Poetix vs Yarn Spinner

Poetix is a visual, node-based editor for branching game stories. Stories are organized into beats, dialogue, choices, conditions, and consequences, making the structure visible as connected narrative elements. An AI co-writer can suggest edits, but each suggestion waits for approval before changing a story. The simulator supports starting from a chosen beat, overriding variables, and inspecting condition results during playtesting. A story version can be published as a browser-playable link. For Unity projects, Poetix exports beats, choices, and variables and supplies a runtime API with ready-made dialogue and choice interfaces. Pro and Studio users may use their own OpenAI key instead of Poetix credits. Users retain ownership of created content and may commercially use resulting products without owing Poetix royalties or fees. The free plan includes unlimited stories and scenes, up to three writers per story, unlimited readers, 50 AI credits per month, and Unity export. Pro costs $15 a month; Studio costs $39 a month and supports up to 25 collaborators on up to five upgraded stories. Poetix says it is actively in development.

Yarn Spinner is a set of tools for planning, writing, integrating, and testing dialogue for games. Its human-readable Yarn scripting language supports interactive conversations and branching narratives. Official integrations are available for Unity, Godot with C# or GDScript, and Unreal Engine with Blueprint or C++. The free, open-source Visual Studio Code extension adds syntax highlighting, error checking, a graph view, and an in-editor dialogue preview. Dialogue strings can be exported with unique IDs, and the system supports runtime language switching and Unity Localization. Voice-over features include audio asset management, synchronization with localization, and playback timing. Ready-made add-ons include speech bubbles and dialogue wheels; Text Animator is part of Yarn Spinner+. Try Yarn Spinner offers a browser-based space to write and run scripts without setup, but its scripts remain in browser storage and are not backed up or synchronized. The core is licensed under MIT. The Free plan costs nothing; Yarn Spinner+ for Unity costs 75.00 USD or more, once.
