Overview
ChatMapper is a browser-based workspace for designing, simulating, validating, and delivering branching conversations. Its visual graph handles dialogue, choices, actors, variables, conditions, scripts, media, and links across conversations. The simulator runs Lua logic and checks for broken links, dead ends, and undefined variables. An AI collaborator can suggest structured edits for review, with accepted changes saved as revisions. ChatMapper imports .cmp, XML, Arcweave, Twine, articy:draft, and CSV, and exports JSON, Unity XML, SCORM, xAPI, Yarn, HTML, and LearnBrite. Its canonical JSON can be used with Unreal, Godot, and custom engines; the maker also describes Unity and Yarn exports. Use cases include games, interactive stories, learning, immersive experiences, and AI character roleplay. The free plan allows one editor, three projects, and 300 nodes per project, with core exports and commercial use permitted. Paid plans start at 19.00 USD per month, billed annually. ChatMapper Cloud supports current Chrome, Edge, Firefox, or Safari; the separate offline Desktop 1.9.1 app is Windows-only.
