[ChatGPT] Add lightweight Chat Groups / Collections independent of Projects

What variant of Codex are you using?

ChatGPT Web / ChatGPT App

What feature would you like to see?

Summary

Add a simple way to group selected ChatGPT conversations into a named collection, similar to how browser tab groups work.

Problem

Sometimes I have several specific chats that are related to the same task, topic, or period of work, but I do not want to move them into a Project.

Projects are more heavyweight because they can have shared context, files, and instructions.

I only want a lightweight way to visually group a few existing chats together.

Proposed Behavior

Users should be able to:

• Select multiple chats
• Create a named group or collection
• Add or remove chats from that group
• Expand or collapse the group in the sidebar

For example:

Chat Groups

▼ Research Project

• Literature review
• Experiment planning
• Results discussion
• Final write-up

▶ Project Ideas

▶ Travel Planning

The chats themselves should remain normal conversations. Grouping them should not change their context, memory, instructions, or Project membership.

Why Projects Do Not Solve This

Projects are workspaces.

This feature would only be for navigation and organization.

A useful mental model would be:

Project = workspace

Chat Group = tab group / collection of conversations

This is also different from grouping chats inside a Project, such as #30986. The idea here is to let users create simple chat collections for organization only, without changing the chat’s Project, context, files, or instructions.

Benefit

This would make it much easier to manage a large ChatGPT history when several conversations belong to the same temporary task or topic, without having to create a full Project for each one.

Additional information

No response

No Codex file, test, or entry point is named, and the request targets ChatGPT Web/App rather than this terminal repository. First verify whether this belongs in codex; if it does, identify the relevant UI surface and establish acceptance criteria for creating, editing, and collapsing chat collections without changing project membership.
