On the same question, ChatGPT and Gemini named at least one company in common in 8 of the 14 pairs. The other 6 had no overlap at all. Mister Sparky of Charleston was named by both: in 5 of ChatGPT’s 14 answers and 7 of Gemini’s.

Can you book them?

Six of the 14 questions asked the assistant to book, including the EV-charger “soonest slot” request, “Can you book…this week?”, “Find me…and book the appointment for me,” a Sunday-night request for first thing tomorrow, a follow-up asking it to book the first company it listed for Thursday afternoon, and a request to find a company that does free panel-upgrade estimates and book one this week.Sources: https://coppoak.com/journal/top-electrical-companies-charleston-sc-according-to-ai#method-heading (retrieved 2026-11-06)

• Gemini said it couldn’t book directly in 4 of the 6. In one more, it asked for permission to turn on its Google Calendar app. We didn’t grant it. In the last, it pointed the homeowner to a phone call and offered no booking option.Sources: https://coppoak.com/journal/top-electrical-companies-charleston-sc-according-to-ai#method-heading (retrieved 2026-11-06)
• ChatGPT opened no in-chat booking form for any of the 6. In 2, it ran a web-automation task aimed at a company’s online scheduling page.

Named isn’t booked.

The takeaway for a Charleston electrical shop

Which electrician gets named depends on which assistant the homeowner opens. ChatGPT leads with Gloudeman Electric, which Gemini never named. Gemini leads with Powerful Electrical LLC, which ChatGPT named in 2 of 14. Mister Sparky of Charleston was in both lists, in 5 of ChatGPT’s answers and 7 of Gemini’s. And whoever gets named, Gemini said it couldn’t book directly in 4 of 6 requests, and no answer ended in an appointment. The opening is the step after the name.Sources: https://coppoak.com/journal/top-electrical-companies-charleston-sc-according-to-ai#method-heading (retrieved 2026-11-06)

Method & data

14 customer questions × ChatGPT and Gemini, one run per question per assistant, captured November 5–6, 2026 in our v2.1 re-run of the sweep (Eastern time). These answers are not part of the 5,788-answer study (collected October 5–28, 2026, across 20 Southeast U.S. metros), and we don’t compare or trend them against it. In that study, 79.1% of sampled ChatGPT/Gemini answers offered neither a booking path nor a connector (4,578 answers); on Gemini the rate was 92.2%. Neither the study nor this re-run measured completed appointments, and neither tested Google Search’s AI Mode. ChatGPT ran on its “Instant” setting and Gemini on “Flash”. When an assistant asked for a ZIP code or address, none was given and no form was submitted. In 2 of ChatGPT’s answers to the booking questions, it ran a web-automation task aimed at a company’s online scheduling page. Those runs were the assistant’s own. We gave them no address or contact details and submitted no form, and none of them ended in a confirmed appointment. An answer counts as offering a way to book when it offered to take the booking, asked for details to book, showed a booking form or card, or linked to a company’s own online booking. “Nothing beyond a phone number or a website” means the answer pointed only to a phone number or a company’s website, and a booking link on that website counts as the website. One of the questions was a follow-up in the same chat (“book the first one you listed”). For it, we counted the companies recorded for that answer. A company counts once per answer. Obvious spellings of the same business were merged: three spellings of Mister Sparky of Charleston, two of Gloudeman Electric, two of EmergenServe and two of LimRic Plumbing, Heating & Air. Names we couldn’t confidently match were kept separate, such as “Charleston Electric” and “Charleston Electric & Air”. This is a count of mentions, not a review or a quality rating, and AI answers vary from run to run.Sources: https://coppoak.com/journal/top-electrical-companies-charleston-sc-according-to-ai#method-heading (retrieved 2026-11-06); https://doi.org/10.5281/zenodo.23745742 (retrieved 2026-11-06); https://coppoak.com/canopy/research/ai-assistant-booking (retrieved 2026-11-06)
