What you are watching is not a concept trailer. Tiny Stories starts with one dramatic seed, then compiles it into a playable AI drama runtime. The backend generates the cast, player role, hidden leverage, failure conditions, and the first scene before the player ever makes a move. During play, each choice becomes persisted state. The interface keeps the options readable, but still lets the player write a custom tactic when the fixed choices are not enough. A separate advisor channel can reason over the current run, without taking control of the story. Then the ending compiler turns the path actually played into a label, highlights, alternate branches, and a replayable artifact. For a portfolio reviewer, the point is the system design: React product UX, FastAPI runtime, typed contracts, LLM orchestration, persistent state, and a demo path that can be inspected rather than merely believed. It is a small game, but a complete case study in building AI products with constraints.
