What makes content quotable by AI engines
The grader scores eight things, weighted by how much they matter. Answer first: does the page answer its main question in the first 100 words? Quotable passages: are there self-contained sentences of 15 to 45 words with a specific claim? Evidence: figures with units, named sources, and links to authoritative sites. Structure: question headings, short sections, lists and tables. FAQ coverage, freshness (a visible or schema date within 12 months), authority (a named author, a bio, Person schema, an about page) and clarity (plain, readable sentences without filler).
How the grader works
It reads the page the way most AI crawlers do, as the HTML your server sends, without running JavaScript. Rules count the evidence, the structure, the dates and the readability, and pick out candidate sentences. A language model then ranks those candidates, finds the weakest passages and suggests rewrites. Every passage it returns must appear word for word in your text, or it is dropped, and every rewrite is checked so it cannot add a fact your page does not have. If the model is unavailable, the grade is made by rules alone and says so.
Before and after
A sentence such as “Our platform is the best solution on the market” gives an AI engine nothing to quote: no subject it can check, no figure, no source. A quotable version says what the product does, for whom, and how you know, using only facts you have, with a marked gap where your own figure belongs.
How to fix the common problems
Move the answer to the top and cut the warm-up. Replace general words with the specific thing. Put the figure, the date or the source in the same sentence as the claim. Turn your section headings into the questions people ask. Add a byline and a last updated date. For the technical side, such as whether AI crawlers can reach the page at all, run the free AI SEO Checker, and read how to get cited more often. To track whether AI engines actually quote you over time, see Noma's plans.
What it cannot see
We grade English text only for now. We cannot see content behind a login or a paywall, or text that only appears after JavaScript runs; paste the text instead. A high grade means your content is easy to quote. It does not mean an AI engine has quoted it, which depends on what else it finds about you across the web.
Common questions
- How do I optimize content for ChatGPT and AI search?
- Answer the page's main question in the first few sentences, then back it up. Write sentences that make sense on their own, with a clear subject and a specific claim. Put figures, dates and named sources next to the claims they support, use question headings and short sections, and show who wrote the page and when it was last updated. The grader checks each of these and shows which passages to fix first.
- What makes a passage likely to be quoted by AI?
- AI answer engines tend to lift passages that are self-contained, specific and verifiable: one or two sentences that define something, state a figure, or make a clear comparison, without relying on the paragraph around them. Sentences that open with "It" or "This", lean on words like "various" or "amazing", or make claims with nothing behind them are much harder to quote.
- Is this an AI content detector?
- No. It does not guess who or what wrote your text, and it does not check for plagiarism. It grades how easy your content is for an AI engine to understand, trust and quote, whoever wrote it.
- Does AI-readiness help Google rankings too?
- Much of it overlaps with Google's guidance on helpful, people-first content, such as answering the searcher's question clearly and making it plain who wrote the page. We cannot promise a ranking change, and nobody honestly can, but none of these fixes trades search performance for AI visibility.
- Will the rewrites add statistics or sources to my page?
- Never. Every suggested rewrite is checked against your own text, and any suggestion that brings in a number, a name, a link or a source your page does not already contain is thrown out. Where evidence would help, the suggestion leaves a marked gap, such as [add a figure you can source], for you to fill with something you can stand behind.
- How many pages can I grade for free?
- One page without signing up. Add your email and you can grade 5 pages a month, and you also unlock every rewrite, the questions the page could win, and the subtopics it is missing. Opening a page that was graded in the last 7 days shows the earlier result and does not use your allowance.
