In ChatGPT and Codex
Add Inflation Calculator from the plugin directory in ChatGPT or Codex, then ask things like “What is $100 from 1980 worth today?”, “How much did eggs cost in 1980?” or “Which countries had the most inflation since 2000?”. Answers come with a chart and the official source.
It covers 22 currencies, with US figures back to 1800, everyday item prices, spending categories like food and housing, and US Social Security raises. Every number comes from official data, never from the AI's memory. No sign-in needed.
Where the numbers come from
The US Bureau of Labor Statistics consumer price index and average prices, the OECD, the World Bank and IMF, and the Social Security Administration. The current year is an IMF forecast until the final figure is published.
