Choose an experience
Use Content Understanding Studio when you need the complete prebuilt analyzer catalog, custom analyzer authoring and building, in-context learning with data labeling, or the 2025-11-01 GA API. If you primarily work in Microsoft Foundry, use the Content Understanding playground for supported analyzers and switch to Studio when you need these Studio-only capabilities.
The analyzer gallery in each experience shows which analyzers are available for the selected API version. For analyzer descriptions, see Prebuilt analyzers.
