I would appreciate a way to reply directly to individual paragraphs or sections within ChatGPT and Codex responses.
When I ask for several operations or discuss multiple topics, the response often contains a lengthy explanation for each point. To respond, I currently have to work through those points in the main message composer, copying or quoting passages and repeatedly scrolling between the response and my draft to make each reference clear.
My proposal is to let users add replies, clarifications, corrections, or additional instructions directly beneath the relevant paragraph or section. These contributions would remain visually distinct from the AI’s text and clearly linked to the passages they address, preserving that context when ChatGPT or Codex continues the conversation.
The preferred workflow would be to add comments across multiple sections, review and revise them, and then submit them together as a single follow-up. ChatGPT or Codex would consider those contributions together when responding or carrying out the requested changes. Sending an individual inline reply immediately could also be supported as an alternative.
For example, after receiving a response covering three proposed changes, I could approve the first, request a different approach to the second, and add a requirement to the third—placing each comment exactly where it belongs. I could then review all three comments before submitting them together.
Expandable/collapsible sections could further improve this workflow by making longer responses easier to navigate and allowing users to focus on one topic at a time.
This would make detailed, multi-topic conversations clearer and faster, reducing the need to copy, quote, and reconstruct the original response in the composer.
