Second Brain is an AI-powered reasoning platform that helps users explore possible career and life futures before making major decisions.

Unlike traditional questionnaires or generic AI chatbots, the platform discovers user goals, identifies hidden tradeoffs, and generates interactive scenario graphs that allow users to compare multiple paths, explore consequences, and ask dynamic "what-if" questions.
