Specifically, I used ChatGPT to brainstorm APIs, refactor and comment C# editor code, draft documentation/changelogs, and generate/example JSON snippets. I also used AI-assisted design to create some marketing media (icon/cover/overlay templates), which I then edited and finalized. All AI outputs were manually reviewed, rewritten where needed, and fully tested by me.The package itself does not include or require AI/ML at runtime—no model weights, no data collection, and no calls to external AI services. All in-package code and assets are original or properly licensed, and a ThirdPartyNotices/License file is included where applicable. (A future Pro edition may add optional LLM-based JSON generation, but that is not part of this submission.)
