Switch to Integrated Code and Writing Blocks for Faster Collaboration
Transition from Canvas to integrated writing and code blocks.
Adopt the new 'writing blocks' and 'code blocks' in GPT-5.5 instead of relying on the sunsetting 'Canvas' feature. These integrated tools allow for direct editing and refinement of long-form content within the chat interface.
The Scenario
You are working on a coding project or a long-form article and need to see the code/text updated dynamically. Use the new integrated blocks instead of looking for the 'Canvas' button.
Before & after
You would use the 'Canvas' interface to see side-by-side code and text editing. Managing separate windows or legacy views often took 20+ minutes for complex revisions.
Writing and coding functionality is now supported directly via 'writing blocks' and 'code blocks' in the main chat. You can edit and refine code in 5–10 minutes without leaving the conversation.
The Prompt
Write a Python script to [INSERT GOAL] and display it in a code block. Then, walk me through how to modify it to [INSERT CHANGE].
OpenAI is transitioning away from the separate 'Canvas' interface in newer GPT-5.5 models, moving that functionality into integrated writing and code blocks. Users should adapt their workflow to work within these inline blocks for drafting and debugging.
