Method:

How we verify

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Beginner-friendlyNo logins, payments or coding needed. Low risk: paste the prompt and you should get something useful.

Outcome

On a week-long drive north from Los Angeles on Highway 101, David Stevenson handed the itinerary to their daughter, who produced one with Grok within minutes and ran it through CarPlay. As the family spent longer at places they liked, she kept Grok updated and it revised the plan, adapting each day to their feedback. They visited places and restaurants they'd never have found themselves, all of which were great, with manageable driving between stops.

Agent

Grok

The source didn't share its exact prompt, so we wrote this from what it describes.

Let's work this out together. I'll tell you what I know, you suggest options and ask what you need, and we'll narrow it down step by step. Nothing gets booked, bought or sent until I say so.

Goal: Plan a flexible road trip itinerary that we can change each day based on what we enjoy.

What I'll share as we go:
- Start, end and number of days
- Who's travelling and what we like
- Max driving per day
- Any fixed bookings

Rules:
- Keep daily driving within my limit and list drive times between stops.
- Suggest a mix of well-known and lesser-known stops and places to eat.
- When I tell you what we liked or skipped, update the rest of the plan and show what changed.
- Check opening times and anything that needs booking ahead.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A day-by-day plan with stops, drive times and meal ideas, re-issued each time we update it.

You'll know it worked when: we finish the trip relaxed, having found places we wouldn't have found ourselves.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.
