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.

More writing features

Helperbird is one of the most helpful tools I've ever used. It has so many great features that not many other apps or software have. The free version can be installed and stay forever on your browser. Other companies don't always give you access for free or give access for free forever. When you do get access to the Pro version or other paid plans, you expand your opportunity to read and stay focused better. One of the other great things about Helperbird is their support service. They have a video for every single feature that you can use. They are simple and helpful videos that make the learning process a lot easier. In addition, they have great live chat support. They are super nice and helpful. They always encourage people to give suggestions on how to improve Helperbird. Why is this important? It shows they really care about people with disabilities or people in general.
