Azure AI Translator

What it does

Azure Translator in Foundry Tools takes in text, documents, and images and returns translated output in more than 100 languages. It can translate in real time or in batches, detect the source language, offer bilingual dictionary lookups and script conversion, and use custom models trained on your own translated material to handle domain-specific terminology. Developers call it through a REST API from their applications, websites, or agentic workflows.

Teams typically embed it into products such as multilingual chatbots, call-center translation, in-app messaging, or content localization pipelines. Its distinguishing points are the production translation engine that the page says powers Word, Outlook, Teams, and Edge, and the option to combine neural machine translation with large language models for tone, gender, and style control. Translator is listed as one tool within the broader Foundry platform, alongside services such as Azure Speech and Azure Language.

It suits developers and enterprises that need to add translation to software or agents and can work with a REST API and an Azure account. Access is through the Azure portal and API, with a free tier of 2 million characters per month for standard and custom translation combined. Pricing is consumption-based and billed by characters, so costs scale with volume. Custom models incur separate hosting, training, and translation charges, and the cost of translating document images is billed per thousand images.

What it can do

• Real-time and batch text translation across more than 100 languages
• Document translation for supported file formats
• Automatic source language detection
• Bilingual dictionary lookup and transliteration
• Custom translation models trained on domain-specific translated data
• Optional use of large language models such as GPT-4o for tone, gender, and style customization

Works with

• Azure Speech
• Azure Language
• Azure Content Understanding
• Azure Document Intelligence
• Azure Vision
• Foundry Tools agent platform

Example workflows

Multilingual support chat

Input: a customer message in an unfamiliar language. Steps: detect the source language, translate the message to the agent's language, and translate the agent's reply back. Output: translated messages in both directions within the support tool.

Batch document localization

Input: a set of product manuals in supported document formats. Steps: submit the documents for document translation to a target language, optionally using a custom model for domain terms. Output: translated documents returned for review.

Before you choose

• Pricing is per character translated; high-volume or custom-model use can cost substantially more than the free allowance, so estimate usage with the pricing calculator.
• Custom translation adds separate charges for model hosting, training, and translation, and hosted models are billed as a flat monthly fee even if used for part of the month.
• Standard and custom translation discounts apply to different commitment tiers, so mixed workloads may need two separate instances to get both discounts.

2. Create a Translator resource in the Azure portal and note its key and endpoint.
3. Use the documentation quickstarts to send a first text translation request through the REST API.

F0 free tier includes 2 million characters per month across standard and custom translation. S1 pay-as-you-go is billed per million characters, with per-thousand-image charges for image documents and reduced rates on commitment tiers. Custom translation adds hosting, training, and translation charges. Exact numeric rates are masked in the reviewed information and should be confirmed on the pricing page.
