ChatMapper

Overview

ChatMapper is a node-based tool for building branching conversations, checking their logic, and preparing them for different destinations. It is best suited to writers and teams who need structured dialogue that can move between narrative tools and game or learning engines. Its strongest case is the combination of visual authoring, simulation, and broad export options; its main trade-offs are the small included seat counts and the Windows-only offline desktop edition.

Key features

The graph can hold dialogue, choices, actors, variables, conditions, scripts, media, and links across conversations. That makes ChatMapper a fit for both simple branching stories and scenarios whose logic or structure needs closer management. Lua simulation and checks for broken links, dead ends, and undefined variables address a practical weakness of graph authoring: structural mistakes can be hard to spot by reading nodes alone.

An AI collaborator proposes structured edits for human review, with accepted changes saved as revisions. Supported provider integrations include OpenAI, Anthropic, ElevenLabs, HeyGen, and Synthesia, using customers’ own keys. Generative-media usage is billed directly by those providers, with no ChatMapper markup, so AI costs sit outside the subscription.

Imports include .cmp, XML, Arcweave, Twine, articy:draft, and CSV. Exports include JSON, Unity XML, SCORM, xAPI, Yarn, HTML, and LearnBrite. Unity and Yarn have direct export paths; the public canonical JSON format can also be used with Unreal, Godot, or custom engines. The MIT reference parser and exportable scenarios make portability a notable advantage for teams wary of locking their narrative data into one workspace.

Localization workflow and version history are supported. The Creator plan gives 90-day history, while Team includes full history. ChatMapper is presented for games and interactive stories, serious games and learning, immersive experiences, and AI character roleplay; the breadth is useful, though the best fit is work that benefits from explicit branches, variables, and conditions.

Pricing

The Free plan costs 0.00 USD per free and allows one editor, three projects, and 300 nodes per project, with core exports and commercial use permitted. It is a meaningful way for solo authors to build and publish modest projects, but project and node caps make it less suitable for larger or growing content. There is no free trial; the free plan is the ongoing entry point.

Creator costs 19.00 USD per month, billed annually. It removes project and node limits and adds Unity, Yarn, SCORM, xAPI, and LearnBrite exports, an AI copilot, localization, and 90-day history. This is the clearest fit for an individual creator who needs professional delivery formats or room to expand beyond the free caps.

Team costs 79.00 USD per month, billed annually, and includes three editors; extra editors cost $20 each. Roles and teams, live presence, full history, and priority support make it the relevant upgrade for collaborative work. The three included editors are a real ceiling for small teams, and larger groups should account for the per-editor charge.

Desktop Personal is 0.00 USD per free for one user and provides the offline Windows app for personal, non-commercial projects. It gives up commercial use and browser-based collaboration. Desktop Commercial is 35.00 USD per month, billed annually at $420 a year, for one professional user doing commercial and client work, with advanced exports and Windows Desktop 1.9.1. Desktop Team is 110.00 USD per month, billed annually at $1,320 a year, for three professional users with the same commercial scope and advanced exports. These plans suit Windows users who specifically need offline work; the desktop application is stable and maintained, while active development is in the browser product.

Enterprise & OEM has custom pricing and adds an OEM and white-label engine, custom integrations and exporters, SSO, security review, DPA, private deployment or on-prem options, an SLA, onboarding, and commercial support. It is aimed at organizations with deployment, security, or licensing requirements beyond the self-serve plans.

Platforms

ChatMapper Cloud runs in current Chrome, Edge, Firefox, or Safari. The product is listed for Linux, macOS, web, Windows, and self-hosted use, while the separate ChatMapper Desktop 1.9.1 application is Windows-only and runs fully offline. Choose the browser workspace for current development and cross-platform access; choose desktop only when offline Windows authoring is essential.

Who it's for

ChatMapper suits solo narrative designers, game writers, learning-content authors, and small teams who need to validate branching logic and export to established formats. The Free plan is commercially usable within its caps; Creator is the practical step up for a growing solo project, and Team is better when simultaneous editing, roles, or full history matter. It is a weaker fit for larger teams that need more seats without per-editor costs, or for authors who do not need structured branching and engine-oriented delivery.

Pros and cons

• Pros: Lua simulation and checks for broken links, dead ends, and undefined variables help catch logic and structure problems before delivery.
• Pros: A wide set of imports and exports, plus canonical JSON and an MIT reference parser, support moving scenarios between tools and engines.
• Pros: The free browser plan permits commercial use, while the free Windows desktop edition serves personal offline work.
• Cons: Free browser projects stop at three projects and 300 nodes each, and the plan includes only one editor.
• Cons: Team starts with three editors and charges $20 per additional editor, which can raise costs as a group grows.
• Cons: The offline desktop app is Windows-only, and active development is centered on the browser product.

Alternatives

For a broader category comparison, see Game Narrative Design Software.

Narrat is the stronger fit for readers seeking a free, open-source option with no restrictions on personal or commercial use. Yarn Spinner is worth choosing when an open-source workflow, Unity, Godot, or Unreal integrations, or a VS Code extension matters more than ChatMapper’s combined authoring and validation workspace. Narratyr is another freemium option for readers who want a visual editor and an open document format.

articy:draft X may suit authors who prefer its free tier of 700 objects per project and unlimited projects, or want a free trial of its paid subscription. Arcweave is an alternative for browser-based teams; its Basic plan allows unlimited members and guests but caps projects at three and items at 200 per project. Ren'Py is a free option for visual-novel authors working on Android, iOS, Linux, macOS, or Windows. ink and Inky is a free alternative for authors targeting Windows, macOS, or Linux. Naninovel is a paid alternative with a free trial across Android, iOS, Linux, macOS, web, and Windows.

Verdict

Choose ChatMapper if you need a visual branching-conversation workspace that can simulate Lua logic, flag structural faults, and export to game and learning formats. Its free commercial tier makes a sensible starting point, and Creator is the clear step up when caps or export needs become limiting. Look elsewhere if your group needs more than three editors without added seat costs, or if your priority is an offline desktop workflow outside Windows.
