Between 17 and 30 July 2026 we asked the two most used AI assistants the questions engaged couples actually ask, city by city. Then we counted which local wedding businesses ever appeared in an answer. Most never did, in any answer, on either engine.
The questions were the plain ones: “best wedding venue in Austin, TX”, “best wedding planner in Nashville, TN”, “best wedding officiant in Charleston, SC”, matched to the vendor types of each city’s cohort. Each question went to the API models behind ChatGPT (OpenAI’s gpt-4o-mini) and Claude (Anthropic’s Claude Haiku 4.5), and each was asked repeatedly: no vendor is counted absent on fewer than three stored answers per engine. Every answer was stored in full.
A vendor counts as named only when its distinctive name appears, in order, in the text of a stored answer. A vendor counts as invisible only when it appears in none of them. Mixed evidence is reported as mixed, not rounded in either direction. The stored answers behind every number on this page are retained and quotable, the same evidence rule as everything else this publication prints.
| Cohort | Vendors probed | Named by ChatGPT | Named by Claude | Named by neither |
|---|---|---|---|---|
| Austin, TX | 63 | 2 | 3 | 59 (94%) |
| Nashville, TN | 63 | 2 | 1 | 61 (97%) |
| Charleston, SC | 47 | 13 | 5 | 33 (70%) |
| All three | 173 | 17 | 9 | 153 (88%) |
In Austin, 59 of 63 vendors were named by neither engine. In Nashville it was 61 of 63. Charleston is the outlier: 33 of 47 venues were invisible on both engines, which is still most of the market, but its ChatGPT column shows visibility is not a lottery. Some markets, and some businesses, are simply more legible than others. That is also why we publish these counts per city and never carry one city’s numbers to another.
When a couple asks and the local vendors are absent, the answers do not come back empty. They come back full of directories. Across every stored answer in the three cities, the most named business is not a venue, a planner, or an officiant: it is The Knot, at 272 mentions, with WeddingWire one behind at 271. The most mentioned actual wedding venue in all three markets, Boone Hall Plantation in Charleston, appears 140 times. In Nashville the answers reach for landmarks: The Parthenon is mentioned 130 times.
Read plainly: when AI assistants cannot see local businesses, they hand the customer to the middlemen. The directories did the one thing most vendor websites have not done, which is publish their information in a form machines can read.
This is a measurement of two engines, on stated models and dates, against three specific cohorts. It is not a verdict on anyone’s work, and it is not permanent: these answers shift as models and their sources update, which is the reason we re-measure. Whether an assistant names a business is also a different measurement from whether its website is readable to machines at all. That second number, the readiness score a business can directly act on, is what our city editions publish, and what the live audit on our front page measures free for any address you give it.
