A custom Grok Bot reportedly builds trip itineraries from email

A user says they built a Grok Bot that detects when they start planning a trip by watching their emails. It then creates an itinerary, collects flight, hotel and receipt details, and keeps a personalized to-do list. They say it has sent useful daily reminders about things to confirm, book or cancel, and can use its browser to finish tasks on their behalf. They can also share the itinerary with their wife or connect her agent to add details from her emails.
