ChatMapper
What it is
ChatMapper is a browser-based workspace for designing, simulating, validating, and delivering branching conversations. Its node-based graph supports dialogue, choices, actors, variables, conditions, scripts, media, and links between conversations. The simulator runs Lua logic and checks for broken links, dead ends, and undefined variables. An AI collaborator can suggest structured edits for human review, with accepted changes saved as revisions. ChatMapper imports .cmp, XML, Arcweave, Twine, articy:draft, and CSV files, and exports JSON, Unity XML, SCORM, xAPI, Yarn, HTML, and LearnBrite. Its canonical JSON can be used with Unreal, Godot, and custom engines; the site also describes Unity and Yarn exports. Listed uses include games and interactive stories, learning, immersive experiences, and AI character roleplay. The free plan permits one editor, three projects, and 300 nodes per project, with core exports and commercial use permitted. Paid plans start at $19 a month, billed annually. ChatMapper Cloud supports current Chrome, Edge, Firefox, or Safari; Desktop 1.9.1 is a separate Windows-only offline application.
