Pythos is a free AI mathematics and physics tutor built by LANZAR to help students master STEM concepts with rigor, clarity, and confidence. Functioning as a free AI tutor, AI mathematics tutor, and AI physics tutor, Pythos emphasizes conceptual understanding over simple answer generation.
Traditional chatbots frequently produce unchecked mathematical output or offer quick shortcuts that bypass the learning process. Pythos takes a fundamentally different pedagogical approach: it actively guides learners through problem-solving steps, verifies derivations against deterministic calculation safeguards, and helps students build genuine intuition.
Whether working through algebra, calculus, or classical mechanics, Pythos provides a dedicated learning environment accessible to any student.
- Step-by-Step Tutoring: Provides structured, step-by-step guidance and progressive hints that lead students through derivations without simply handing them the answers.
- Reasoning Verification: Audits algebraic manipulations, calculus derivations, and physical formulas using deterministic calculation kernels and independent Computer Algebra System (CAS) verification to prevent mathematical hallucinations.
- Interactive Math & Physics Visualizations: Generates dynamic visual models—including 2D function graphs, projectile trajectories, force diagrams, and physical simulations—to help learners visualize abstract equations and relationships.
- Study Guides & Reference Materials: Includes curated, built-in study guides covering high school through undergraduate topics in algebra, calculus, and Newtonian mechanics.
- Free & Accessible: Fully free to use with no subscriptions or paywalls, built with dedicated accessibility considerations including assistive MathML support, screen-reader polite live regions, and keyboard-navigable tools.
Pythos features real-time, interactive geometric instruments and universal visual inspectors directly in the conversational canvas. When working through trigonometric reference angles, calculus derivatives, or coordinate geometry, Pythos automatically renders verified visual models that students can manipulate dynamically.

When a student asks to simulate or solve 2D kinematics problems (e.g. "Simulate projectile motion" or "A ball is thrown at 20 m/s at 45°"), Pythos mounts a classical physics instrument directly in the dialogue:

- Real-Time Trajectory Tracing: Dynamic 2D canvas plots the parabolic trajectory, apex height marker, and ground impact coordinates.
-
Dynamic Physics Controls: Classical sliders for Launch Velocity (
$v_0$ ), Launch Angle ($\theta$ ), and Gravitational Acceleration ($g$ ). -
Etched Metric Tablets: Instantaneous recalculation of Flight Time (
$T$ ), Maximum Height ($H$ ), Total Range ($R$ ), and orthogonal velocity vectors ($v_{0x}, v_{0y}$ ). - High-Arc vs Flat Ballistics: Real-time trajectory morphing and comparison (e.g. steep angles with increased apex vs shallow long-range arcs).
