Unlocks over 140 distinct animations, costumes, and interactive toys through active browsing. Provides voice-enabled or text chat with custom personas and markdown support.
Why it works
Operates completely locally ensuring total data privacy with zero cloud latency. Utilizes lightweight WebAssembly and selective DOM truncation to maintain minimal CPU overhead.
