What is Azure AI Language?

Azure AI Language is Microsoft's cloud based natural language processing service, part of Azure AI Foundry tools. It provides prebuilt capabilities including sentiment analysis, key phrase extraction, language detection, named entity recognition, PII detection and redaction, text summarization, and question answering, alongside customizable options like conversational language understanding, custom text classification, and custom named entity recognition built through Language Studio without requiring machine learning expertise.

Pricing is usage based and billed per text record, a unit equal to 1,000 characters of input. Sentiment analysis, key phrase extraction, language detection, summarization, question answering, NER, and conversational language understanding all share 5,000 free text records per month. Paid usage runs on tiered per-record rates with volume discounts, plus commitment tiers for high-volume customers, and containers are available for on-premises or disconnected deployment.
