AI claim checker
Paste an AI-written draft to find the sentences that claim things you may not be able to back up: tests nobody ran, clients, your own data, numbers without a source, statements credited to Google, quotes and offers you don't make. It runs in your browser, so your text isn't sent anywhere.

What it looks for
These are the claims an AI writer can make without anything behind them. Each flagged sentence is one to check, not an error.
- Testing and reviews (for example, We tested 12 tools…)
- Keep it only if a named person really ran the test or used the product. An AI writer can't test anything.
- Clients and case studies (for example, One of our clients saw…)
- Client stories need a real client who agreed to be described. Remove or replace any result you can't show.
- Your own data or research (for example, Our internal data shows…)
- Only claim research you actually did, and say how you did it.
- First-hand experience (for example, In our experience…)
- Readers can only trust experience a real person had. Say who, or rewrite it as general advice.
- Numbers without a source (for example, 64% of readers…)
- Link each figure to where it comes from. AI writers often make up exact-looking numbers.
- Claims about Google (for example, According to Google…)
- Check it against Google's own documentation and link to the exact page. AI writers can invent Google statements, metrics and even documents.
- Offers and downloads (for example, Download our free checklist…)
- Keep an offer only if you really provide it, and link to the page where people get it.
- Quotes (for example, “…,” says an industry expert)
- Check the person really said it, and link to where they said it.
Why check for these claims
Google's guidance on helpful content asks: “Does your content clearly demonstrate first-hand expertise and a depth of knowledge (for example, expertise that comes from having actually used a product or service, or visiting a place)?” An AI writer has no first-hand experience, so when a draft claims tests, clients or experience, a person has to confirm it or take it out.
Made-up client stories can also break consumer protection rules. In the US, the FTC's rule on reviews and testimonials, announced in August 2024, covers testimonials that “misrepresent that they are by someone who does not exist, such as AI-generated fake reviews, or who did not have actual experience with the business or its products or services.”
Rankonpilot's own AI writer is told not to make these claims. The editorial policy lists them.
What it can't do
- It reads wording, not facts. A flagged sentence may be true, and a claim worded differently won't be flagged.
- It works on English text.
- It doesn't tell you whether a draft was written by AI, and it doesn't look up sources for you.
Questions about the checker
Is my text sent or stored anywhere?
No. The check runs in your browser. The text you paste isn't sent to Rankonpilot or anyone else, and the page doesn't save it.
Does it detect AI-written text?
No. It flags claims a person has to confirm, whoever wrote the draft. It's built for AI drafts because an AI writer can make these claims with nothing behind them.
What should I do with a flagged sentence?
If it's true, keep it and back it up: name who ran the test, link the source, or get the client's permission to describe their results. If it isn't true, rewrite it as general advice or delete it.
Can I paste HTML?
Yes. Paste plain text or the article's HTML. With HTML, a number that already links to a source isn't flagged.
