This is similar to Artifacts [0] in Claude.

I think you can enable Artifacts, which are similar to OpenAI Canvas. Recently, Anthropic also added the ability to select elements within the created Artifact and adjust them (e.g., adjust length, improve code), similar to what Canvas can do.

Claude can generate Artifacts but they are not inline editable and they keep getting regenerated at every prompt.

Canvas appears to be different in that it allows inline editing and also prompting on a selection. So not the same as Claude.

I'm guessing they mean Artifacts: https://www.anthropic.com/news/artifacts
