writing blocks and code blocks

Editable sections of writing or code that appear directly inside ChatGPT's replies.

Which capability it is

Close to, but not: A document or app it makes for you

They appear inside the chat reply, not as a standalone document beside the chat.

writing blocks and code blocks is close to a document or app it makes for you, not a match. Here’s what the other tools call a document or app it makes for you.
