Bug Report: Canvas Bug — Chat Responses Overwriting Existing Documents
`Steps to Reproduce`
Steps to Reproduce:
Open a canvas/document in ChatGPT.
Begin writing your own content in the document.
Ask ChatGPT a separate question in the chat, unrelated to the doc content.
Instead of responding in the chat, ChatGPT injects the answer into the canvas, replacing or altering existing text.
`Expected Result`
ChatGPT should always respond in the chat unless explicitly instructed to edit the document. My work in the document should never be overwritten unless I request it.
`Actual Result`
Responses are routed into the open canvas without permission.
Content I’ve written in the document gets deleted or replaced.
This makes it impossible to safely work on long-form writing while asking clarifying questions.
`Environment`
Model: GPT-5 (ChatGPT Plus) Platform: Web (Desktop) Browser: Chrome 139 Date of Issue: Ongoing (as of August 2025)
