Physics AI is a tool designed to help students solve physics problems through two distinct modes. Solver Mode strips away explanation and delivers step-by-step calculations with final answers—useful when you're cramming or verifying your work. Tutor Mode uses the Socratic method instead, asking leading questions to build understanding rather than just handing over solutions. The platform handles image uploads, so you can photograph messy handwriting, diagrams, or circuit sketches and the AI parses them alongside typed problems. The real differentiator here is visualization. Beyond just solving equations, Physics AI generates free-body diagrams with vector arrows, mechanical sketches of pulley systems or optical setups, and graphs showing kinematic or thermodynamic relationships. This matters because abstract physics—magnetic fields, rotational dynamics, circuit loops—becomes concrete when you can actually see how forces interact or how a system behaves over time. The tool covers mechanics through quantum mechanics, so it scales from high school AP Physics to intro college courses. Pricing runs on a credit system. The free tier gives 7 credits monthly (7 conversations), while paid plans range from $5.90 to $11.90 monthly, offering 500 to 1,200 credits depending on tier. Annual subscriptions come with a 40% discount. All paid tiers unlock visual explanations, priority response times, and access to advanced AI models. The framing is honest about use cases—it's explicitly pitched for exam prep, homework checking, and late-night problem solving when human help isn't available. Whether that's a feature or a bug depends on your stance on AI-assisted learning.
