# Fork chat from a reply

In builder chat you can **Fork chat** from an assistant reply that has visible text. Hover the reply and use the branch control next to feedback.

Fork opens a new conversation that copies history through that reply (including earlier tool turns), plus the same mode, model, agent, and related chat settings. The original chat is unchanged. You continue in the new chat from that point, for example to try a different direction without losing the prior thread.

Availability notes: Fork chat is available in builder chat (full page and the page side panel). It is not offered in the end-user portal. You can only fork from an assistant message with visible text, not from guest replies, welcome messages, or tool-only turns.
