Most math input methods make you pick: a symbol-packed keyboard, or learning LaTeX from scratch.
Purr Math Keyboard just needs the name — type "fraction" or "integral" and tap to insert a real formula (fractions, exponents, nested roots, integrals, limits).
Tap Send and it drops into whatever you're typing — chat, notes, or AI chatbots. Great for asking ChatGPT a math question: it reads the formula image directly, no LaTeX needed.
