About this chapter
What this chapter covers
This chapter is about one service: Azure Content Understanding in Foundry Tools. It uses generative AI to turn documents, images, audio and video into structured output, either Markdown for search and reading, or JSON fields that match a schema you define.
You will learn what an analyzer is, which prebuilt analyzers exist, how to design a custom one, and how an application calls the service and reads the result.
How the topics fit together
The same idea applies to every kind of content.
- Content Understanding for documents and images covers analyzers, field schemas, confidence scores and the studio.
- Audio, video and extraction applications covers audio and video analyzers, and the Python and REST pattern for calling the service.
The analyzer is the key idea. It holds the settings, the field schema and the models, and it applies them the same way to every input.
