Gas Wiser is an AI-powered fuel intelligence platform for US and Canadian drivers. Users input their vehicle from a real EPA fuel economy database, set home and work locations, and get auto-generated daily route costs. The Route Planner takes any origin and destination and produces a full AI analysis,  fuel cost, optimal fill-up stop, efficiency score, price outlook, and vehicle-specific driving tips. The Trip Planner handles multi-day road trips with per-leg cost breakdowns, fill-up strategy, and departure timing. Everything is form-driven,  no chat interfaces. Once a plan is generated, a single "Chat About This" button opens Claude with full context of that plan for follow-up questions. Powered by Claude Sonnet 4.7.
