Branchlight

Your dialogue can read perfectly and still be structurally broken.

A choice points nowhere. A scene can never be reached. An ending disappears during a rewrite. Branchlight catches those problems while you write—before they become bugs inside your engine.

Build scenes, connect choices, play the result instantly, and watch the Story Health panel verify every path.
