Cover image for In a single night I

In a single night I was able to build this awesome diary PWA using by applying my very own framework architecture with Google AI Studio. I'm actually using the app myself for the first time in my career, like I'm the user of my own craft, can't believe I finally made it. Now I can think of how I can sell it, but for you who are reading here you can also enjoy the app for free at the link: https://easyaichatdiary.vercel.app/

Cover image for I was able to build

I was able to build a working AI generated RPG app in 2 days with Google Gemini 3 and my very own framework asasvirtuais (https://github.com/asasvirtuais/asasvirtuais-framework). I used Airtable to store the data and generate images and text based on user provided definitions of the game elements (cards, characters, missions).
