About
Microsoft Translator offers real-time translation through a consumer app and via the Azure Translator API for developers and businesses. The app handles text and voice translation, supports multi-person multilingual conversations, and works offline for a set of downloaded language packs. The Azure API provides a permanent free tier of 2 million characters per month, with pay-as-you-go pricing beyond that, making it practical for small projects without upfront costs. Enterprise customers can access custom translation models trained on their own terminology and style.
