Arcweave is a modern collaborative branching editor. ChatMapper imports Arcweave projects and adds the production layer: real Lua simulation, deterministic validation, and export to Unity, Yarn, SCORM, xAPI and immersive 3D.
Pick Arcweave for a lightweight collaborative canvas. Pick ChatMapper when the scenario has to actually run: real Lua simulation, validation before delivery, and export to engines and LMS, and you still want browser collaboration. ChatMapper imports Arcweave, so trying it costs nothing.

Comparison reflects each tool’s documented capabilities and positioning as of July 2026.
Walk the player’s path with real Lua conditions and scripts, watch variables change live, and validate reachability and link integrity before delivery.
Unity, Yarn, SCORM, xAPI, HTML player and immersive 3D are built in, not an API you have to wire yourself.
Import from Arcweave, Twine and articy; export canonical JSON any time. ChatMapper is the neutral hub, not another silo.
Bring an Arcweave project into ChatMapper, then simulate it, validate it and export it to your engine or LMS, without rebuilding it.
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.
They target different needs. Arcweave is a clean collaborative canvas; ChatMapper adds real Lua simulation, deterministic validation, and production export to Unity, SCORM, xAPI and immersive 3D. If you need to prove logic works and ship it to an engine or LMS, ChatMapper goes further.
Yes. ChatMapper imports Arcweave projects and shows an import report before anything is written, so you can evaluate it against your real content.
Both start free. ChatMapper Creator is $19/mo; Arcweave paid seats are ~$15–25/mo. ChatMapper’s paid tiers include simulation, validation and full engine/LMS export.
Import your Arcweave project, prove it works, and ship it, free to start.
