Top 100 use cases
What people and companies actually use AI for, ranked by measured usage. Switch between everyday use on Claude.ai and products built on the API, and between work and all usage. Each use case shows the capability it relies on and the models that enable it.
About the data. Usage shares come from the Anthropic Economic Index (CC-BY 4.0), which classifies millions of real conversations. It measures usage of Claude, so it shows what AI is used for, not how each model is adopted. Time estimates are Anthropic’s, per conversation.
How models are matched. Each use case’s capability comes from its main output type in the Index. The chips show the directory models rated highest for that kind of work on LMArena (CC-BY 4.0). Release 2026-06-26 · dataset · retrieved Sep 19, 2026.
