Apple Calendar Generator

Apple Calendar Generator is a web-based tool that leverages the OpenAI GPT API to convert natural language event descriptions into .ics (iCalendar) files compatible with Apple Calendar and other calendar applications. Users enter their own GPT API key (stored locally in localStorage), optionally select a timezone, and describe their event in plain text to generate a downloadable .ics file. The tool runs entirely client-side in the browser and is hosted as a GitHub Pages project by developer Henry Yuan (onehumanbeing).
