just the day after openai announced that it had received the largest financing of us$6.6 billion in history, it launched the first major interface update "canvas" since the launch of chatgpt two years ago.

canvas is a newly designed interactive interface designed specifically for writing and programming tasks. it is no longer limited to the traditional chat mode, but through an independent window opened next to the standard dialog box, it provides an in-depth collaboration space between users and chatgpt to jointly create and optimize projects.

it is built on the specially trained gpt-4o, where users can edit text or code directly. select any part that needs to be modified, and chatgpt will give precise optimization suggestions based on the context. the system also provides a shortcut menu including adjusting text length, changing reading level, code review fixes, additions, etc. additionally, users can easily restore a previous working version via the "back" button.

opening canvas is simple: select "gpt-4o with canvas" in the model selector, just enter a prompt like "use canvas..." or "launch canvas..." and a new window will pop up. when chatgpt detects a potentially helpful scene, the canvas is automatically opened without user invocation.

let’s take a look at its various functions in detail.

canvas assists writing

canvas can generate a first draft of a project for you based on instructions for you to edit with ai, or it can also optimize existing drafts. suitable for writing long articles, reports, plans, emails, etc.

built-in 5 practical shortcut functions for writing:

suggested editors: chatgpt provides insider suggestions and feedback.

adjust length: expand or shorten the length of the document.

change reading level: adjust reading levels from kindergarten, middle school, college to graduate school.

final touches: a thorough review of grammar, clarity, and consistency.

add emoji: add relevant emoticons for a fun touch.

for example, in the following video, the user first uploads notes to canvas to generate blog content, then adds examples to the first paragraph to enrich the expression and polish the title, and finally adjusts it to "college reading level". in less than a minute, the rough and scattered notes turned into a fully structured blog post.
