ChatMapper vs ink and Inky

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 a month, billed annually. ChatMapper Cloud supports current Chrome, Edge, Firefox, or Safari; the separate offline Desktop 1.9.1 app is Windows-only.

ink is a text-first scripting language for branching game narratives, with logic and code placed within the story text. It is designed mainly for professional game development, though it can also be used to write and share choice-based interactive fiction. The companion Inky editor lets writers create, test, and export stories in one app. Its play pane updates while a story is being written, it highlights errors as they appear, and it can jump from a divert to its target. Inky exports stories as JSON or as a web page ready for customisation. The editor runs on Linux, macOS, and Windows. For Unity, an integration plugin recompiles ink files during editing and provides a previewer inside the Unity Editor; the maker also points to Inkpot, a container for using ink within Unreal Engine. ink, Inky, and the Unity plugin are free under the MIT license.
