Projects
A project groups chats on one topic. All chats in the project use the same instructions and, if you like, one Company Brain. Projects are personal: only you can see your projects.

Putting chats into a project
New chat in project at the top of the project page starts a chat that uses the project's instructions and Brain.
To assign an existing chat, use Chat options and Add to project in the sidebar. No project in the same menu takes it out again. In an open chat you can also use the Project button in the message field, which shows the current project's name, and Move to project. The menu item and the button appear once you have at least one project.
The project page lists all assigned chats under Chats in this project, most recently edited first.
How instructions and Brain work
The instructions apply to every message in every chat of the project. If you change them, the new version applies from the next message, in existing chats too. The same goes for a chat you move into the project later.
The project's Brain is added to the brains you select in the chat itself. How a Brain answers in the chat is described under Brain in chat.
Renaming and deleting
The commands are in the Project options menu, in the sidebar next to the project and at the top of the project page. Rename changes only the name; instructions and Brain stay.
Delete removes the project. The chats in it are kept and simply leave the project. From then on they no longer use its instructions or its Brain.
