and Unbabel translates back to Spanish for the customer. The round-trip translation happens in seconds, enabling natural conversation pace.
Human quality review adds linguists for quality assurance on translated content — particularly for regulated industries, high-value customers, or complex issues where translation errors have significant consequences. For routine low-complexity inquiries, automated translation without human review provides sufficient quality at higher speed.
The AI quality estimation model predicts the quality of each MT output — routing high-confidence translations directly without human review and flagging uncertain translations for linguist review. This intelligent routing balances speed and quality based on predicted MT performance.
Integration with Zendesk, Salesforce Service Cloud, Freshdesk, and other customer service platforms enables translation within existing support workflows without requiring agents to switch tools.
With customers including Uber, Microsoft, and PwC, Unbabel validates for high-volume enterprise customer service operations.
How Unbabel AI works
Unbabel AI runs as document analysis llm software built around text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web and api.
