Physics AI is an online physics solver designed to help users understand the equations, units, and concepts of physics problems step by step. Users can ask questions by entering text problems or uploading photos and receive step-by-step explanations.
In terms of main capabilities, Physics AI covers multiple physics topics, including kinematics and motion, circuits and Ohm's law, and forces and Newton's laws. It can break down motion problems to solve for displacement, velocity, and acceleration; analyze series and parallel circuits to calculate current, voltage, and resistance; and transform complex word problems into clear free-body diagrams to help calculate net force and acceleration. In addition, it can generate kinematics graphs (such as position-time graphs), harmonic motion waveforms, and thermodynamic PV diagrams, as well as draw schematic diagrams of complex mechanical devices such as multi-pulley systems, optical lens benches, or circuit diagrams, and display vector arrows such as tension, friction, and gravity components.
In terms of use, users first paste a problem or take a photo, and Physics AI can recognize messy handwriting, printed text, and diagrams such as free-body diagrams or circuit diagrams. Users can then choose between two modes: Tutor mode provides step-by-step conceptual explanations and helps build mental models through guiding questions; Solver mode quickly provides precise numerical calculations and final answers, suitable for checking homework. Both modes help users not only obtain answers but also see the complete derivation process of how formulas are selected, rearranged, substituted with values, and unit conversions are performed.
Applicable scenarios include: quickly checking answers during exam preparation; learning step by step when mastering concepts in depth; and when needing visual understanding of abstract concepts such as magnetic fields and rotational dynamics, users can ask it to "draw it" for instant visualization. It covers a wide range of content from high school kinematics to university quantum mechanics and is suitable for AP, IB, A-Level, and introductory university physics courses, covering classical mechanics, electromagnetism and waves, thermodynamics, and modern physics. It can serve as a 24/7 study companion for verifying homework, debugging calculation errors, or explaining concepts.
In terms of limitations, Physics AI is mainly trained for high school and first- or second-year university physics problems. For very advanced, highly specialized, or research-level problems, it is recommended to use it as an aid and still confirm results with an instructor or textbook. Photo recognition works better in clear lighting and when the problem is in focus; blurry, too dark, or hard-to-read handwriting may lead to inaccurate results. Problems are best written in English with standard physics symbols and SI units; short problems in other languages may also be usable if the equations and numbers are clear. It is designed as a study companion, not a shortcut to bypass learning. Different schools and teachers have different rules, and their policies should be followed; unless exam rules explicitly allow it, it should not be used during graded tests or quizzes. It is not an official provider for any specific examination board. Pricingaspects include a free account with bonus credits, as well as three professional plans: 3 permanent credits (3 conversations) including image uploads (up to 6); 300 credits/month (300 conversations); 1,000 credits/month (1,000 conversations), including visual explanations, priority replies, advanced AI models, and feedback priority. Users can upgrade, downgrade, or cancel at any time, and changes take effect from the next billing cycle. Specific prices are not currently provided.
