ChatMapper

ChatMapper is a visual editor built specifically for nonlinear dialogue and event sequences, mapping conversations as a tree graph where each player choice leads to a different branch. Its AI collaborator suggests new branches, generates dialogue variations, and fills in placeholder lines to prototype a conversation fast, running on your own model provider keys through an approve-before-apply flow rather than auto-committing text. A built-in conversation simulator lets you play through the logic to catch dead ends and broken branches before it ships, and a screenplay generator exports scripts for voice talent.
