2. AI-assisted media
The following service images were generated using Google Gemini Pro (Imagen-based image generation) as a starting point and subsequently retouched and integrated into the TwoStack design system manually in Adobe Photoshop.
Legal classification: Under current Austrian copyright law, pure AI outputs are not considered copyright-protected works because they lack human creative input. The manual editing in Photoshop, however, establishes an independent creative contribution to the final image. The Google Gemini terms of use permit commercial use of the outputs.
