Fork a thread

Select Fork on a message to start a new thread containing every message up to and including that one. The original thread is untouched.

Use it to try a different line of questioning without losing what you already have, or to carry on from someone else's thread that you cannot write in.

Fork from a message

1. Open the thread from the Threads page.
2. Hover the message you want to branch from.
3. Select Fork.

AI Studio makes a new thread named after the original with - Fork appended, and opens it. Send your next message there.

The new thread stands on its own. Nothing you do in it changes the original, and the original shows no sign that it was forked.

Threads you did not write

Opening someone else's thread gives a read-only view. The page explains it: you can fork from any message and continue in your own copy. Use Fork, then Continue in the new thread.

If it did not work

• Fork is not on the message: open the thread from the Threads page rather than from the sidebar list.
• The fork stops short of where you wanted: fork from the later message. A fork keeps everything up to the message you chose, and nothing after it.
• The fork has no attachments: attachments are not carried into a forked thread. Attach them again. See Attach files to a message.
• You cannot type in a thread and there is no Continue button: you are not its author. Fork it.
