About
Physics AI is an online physics solver designed to help students understand equations, units, and concepts through step-by-step explanations. Users can type a problem or upload photos of diagrams, circuits, and handwritten notes to get instant assistance. The platform offers both a Solver Mode for quick numerical checks and a Socratic Tutor Mode that uses guiding questions to build deep conceptual understanding.
Built for high school, AP, IB, and college-level students, the tool covers a broad syllabus ranging from classical mechanics and thermodynamics to electromagnetism and modern physics. It breaks down complex word problems, visualizes mechanical setups, and translates abstract equations into clear kinematic graphs to help students master tricky coursework.

Validate audience choices with actual data
Stop guessing where your buyers hang out. Run an audience research query (SparkToro-style) on your actual segment and surface the unexpected sites and vernacular they engage with. The "indie hackers also frequent Kotaku" kind of finding is what changes how you write headlines, pick metaphors, and choose which platforms to invest in.
There's a play for whatever you're stuck on.
