I needed it for my players, but was unable to find anything suitable.</p> <p>Base prompt: </p> <blockquote> <p>I need a character sheet constructor based on R. Talsorian The Witcher TRPG. It must guide user step by step to fill out the character sheet and create a 1st level character. On the last step it must enrich all bios and other text-filled expressions via dice results and Gemini. Also, the application must generate portrait of the created character.</p> </blockquote> <h2> Demo </h2> <p><a href="https://aistudio.google.com/app/prompts?state=%7B%22ids%22:%5B%221kOfdkGaXaQoz7Pos4oiP0CEcH9Cbb8zy%22%5D,%22action%22:%22open%22,%22userId%22:%22116643616263792225037%22,%22resourceKeys%22:%7B%7D%7D&amp;usp=sharing" rel="noopener noreferrer">Link to the demo</a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fseyjzbsvvt5fmrabg3o5.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fseyjzbsvvt5fmrabg3o5.png" alt="Fully generated elf craftsman" width="800" height="764"></a></p> <h2> My Experience </h2> <p>Key insight: it's helpful only with the popular themes (not my scenario), otherwise it'll take a lot of time to describe what you need in details and provide sufficient context to Gemini.<br> There's still a lot to do, but the results are solid enough for future development. And it takes only 2 hours of my work with the Studio! </p> <p>I'm happy to add such tool as Google AI Studio to my SWE's "toolbelt"!</p> deved learngoogleaistudio ai gemini
