AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

OpenSheet uses generative AI for optional artwork only. This is disabled by default.

Pre-rendered: the decorative art that ships with the app — character portraits, race and class backgrounds, creature illustrations, interface icons and stat-panel frames — was produced with OpenAI's image models, as were the application icon and this store page's artwork. All of it is decoration, every family of it can be switched off in Settings, and a new installation shows none of it by default.

Live: if you supply your own OpenAI API key, two optional features call OpenAI directly — generating a portrait for one of your characters, and generating a character concept. Both are off by default and neither does anything without a key you entered yourself. Nothing leaves your computer otherwise.

No rules content is AI-generated. Every rule, statistic, feat, spell, item, monster and table comes from the published 3.5 Edition SRD source material and the PCGen data set. The app is built so the book always wins.
