A high school English teacher found a $450 paint sprayer listed for $100 on Facebook Marketplace — knowing nothing about paint sprayers.
- On-site, ChatGPT walked him step by step through priming the pump and checking the intake valve, letting him test the machine in the seller's backyard while she patiently waited.
- At home, it produced a supplies list and guided a deep clean, filter and part swaps; he can now take the sprayer apart and reassemble it.
- His point: YouTube videos are for fixing things you already own, not for personalized, real-time troubleshooting in a stranger's backyard — that's where ChatGPT shines.
