ChatGPT Canvas: what replaced it, and how to write and edit now

ChatGPT Canvas was a separate editing space that opened beside the chat, so you could write and revise a document with ChatGPT side by side. OpenAI has since phased Canvas out of its current models. The same kind of work now happens in writing blocks: editable drafts inside ChatGPT’s replies that you can change directly or ask it to revise.

In this guide, you will learn what Canvas was, what replaced it, and how to use writing blocks to draft and polish your own writing. If you are brand new to ChatGPT, start with our guide on how to use ChatGPT.

What was ChatGPT Canvas?

A normal chat is a bit like passing notes back and forth. Every change means a fresh reply, and you end up scrolling to find the latest version. Canvas fixed that by giving your document its own space, more like a shared page you and ChatGPT could both work on.

You could type straight into the draft, highlight a sentence and ask for help with that part only, use quick shortcuts such as changing the length, and step back to earlier versions.

What happened to Canvas?

In 2026, OpenAI announced that Canvas would no longer be available in its newer models. Writing and coding help moved into the replies themselves, through writing blocks for text and code blocks for code. Paid users could keep using Canvas on some older models for a while, but the last of those models was due to leave ChatGPT in August 2026, so for almost everyone Canvas is now gone.

So if you have followed an older tutorial and cannot find Canvas, nothing is wrong with your account. The feature has changed, and the good news is that the core idea of editing with ChatGPT rather than starting over is still there.

What is a writing block?

A writing block is an editable box inside ChatGPT’s reply that holds a draft, such as an email, a social post, or a document. When ChatGPT writes something you are likely to revise or reuse, it may place it in one of these blocks.

Inside a writing block, OpenAI says you can:

• Select the text and edit it yourself
• Ask ChatGPT to revise a selected part, or the whole draft
• Open longer pieces in a full-screen editor with more room to work
• Undo or redo recent changes made by the AI
• Use common formatting such as bold, italics, lists, and checklists
• Save supported drafts to your Library to come back to later

Your edits are saved with the conversation, and ChatGPT uses your latest version when you ask a follow-up.

How do you write and edit with writing blocks?

1. Ask for a draft. Describe what you are writing, who it is for, and the tone you want. Writing-style requests are the ones most likely to come back in a writing block.
2. Read it through once. Note what works and what does not before changing anything.
3. Make your own edits. Fix facts, names, and anything that does not sound like you by typing straight into the block.
4. Ask for targeted changes. Select a paragraph and ask ChatGPT to shorten it, warm it up, or make it clearer, rather than regenerating everything.
5. Go full screen for longer pieces. Essays and reports are easier to shape with more space around them.
6. Copy or save the final version. Take it into your email, document, or post once you are happy.

Here is a prompt to try:

Draft a short email to my child's school asking if they can join the
after-school art club mid-term. Keep it friendly and under 120 words.
Put it in a format I can edit, and ask me one question if anything
important is missing.

Once the draft appears, try selecting the middle sentence and asking for it to be more concise. Seeing only that part change is the moment this way of working usually clicks.

What are writing blocks good for, and what are they not good for?

Good for	Not so good for
Emails, letters, and messages	Heavily designed layouts or complex formatting
Blog posts, essays, and reports	Facts you have not checked yourself
Polishing tone and length	Replacing your own judgement about what to say
Revising one section at a time	Code, which goes in code blocks instead

Formatting is kept fairly basic, so if you need fancy layouts, finish the text here and do the design work in your usual document tool.

A few tips for better results

ChatGPT can sound polished while getting a detail wrong, an error known as a hallucination. Always check names, dates, and figures before you send anything.

It also helps to give ChatGPT a sample of your own writing so the draft sounds more like you. For more ideas on drafting, editing, and finding your voice with AI, read our guide on using AI for writing.
