JMR's BitLife v0.27.4

A life simulator that runs entirely in your browser. Pick your name, gender, country and seed, then live a life by clicking Age Up — the full game is premade and deterministic.

Optional AI (a local LLM for typed actions and Stable Diffusion art) is off by default and is not needed to play. You can switch it on under AI Features below — best on desktop with a recent GPU.

AI Features — optional, off by default

The full game plays without any AI. Turn this on to type free-form actions (local Gemma LLM) and generate avatar & scene art (local Stable Diffusion). These download large models and run on WebGPU — heavy on phones; leave off if the game crashes, freezes, or runs hot on mobile.
