For over a decade ChatMapper has been a standard for branching dialogue: 104,000+ creators, native Unity Dialogue System import, used by teams at Kaplan, USC and THQ. In 2026 it’s a browser-based, AI-native studio that keeps every bit of that heritage and adds collaboration, simulation, validation and modern delivery.
ChatMapper isn’t a legacy desktop tool anymore. It’s ChatMapper Cloud: the same trusted format and Unity-native heritage, now in the browser with real-time collaboration, an AI copilot, live Lua simulation, deterministic validation, and export to Unity, SCORM, xAPI and immersive 3D. Your old .cmp and XML projects import directly.
Open a link on Mac, Windows, Linux or Chromebook and your whole team is in the same project. No installs, no license servers.
Organizations, roles, live presence, autosave, full revision history and conflict protection replace passing project files around.
Real Lua simulation and deterministic validation, an AI copilot that proposes reviewable edits, and export to Unity, Yarn, SCORM, xAPI, a standalone HTML player and immersive 3D via LearnBrite.
ChatMapper Cloud imports legacy .cmp, .cmpkg and XML projects, plus Arcweave, Twine and articy, and the canonical JSON format is public, with an MIT reference parser. The heritage is intact; the ceiling is much higher.
Every import shows exactly what carried over and flags anything it could not translate before it touches your project. Nothing is dropped silently, and canonical JSON export means you can always leave.
Yes, very much so. ChatMapper is now ChatMapper Cloud, a browser-based, AI-native studio for branching dialogue used by 104,000+ creators, with the same canonical format and native Unity Dialogue System import it’s always been known for.
The desktop app defined the category and native Unity import. ChatMapper Cloud is its modern successor: same format and heritage, now in the browser with collaboration, AI assistance, real-time simulation, validation, and export to Unity, SCORM, xAPI and immersive 3D. Existing .cmp/.cmpkg/XML projects import directly.
Yes. ChatMapper Cloud imports legacy .cmp, .cmpkg and XML projects, so nothing you built is stranded.
