finallymet is a conversational dating service that replaces swiping with ai-powered matchmaking. users start by texting a number or opening a web link and get onboarded through natural conversation with a langgraph agent that extracts personality traits (ocean big five, dark triad safety screening) and preferences without forms or quizzes. The system uses a tiered multi-model architecture: claude haiku for fast routing, classification, and safety checks; claude sonnet for rich conversations and profile understanding; and claude opus 4.6 for the highest-stakes task: generating matches through bilateral nash scoring with llm-powered compatibility and dealbreaker analysis. matching is the one holy grail decision where maximum intelligence matters most, because you are choosing who someone meets in real life. and a human has to finally approve the match (usually an expert matchmaker)
