SoundCharades is an AI-powered audio guessing game where every sound effect and original song is generated from scratch by ElevenLabs. Players listen to layered soundscapes and AI-composed riddle songs to guess movies, video games, countries, food, and more. The game's difficulty engine is built entirely on turbopuffer, using cosine similarity across 768-dimensional embeddings to dynamically select answer options based on semantic proximity. The closer the concepts are in vector space, the harder it is to tell them apart. Players can also generate custom quizzes on any topic in minutes, with new concepts instantly queryable in turbopuffer the moment they're created. No manual curation, no static databases, just vectors, sound, and AI.
