ChatGPT Canvas

Canvas is ChatGPT's answer to a problem you've probably hit before: you ask the AI to change one sentence in your text, and it rewrites the whole document. With Canvas you don't have to deal with that.

Instead of getting everything as a chat reply, Canvas opens an editing panel next to the conversation. You highlight the sentence or block of code you want to change, describe what should be different, and the AI updates only that part. The rest stays as it is. It sounds simple, but it changes how you work with AI. You can also edit and format the text yourself directly. You can do that in Gemini Canvas and Copilot Pages too (which is essentially the same thing as Canvas). In Claude, you can't edit the text yourself.
