articy:draft X
A professional game narrative and content tool combining flowcharts, dialogue, object databases, templates, locations, variables, simulation, and engine export.
Why use it
As characters, quests, items, and branches grow, a shared object model reduces spreadsheet duplication and gives programmers structured content; the free edition permits commercial projects.
Where it fits
Use prototypes and playtests to find core experience problems while they are still cheap to fix.
What to check
The free edition limits each project to 700 objects, while collaboration and larger scopes require paid plans; modeling, engine import, and over-customized templates still add setup cost.
