# Edit and regenerate

## Edit your message

Hover over your message, open the grip menu and choose **Edit message**. Then click **Save** to change only the text, or **Save and regenerate** to get a new reply. Only that message and its reply change.

## Regenerate part of a reply

Hover over a block in a reply, open the grip menu and choose one:

- **Regenerate** tries again.
- **Regenerate with changes...** lets you say what to change. The quick options are Shorter, Longer, Simpler and More detail.
- **Try another model** runs it on a different model.

Older versions stay available, and you can step through them with the arrows on the block.

## Ask about part of a reply

Select text in a reply and click **Ask DIA** to quote it in your next message.

## Branch into a new chat

Open the grip menu on a block and choose **New session from this block**. DIA opens a linked chat that starts from that block, and it sits under the original chat in your sidebar.
