Read the full description

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. A real math keyboard, fully offline. Free on Google Play.

Could you build this?

Yes A custom keyboard that inserts formatted math templates by name and sends them to other apps is UI work on an existing keyboard or text-insertion framework, and the formula rendering is handled by an existing library such as KaTeX or MathLive.
