Feature Request: Sub-chats / Anchored Follow-up Questions

I’d like to suggest a small ChatGPT feature that I think could make conversations much easier to follow, especially when learning.

The idea

When ChatGPT gives a response, allow users to start a small sub-chat attached to a specific part of that response.

For example, imagine ChatGPT gives me a 10-line explanation.

I understand everything except something mentioned in line 3.

Currently, I can select the text and use “Ask ChatGPT”, but the question becomes part of the main conversation. I then have to go down to the bottom of the chat, ask my question, read the answer, and then go back to the original response.

Instead, I’d like to be able to ask the question right there, attached to line 3.

For example:

3. A protocol is a set of rules that devices follow to communicate.

:speech_balloon: Sub-chat

Me: What exactly is a protocol?

ChatGPT: Think of it like a common language and set of rules that computers agree to follow when communicating.

Then I could collapse that sub-chat and continue reading the original response.

Why I think this would be useful

The important part is that these would not become normal messages in the main conversation.

If I have three small doubts about three different parts of one answer, I could have:

Main response

  • Line 3 → Sub-chat

  • Line 6 → Sub-chat

  • Line 9 → Sub-chat

The original conversation stays clean, while every follow-up remains connected to exactly what I was asking about.

This would be particularly useful for:

  • Learning technical subjects

  • Understanding unfamiliar words

  • Reading long explanations

  • Asking questions about code

  • Studying from ChatGPT

  • Understanding individual steps in a process

UI idea

It doesn’t have to make the interface complicated.

A selected piece of text could have an option such as:

Ask about this → Start sub-chat

Once created, the sub-chat could appear as a small expandable section or icon attached to that piece of text.

It could also be collapsed so the original response remains completely clean.

The main idea

I’m not asking for a completely separate chat system.

I’m imagining something closer to:

Main Chat → ChatGPT Response → Specific part of response → Small anchored conversation

The key is that the follow-up stays where the question originated, instead of moving the discussion to the bottom of the main chat.

I think this could be a relatively small UI feature that would make ChatGPT much more natural to use for learning and exploring complex answers.

TL;DR: Let users start a small, collapsible conversation directly from a specific sentence, paragraph, code block, or part of a ChatGPT response. The follow-up stays anchored to that content instead of becoming a new message in the main chat.

I used AI to create a shorter title.

Thank you. It sounds better now.

I strongly support this proposal. I actually arrived at exactly the same problem independently while using a long ChatGPT conversation.

One aspect of the proposed solution would be particularly valuable to me: the ability to insert a follow-up question directly at the point in the conversation where the question arises.

For example:

Main conversation → ChatGPT gives a detailed explanation → user goes back to a specific paragraph → “Ask a follow-up here” → question and answer appear directly at that position → the original conversation continues below.

In other words, I would like the conversation itself to become non-linear, rather than forcing the user to jump to the bottom of the chat and refer back to an earlier passage.

A possible UI could offer:

• Ask here – insert the question and answer at this exact position.
• Start sub-chat – create a collapsible conversation anchored to this passage.
• Branch from here – continue the conversation as a separate branch.

The crucial point is that the user should not have to copy/paste the original text or write “regarding what you said above…”.

For long research, learning, technical and brainstorming conversations, this would make ChatGPT much easier to use.

A complementary feature such as “Show all follow-ups/references to this message” would also be very useful.

This is not really a request to bring back Canvas. It is a request to make the conversation itself navigable and non-linear.
