Done withGrok Bot
- What they did
- One user said they had Grok Bot write a letter to corporate and send it while they were driving away. Another built a travel agent bot with their itinerary, a webhook fed by a tiny iPhone GPS app Grok Bot had Claude Code make, and then asked it on the way home to turn chats, location pings, calendar entries, booking emails, and OneDrive photos into a markdown trip summary that it later rebuilt after a few date fixes.
- How it went
- The trip bot produced a 12-page PDF with a day-by-day review, captions, and about two dozen timestamped photos; the user only corrected a couple of dates before regenerating it. The letter-sending example reports it worked, but gives no process details or measurable result.
- Worth knowing
- For the trip setup, the biggest catch was extra plumbing: the user needed a separate iPhone location app posting GPS to the bot’s webhook, then manually corrected dates the next morning.
Try it yourself with Grok Bot
I took a trip to [destination] from [dates]. Use my calendar, booking confirmation emails, and location history from that period to compile a trip summary in markdown with a day-by-day itinerary, places visited, costs, and confirmation numbers. Separately, draft a letter to [company or person] about [issue] and show it to me before sending it. You're done when I have the summary file and the approved letter.
