Branching and rollback let you undo changes and explore different directions without losing your work. Both are available in Agent Mode only.

​
Rollback

Rollback takes your conversation and sandbox back to a previous point. The agent’s sandbox, your canvas, and all generated files are restored to exactly how they were at that message.

​
How to rollback

1

Hover over a previous message

Find the message you want to go back to. Hover over it to reveal the action buttons.
2

Click Rollback

Click the Rollback button. The conversation rewinds to that point. All messages after it are removed.
3

Continue from there

Your sandbox and canvas are restored to the exact state they were in at that message. Send a new message to continue in a different direction.
Example: You asked the agent to build a pricing page for your fitness studio. It built one with vertical cards. You then asked it to make them horizontal, but you preferred the original. Rollback to the message before the horizontal change. The vertical version is back, and you can try a different approach.

​
What you cannot do with rollback

  • You cannot rollback in Chat Mode (Agent Mode only).
  • You cannot rollback to a message that has no checkpoint. Checkpoints are created after each agent response.
  • You cannot undo a rollback. Once you roll back, the later messages are gone. If you want to keep both versions, use branching instead.

​
Branching

Branching creates a new, independent chat starting from any message in your current conversation. The new chat gets its own copy of the sandbox, so you can take it in a completely different direction without affecting the original.

​
How to branch

1

Hover over a message

Find the point where you want to fork the conversation.
2

Click Branch

Click the Branch button. A new chat opens with the conversation up to that point and a fresh clone of the sandbox.
3

Take it in a new direction

The original chat stays exactly as it was. The new chat is independent. You can try a completely different approach.
Example: You built a landing page for your coffee subscription service. You want to test two different designs: one minimal with lots of whitespace, and one bold with dark backgrounds and large images. Branch at the point where the basic structure is done. Now you have two independent chats, each with its own sandbox, where you can explore both directions.

​
What you cannot do with branching

  • You cannot branch from Chat Mode (Agent Mode only).
  • You cannot branch without a message checkpoint (the sandbox needs a snapshot to clone).
  • You cannot merge branches back together. Each branch is a fully independent chat.

​
When to use which

Before making a big change (like restyling an entire website or restructuring a presentation), branch first. If the change does not work out, your original is untouched in the other chat.
