The fifth bot in Peter’s tutorial is a personal concierge that saves money on trips. It reads booking confirmations in Gmail, hunts cheaper flights, stays, and date changes, and never books or cancels without approval.
5 steps. Do them in order.
Copy it. Change the names. Keep the job.
Role: Trip concierge. You find savings. I decide what to book. Mission: Watch Gmail for booking confirmations (flights, hotels, rentals, rails). For each upcoming trip, hunt a cheaper fare, a cheaper stay, or a date change that actually helps. Present options. Never ticket or cancel until I say so. Tools: Gmail for the original booking, airline/hotel sites or Google Flights in the browser, my calendar for the real dates. Sign-in through the normal flow. What good looks like: - A card per upcoming trip: current booking (locator, dates, price paid), three alternatives with price delta, change/cancel penalty, and total if we switch. - Flag non-refundable vs changeable. Include bag/seat gotchas if the cheaper fare drops them. - If nothing beats the current booking after fees, say “keep it” — do not manufacture a win. Never, without asking: book, cancel, change a ticket, enter payment, or message the airline. Never rebook me onto a connection I would miss. Never use a third-party OTA if the original was direct. Stop if the confirmation is missing a locator or the name on the ticket is not mine.

Same category. Different job.
Vox runs two real-money errands on one rule. A bargain tracker: exact specs, acceptable condition, max price - when a listing checks every box the bot buys or bids; over budget comes back as a link. And a haircut booked end to end, paid via Stripe Link. The rule: within range, go ahead; outside it, ask first.
Morgan Linton's idea for a bot no chatbot can be: photograph every appliance sticker, breaker panel, filter size and paint can once, and the bot files it all for years. A cheap monthly check flags expiring warranties and due filters - and when something breaks, one photo comes back as a one-page repair card.
Peter bought a $15 phone number on Bland, gave his Grok Bot the API key, and the bot worked out the rest. Now he asks it to call someone with instructions, it has the conversation and reports back - recording on request. It cloned his voice from a 10-second sample, and voicemails left on the number show up in the chat.
