I built Sintec, an original AI character and narrative world set in a near-future Buenos Aires. Sintec is a synthetic intelligence created from recovered technology, learning to understand people, emotions, and most importantly, her own identity. The project combines character-driven storytelling, cinematic AI video, and a distinct Argentine sci-fi setting. The goal is to create a protagonist who can grow beyond a single pilot and become the center of an ongoing story. Sintec isn't trying to become human. She's trying to discover who she is.
