AI brand fact checker: Is what AI says about you right?
This free AI brand fact checker shows whether what AI says about you is right. It reads your site and your Knowledge Graph entry, asks ChatGPT, Claude and Gemini about your brand, and marks each fact in their answers right or wrong, with the cited pages behind any wrong one.
Your facts and what each engine said
The first column holds your facts, read from your site and your Knowledge Graph entry. Change any of them and the grades update at once, at no cost.
Where the wrong facts may come from
For each wrong value, we opened the pages that engine cited and looked for it. A page that carries it is the first one to get corrected.
How to fix what AI gets wrong about you
The steps below come from this check, most useful first, then the Organization schema for your facts.
What we read about you
Each engine's answer
The question each engine got, its whole answer, the pages it cited and the searches it ran.
What an AI brand fact checker is
An AI brand fact checker compares what AI engines say about a brand with the facts the brand publishes itself.
Ask ChatGPT, Claude or Gemini about a small company and the answer often sounds sure while getting the founding year, the city or the phone number wrong. This AI brand fact checker takes your facts from your own site and your Google Knowledge Graph entry, asks the three engines one fixed question about you, and grades every fact in their answers, so you see what each engine gets right, gets wrong or doesn't know.
How the AI brand fact checker works
The AI brand fact checker works in five steps, and you could check each one by hand.
- It reads your site. Our server opens your home page and the About, Contact and Pricing pages it links to. It takes your facts from their schema.org markup first, then from the pages' own words and their phone and email links.
- It looks up your Knowledge Graph entry. The same lookup as our knowledge panel checker finds the entry with your website and fills the gaps your site leaves.
- It asks the engines one question. ChatGPT, Claude and Gemini each get the same question with web search on: your brand name, your website and the facts to answer, never the facts themselves.
- It grades every fact. A year must match, people are matched by name, a place by its city and state, and a phone number by its digits. Your description is compared by its key words, so different wording is marked as worded differently, not wrong.
- It looks for the source of each wrong fact. For every wrong value, it opens the pages that engine cited and shows which of them carry it.
Why AI gets brand facts wrong
AI gets brand facts wrong for a handful of reasons, and each one has its own fix.
Old or copied directory listings
Old or copied directory listings are the most common source. An engine that searches the web reads a business directory, a data broker's page or an old press release, and repeats a phone number or an address you changed years ago.
Training data that stopped earlier
Training data that stopped earlier explains a wrong fact that no cited page shows. A model learns from a snapshot of the web, so a new owner, a move or a new price can be missing until the engine searches, and some answers don't search at all.
Another company with your name
Another company with your name can get mixed into the answer. Engines join facts from pages about different companies that share a name, which is why this check gives them your website along with the name.
Facts your site never states
Facts your site never states leave the engines to guess. If no page says when you were founded or who runs the business, an engine fills the gap from wherever it can, or says it doesn't know.
How to correct what AI says about your brand
To correct what AI says about your brand, fix each fact where the engines read it, then give them one clear version to repeat.
- State each fact once, plainly. Put your founding year, founders, city, phone and email in plain sentences on your About and Contact pages, not only in images, forms or scripts.
- Add Organization schema. The checker writes the markup from the facts you confirm. Paste it into your home page, so search engines and AI crawlers read the same facts your visitors do.
- Correct the pages that carry a wrong fact. Start with the pages the engines cited, and with the profiles you control, such as your Google Business Profile, LinkedIn page and Crunchbase entry. Then ask directories and publishers to update theirs.
- Check again after a few weeks. An engine that searches can pick up a corrected page once it is crawled again. What a model learned in training changes only with a newer model.
How to read brand fact results
To read brand fact results well, keep in mind what the checker can and can't tell apart.
- Your facts set the bar. Every grade compares an answer with the first column. If our reader picked up the wrong value from your site, type the right one and the grades change at once, at no cost.
- One check is a sample. AI answers change from one run to the next. Check again on another day before you act on a single wrong fact.
- Wording isn't graded as wrong. Your description is compared by its key words, and a low match is marked worded differently, because a correct description can use other words.
- A wrong fact with no source. When none of the pages an engine cited carry the wrong value, it may come from the model's training data or from a page it read without citing.
- Sites that turn servers away. Some sites refuse requests from servers or build their text with JavaScript. Then type your facts into the first column yourself.
AI brand fact checker questions
These AI brand fact checker questions come up most: what it costs, what it asks and what it keeps.
Is the AI brand fact checker free?
Yes, the AI brand fact checker is free. Without signing in you can check 2 brands a day, and with a Google sign-in, up to 25 a day.
Each check asks each engine once. Reading your site, your Knowledge Graph entry and the pages the engines cite costs nothing, and an answer saved in the last 24 hours comes back free.
Which AI engines does the brand fact checker ask?
The brand fact checker asks three AI engines: the ChatGPT app with search, Claude through Anthropic's API with web search on, and Gemini through Google's API with Google Search grounding.
You can untick any engine before a check. Google AI Overviews and AI Mode aren't included, because their answers stay inside Google Search.
What question does it ask the engines?
It asks the engines one question: what they know about your brand, with your website named so they look up the right company, answered in short labeled lines.
The question names the facts to answer but never gives them, so no engine can copy them from the question. Facts of your own are added as extra labels.
Where do my facts come from?
Your facts come from your own site first: the schema.org markup on your home, About, Contact and Pricing pages, then the words on those pages and their phone and email links. Gaps are filled from your Google Knowledge Graph entry.
You can change any fact in the first column after a check, and the grades update at once.
What does the brand fact checker keep?
The brand fact checker keeps each AI answer and each page check for 24 hours, so a repeat check costs nothing. From a page it keeps only the facts it found, never the page itself.
The facts you confirm and the grades stay in your browser. Without a sign-in, checks are counted per connection and the counts are deleted after a few days. A Google sign-in keeps your email address and name. The About page lists everything the site keeps.
How is it different from paid brand monitoring tools?
It is different from paid brand monitoring tools such as Profound's FactCheck, which grades answers against a knowledge base on Profound's paid plans, and Waikay's Fact Tracker, where you mark each fact right or wrong by hand.
This checker is free, takes your facts from your own site and Knowledge Graph entry, grades them without your help, and runs one check at a time instead of tracking prompts on a schedule.
Can I check a competitor's brand?
Yes, you can check a competitor's brand the same way: type its name and website. The facts then come from its own site, so the grades show what the engines get wrong about it.
