From a first question to a change in your code

One conversation in Murmur, start to finish.

Ask a question, as in any chat.
Each branch keeps its own context, and the map shows them all.

Sketch it out

Draw the rough shape on a board, then bring it into the conversation it belongs to.

Some things are quicker drawn: open a board and sketch it.
Claude answers about the sketch, on the branch it belongs to.

Notes beside the work

Sticky notes sit next to the branch they’re about. The model only sees one when you hand it over.

Drag one into the message box to hand it over.
Mark it done and it turns green.

Cut what the next turn carries

Sever a line and the turns above it stop being sent. The conversation stays as it was.

Pick up Sever and draw across a line.
Rejoin it whenever you like. Nothing is deleted.

Think it through, then do it

Take a branch into a Do conversation on your folder, and Claude Code builds what you planned.

When a plan’s ready, do the branch in a folder.
Every edit waits on a card, with its diff.
Allow it, and the change is made.

Back the next morning

Notes you picked out wait on the start page, and ⌘K finds them by what they say.

The next morning, the start page has what you meant to do.
⌘K finds a work item by what its note says.
It opens at the note, beside the branch it’s about.
