Calculator Tools

Calculator Tools generates simple web apps from a chat description, such as calculators, trackers, converters, editors and mini-games, and publishes them at a shareable link. It is meant for teachers, office workers and hobbyists who want a quick tool without a developer.

You describe what you need, then edit and remix the result through further chat messages until it works the way you want. Finished apps go live immediately, anyone with the link can use them, and most keep working offline while saving small amounts of data in the browser.

There is also a set of official custom GPTs inside ChatGPT for building apps, plus helpers for automatic programming, grading and accessibility checks. A public gallery lets you browse and reuse apps other people have made.
