radar353: CalendarGPT
Dec 2023
A chained-LLM tool that turns a pasted URL into a calendar event – built for CS50, years before Apple shipped the same idea in iOS 26.
OpenAI API
Paste a URL, get a calendar event. A chained-LLM tool built as my CS50P final project – and, quietly, years ahead of the feature Apple introduced in iOS 26.

A minimal interface – closer to a search box than a form. Paste any event URL; the OpenAI API extracts the relevant details and outputs an ICS file ready to drop into any calendar.
