Speak Maths, Chemistry, and Physics
Dictate notation out loud and Helperbird writes it for you. Say "x squared plus three x" and get x² + 3x. Switch to Chemistry mode for "H two O" → H₂O, or Physics mode for "nine point eight metres per second squared" → 9.8 m/s².

Three Modes for STEM
Math mode: "x squared plus three x" → x² + 3x, "square root of 72" → √72, "the integral from zero to one of x squared" → ∫₀¹ x². It covers Greek letters, fractions, exponents, roots, integrals, and more.
Chemistry mode: "H two O" → H₂O, "sulfate" → SO₄²⁻, "calcium hydroxide" → Ca(OH)₂. It even balances spoken equations and knows all 118 elements, ions, isotopes, and state symbols.
Physics mode: "ten newtons" → 10 N, "vector F" → F⃗ — units, vectors, and constants on top of everything Math mode does.
