Please add a conversation tree or branching feature inside ChatGPT.

The current chat structure is mostly linear. Every new message is added after the previous one. This works for simple conversations, but it becomes difficult when a user wants to explore a side topic without interrupting the main conversation.

The idea is to allow users to create a branch from any message in a chat. A branch would be a separate sub-conversation connected to the original point. The user could explore the side topic inside that branch, then return to the main conversation and continue from where they left off.

Why this is important:

Many real conversations are not linear. People often start with one main topic, then need to explore smaller related topics. In the current system, these side discussions make the original chat long, messy, and harder to follow.

Example:

A user is planning a trip to Italy in one ChatGPT conversation. The main conversation is about the overall travel plan: cities, dates, budget, hotels, and transportation.

In the middle of the chat, the user wants to go deeper into one side topic: “What are the best museums in Florence?”

Currently, if the user asks many questions about Florence museums, all of those messages are added to the same linear chat. The main travel-planning conversation becomes cluttered.

With conversation branching, the user could create a branch from the Florence message. Inside that branch, they could discuss museums, tickets, opening hours, and walking routes. Then they could return to the main Italy trip conversation and continue planning hotels or transportation without losing the original structure.

Another example:

A user is learning Python. The main chat is about learning basic programming. At one point, the user gets an error message. Instead of filling the main learning chat with a long debugging discussion, the user could open a branch from that error message, solve the bug there, and then return to the main lesson.

Suggested behavior:

Users can create a branch from any message.

Each branch works like a separate sub-chat.

Branches remain connected to the original parent message.

Users can switch between the main chat and branches.

Branches can have short titles or labels.

The conversation could be displayed as a tree, with the main conversation as the trunk and side discussions as branches.

Why this matters for ChatGPT:

ChatGPT is not only used for quick questions. Many users use it for long-term thinking, studying, writing, planning, programming, research, and decision-making. These workflows often naturally split into multiple paths. A tree-based conversation structure would make ChatGPT much more organized, especially for complex or long conversations.
