I got tired of Apple Mail not reliably flagging calendar events. And even when it did work, other events shared on iMessage, Slack, or random webpages still had to be manually copy-pasted into my Calendar. This got frustrating enough that I decided to claude-code a little utility to help me with this. Here's how it works:

You select any text on your Mac — an email, a Slack message, a webpage — right-click, hit "Add to Calendar," and it uses Gemini Flash to parse out the event title, date/time, location, and notes. You get an editable preview before anything gets saved to Apple Calendar.

It's bringing me joy everyday. Hope it helps you too!
