# Merge a branch back into your main chat

_Released January 17, 2026_

When a side conversation finds something worth keeping, merge it back into the main one, and preview exactly what will change first.

Choose how the content lands. AI-Assisted works it in properly with what is already there, and it is the right pick most of the time. Replace, Append and Insert do exactly what they say.

Nothing changes until you say so. Preview Merge shows the result side by side, with removals in red and additions in green, and only Confirm Merge makes it real.
