Why Claude and Perplexity describe your business differently

You ask ChatGPT to recommend a plumber in Liverpool and it suggests yours. You try Claude with the same question and it hedges. You ask Perplexity and it recommends two of your competitors. Same city, same question, same business — three different answers.

This isn't random. AI tools don't share a single database. Each one builds its own picture of your business from its own sources, and those sources don't always overlap. That's why you can appear confidently in one AI tool and be invisible in another.

By the end of this post, you'll know why ChatGPT, Claude, Gemini and Perplexity reach such different conclusions about the same business, and what to do so they all start telling the same story.

Why each AI tool sees you differently

Every AI tool answers questions from its own mix of evidence. The mix isn't the same across the four tools your customers are using.

ChatGPT relies heavily on its training data plus live web searches through Bing. Claude leans on its own training data and tends to stay quiet when it isn't sure of the facts. Gemini sits on top of Google's index, so it favours businesses that already perform well in normal Google search. Perplexity searches the live web every time a question is asked, and quotes its sources back at the reader.

That means your business is being judged four different ways. A directory listing that ChatGPT picks up might be missing from Perplexity. A review on a trade body site might shape Claude's answer but be invisible to Gemini. The result is four slightly different stories about the same business, told to four different audiences.

The freshness gap

Some AI tools work with information from months or years ago. Others read the live web. If you updated your address six months ago but old directories still list the previous one, an AI tool that relies on training data will quote the old address while a real-time tool will get it right. Customers don't see the difference. They just see one tool that knows where you are and one that doesn't.

The source gap

A garden designer in Norwich might be featured in a regional magazine, a Facebook group and three trade directories. One AI tool will weigh the magazine highly because it has a strong reputation. Another will lean on the Facebook posts because they were public and indexed. A third might skip both and rely on what your website says. Same business, different evidence, different answers.

What this means for your business

When your story changes from one AI tool to the next, customers get inconsistent recommendations. Some hear about you, some don't. Some get accurate details, some get an old phone number. AI tools also tend to be careful when they sense conflicting information — and when an AI tool hedges, your competitor often gets the recommendation instead.

When invisibility looks like a small problem

A kitchen fitter in Sheffield once told us they appear regularly in ChatGPT searches but had never been mentioned by Perplexity. They assumed Perplexity was a smaller tool and didn't matter. The reality: Perplexity users tend to be researching seriously before they commit. Being invisible there meant losing the customers who were closest to picking up the phone.

When the wrong answer looks correct

A physio in Cardiff was quoted accurately by Gemini but described as "permanently closed" by another AI tool because an old listing on a forgotten directory still showed those words. Customers reading that answer weren't going to call. The fix took less than an afternoon, but the listing had been costing them appointments for almost a year.

How to give every AI tool the same story

The good news is that you don't need to make each AI tool happy in a different way. They all reward the same thing: a clear, consistent story about your business that's easy to find and easy to verify. Working through your AI readiness score is a sensible way to spot where the story changes from tool to tool.

Make your facts impossible to misread

Pick one canonical version of your business name, address, phone number, opening hours and services. Write them on your website in plain text — not inside an image, not buried in a PDF. Use the same wording on your Google Business Profile, your social profiles and any directories you appear on. AI tools cross-reference these. Consistency builds confidence.

Use the words your customers use

Each AI tool tries to match the question being asked. If you describe yourself as offering "premium domestic plumbing solutions" but customers ask about "boiler repair near me", you're using language no AI tool will easily connect to the question. Rewrite your service pages in the words a real customer would type into ChatGPT or Perplexity.

Refresh anywhere you appear

Old listings keep selling the wrong story long after you've forgotten about them. Search your business name and find every site that still mentions you. Update them. The five minutes it takes to fix a stale directory entry can change what every AI tool says about you within weeks.

Common mistakes to avoid

• Testing only one AI tool. If you check ChatGPT and see yourself recommended, it's easy to assume the job is done. The other three platforms might be telling a very different story. Test all four before you decide where you stand.

• Trusting your website over the wider web. Your website is just one source. AI tools weigh outside sources — directories, reviews, news mentions — sometimes more heavily than your own pages. If your About page is perfect but external listings contradict it, the contradictions tend to win.

• Updating in one place only. Changing your opening hours on your website while leaving them stale on three directories tells AI tools you have inconsistent details. Inconsistency is treated as a warning sign. Update everywhere or expect mixed answers.

• Ignoring tools that look smaller. Perplexity has fewer users than ChatGPT, but its users are often closer to a buying decision. Being invisible in a smaller tool can still cost you real customers.

How long this takes and what to expect

You won't get every AI tool agreeing on your business overnight. AI tools refresh their information at different speeds. Some update their training data quarterly; others reflect web changes within days. So the answers you get this week may not match what customers see next month.

If you tidy up the highest-impact problems first — your website facts, your Google Business Profile and your most-cited directories — you should see noticeable improvement within four to eight weeks. Wider, deeper consistency tends to settle in around twelve weeks. The businesses that get there fastest are the ones who pick one version of their story and repeat it everywhere.

You now know why ChatGPT, Claude, Gemini and Perplexity tell different stories about your business, and you've seen what to do about it. The aim isn't to flatter each tool individually — it's to make sure they all have the same evidence and reach the same conclusion.
