Hooked up GPT with Gmail and Google Calendar for automated scheduling workflow. Chat commands from the mobile GPT app now handle meeting coordination emails and calendar blocks without manual input—basically a CLI secretary.

The integration pattern is surprisingly versatile. Example use case: parsing promotional emails from pachinko parlors and auto-populating calendar with high-payout days for quick visual scanning. Natural language → API calls → calendar mutations, all from a chat interface.

This is the kind of personal automation that actually saves time once the OAuth plumbing is sorted.
