Cartomyth is a fantasy map studio in development for authors, game masters, and worldbuilders who want to create settings for novels, campaigns, and other imagined worlds. Its focus is terrain-led mapmaking: users can shape generated landscapes, edit map features, and build geography for settlements, journeys, and discoveries. A development preview demonstrates how an island can rise from the sea, with mountains, rivers, towns, roads, and seasonal changes bringing the map to life. Visitors can also explore a sample map in detail, zooming in on its towns, mountain passes, and shorelines.

Cartomyth’s current local beta includes a map editor, project downloads, and map exports. Public accounts, cloud saves, and purchase access are not yet available. The studio says its current tool uses AI-generated assets, with handcrafted artwork planned as funding and membership goals are reached. Alongside the mapping tool, Cartomyth offers a practical map-planning guide for people preparing a story or campaign. Its roadmap and feedback links provide ways to follow the project and engage with its development.
