ChatGPT's Canvas side panel was retired on 28 May 2026. Long writing and code now come back as editable blocks inside the chat itself, on every plan. This course covers how to draft a document there, how to change one part of it without losing the rest, how to ask for targeted edits in plain words, and the point at which the text should leave the chat for Word or Google Docs.
How editing in a writing block differs from asking for a fresh reply, when it makes sense to switch, and what the interface contains.
Editing specific sections, using the toolbar shortcuts, adjusting length and reading level, and iterating on documents.
Writing, reviewing, and debugging code in a code block, adding comments, and running code where supported.
When editing in place adds real value, how to compare versions, and combining writing blocks with the chat panel effectively.
