AI writing assistant

Canvas is a new interface launched by OpenAI designed to improve writing and coding projects through collaboration with ChatGPT. It allows users to work with ChatGPT in a separate window, going beyond a simple chat interface. Canvas leverages the GPT-4o model to better understand the user's context and provide inline feedback and suggestions. It supports direct editing of text or code, and provides a quick operation menu to help users adjust writing length, debug code, etc. Canvas also supports version backtracking to help users manage different versions of the project.
