About Karma Builder
Karma Builder is an intelligent assistant designed to help users engage meaningfully and organically in Reddit discussions. Using AI, it analyzes the context of a thread and generates high-quality, relevant replies perfectly tuned to the user’s chosen tone (informative, funny, contrarian, etc.). To ensure generated responses aren't simply copy-pasted and accurately engage with dynamic single-page applications, Karma Builder leverages accessibility-driven key event simulation to physically type out the generated response naturally on behalf of the user, mimicking human interaction rhythms.
