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.

Equation Editor - A full-page space to write, read, and export equations.
Voice Typing - Dictate plain text on any website.
Maths Reader - Hear maths read aloud with Immersive Reader.

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.

This extension has been an absolute lifesaver. I have that fantastic combo of ADHD and Dyslexia while trying to go through college. I have difficulty keeping letters in order, seeing the gaps between words, and with ADHD on top, I lose focus A LOT. The immersive reader has been my new best friend. It drowns out the rest of the content on the page, changes the font to something I can read, and highlights the word as it reads to me. My eyes are forced to keep going in the right direction. I can slow down and pay attention to what I'm reading. I don't even have to go back and read the same paragraph 5 times to understand it! The screen overlay has been outstanding for eye strain and being able to distinguish between words and spaces. The custom font and spacing for research articles have been an enormous advantage! I can actually read the research papers now and not have this daunting 2 column fine print page to squint over.All around, this has been the best purchase I've ever had. I use this every day, with every assignment. I don't even struggle with story-based questions anymore. The immersive reader helps me read, listen, and understand the question all at once. I am still exploring what I can use this with and how it can make my academic career, and I keep getting impressed with every new way I find to use it. Seriously, try it out. You won't regret it at all. Even if you don't have dyslexia or ADHD, just try it out. You might find that it helps you understand the content you're trying to learn even better!
