TL;DR
What did Matt Dagley (@mattdagley) use Grok Bot for?
Store staff told a shopper what to buy for a MacBook Pro charging cable and power adapter, but the Thunderbolt cable seemed like overkill, so they asked Grok Bot, which said a USB-C charge cable would do.
What they did
At Best Buy, staff told them what they'd need for a MacBook Pro charge cable and power adapter. The Thunderbolt cable they suggested seemed like more than the job needed, so they asked Grok Bot for a second opinion.
How it went
Grok Bot said to get the USB-C charge cable instead, and they bought that.
"I saved about $45.00."

Worth knowing
- Give the exact laptop model and charger wattage, because the right cable depends on both. Check the answer against the laptop maker's own support page before you buy.
- Price check: Grok: free plan; Plus (The X Subscription): US$8/month, or US$6.67/month on a yearly plan (US$80/year) (checked Nov 2, 2026).
