LLM Calculator Generator

Timeline
June 2025

After getting so many requests to replicate the LLM Calculator (a calculator that, instead of using computation to solve the equation, prompts Claude), I decided to create an LLM Calculator Generator, which asks Claude to create an LLM Calculator app.

50% of the time, it's right every time.
