An AI answer preview shows how an AI assistant like ChatGPT or Perplexity would answer a question using your page, and how likely that page is to be cited. Paste your key section and the question you want to win. The free RankFirst tool simulates the assistant's answer, scores your citation odds, and checks your content against the GEO rules that decide what gets quoted.
How to use it
Paste the section a searcher would land on
Drop in the key section or summary of your page, up to 500 characters. Paste the part that actually answers a question, not the whole post, because that is the passage an assistant would read and quote.
Add the question you want to win
Type the question a user might ask an assistant, phrased the way they would say it. Leave it blank and the tool infers a likely question from your content. Matching the searcher's wording is half of getting cited.
Read the preview, then fix the failed checks
You get the exact sentence an assistant would quote, a citation score from 0 to 100, and a pass or fail on each GEO-readiness check against your real text. Fix the failed checks, preview again, and watch the score climb.
What is generative engine optimization?
Generative engine optimization, or GEO, is the practice of writing and structuring a page so AI assistants quote it when they answer a question. It is the answer-engine cousin of SEO: instead of ranking a blue link, you are trying to become the sentence ChatGPT, Claude, Perplexity or Google's AI Overviews lift into their reply. The mechanics are different because the reward is different. A search engine sends a visitor to your page. An answer engine reads your page and repeats part of it to someone who may never click through, so the whole game is making one clean, self-contained sentence that an assistant can lift and attribute. Answer engine optimization, AEO, and LLM optimization all describe the same idea. This tool shows you the outcome of that work before you publish: the actual sentence an assistant would quote, and whether your page is quotable enough to be chosen.
How do AI assistants decide what to cite?
When you ask an assistant a question, it does not read the whole web. It fans out to a search index, pulls a handful of pages, and looks for the cleanest passage that directly answers the question. Three things decide whether that passage is yours. First, can it reach your page at all: if your robots.txt blocks the assistant's crawler, you are invisible before the contest starts. Second, is there a self-contained sentence that answers the question without needing the paragraph around it. Assistants quote one line at a time, so a sentence that starts with a word like it or this is hard to lift because the subject is missing. Third, does the line carry something specific and checkable, like a number, a date or a named fact, because assistants favour concrete claims they can corroborate. The preview above scores your page on exactly these signals.
What makes a page citable by AI?
A citable page reads like a set of clean answers, not a wall of narrative. The strongest pages lead with a direct one-sentence answer under a heading phrased the way people actually ask the question, then back it with specifics. Keep each sentence able to stand on its own, so it still makes sense when an assistant quotes it in isolation. Include at least one concrete fact, number or date, because that is the detail most likely to be lifted and the easiest for the assistant to verify against other sources. Keep sentences short and to one idea each, so the assistant has a clean unit to extract. Stay crawlable and keep the quotable line free of links. None of this requires special markup or an AI text file: it is clear, factual writing, structured for extraction.
How this AI answer preview helps you get cited
Most GEO tools give you a score and a list of fixes, but they never show you the thing that actually matters: the sentence an assistant would quote and whether it would choose you at all. This preview does. It simulates the answer an assistant would write using your page, so you can read the exact line it would lift and judge whether that line makes your case. It scores your citation odds from 0 to 100 and marks each GEO-readiness check against your real text, not a generic rubric, so a failed check points at a specific sentence to fix. Rewrite, preview again, and watch the score move. It is the same method RankFirst runs on every post it publishes for you, so your blog is written to be quoted by AI from the day it goes live.
Questions, answered
How do I get cited by ChatGPT?
Get cited by writing the answer, not just the article. Lead each section with a single, self-contained sentence that answers the question directly, then back it with a specific fact or number. Keep the assistant's crawler unblocked in your robots.txt, and phrase your headings the way people ask the question. ChatGPT lifts the cleanest line it can find and attributes it, so the clearer and more quotable that line is, the better your odds. Paste your section above to see the exact sentence it would quote.
What is generative engine optimization?
Generative engine optimization, or GEO, is the practice of structuring your content so AI assistants quote it when they answer a question. It is the answer-engine version of SEO: instead of ranking a link, you become the sentence ChatGPT, Perplexity or Google's AI Overviews lift into their reply. It rewards clear, self-contained sentences, specific facts and question-shaped headings. Answer engine optimization and LLM optimization describe the same goal, getting your page named as a source in AI-generated answers.
How do AI assistants decide what to cite?
They fan out to a search index, pull a handful of pages, and look for the cleanest passage that directly answers the question. A line gets picked when the crawler can reach the page, the sentence stands on its own without the surrounding paragraph, and it carries a specific, checkable detail like a number or a named fact. Assistants quote one sentence at a time and prefer claims they can corroborate, so self-contained, factual sentences win over vague narrative.
What makes a page citable by AI?
A citable page leads with a direct one-sentence answer, keeps every sentence able to stand alone, and includes at least one concrete fact, number or date. Short, single-idea sentences give the assistant a clean unit to lift, and a question-shaped heading helps it match your line to the query. Stay crawlable and keep the quotable sentence free of links. No special markup or AI text file is required, just clear writing structured so a single line can be extracted and attributed.
Will my page show up in AI search?
There is no way to guarantee it, but you raise the odds by being reachable, clear and specific. First, make sure your robots.txt does not block the assistant's crawler, or you are invisible from the start. Then give each key question a direct, self-contained answer with a concrete fact in it. Assistants pick the cleanest, most quotable line they can find, so a page written answer-first is far more likely to be cited than one that buries the answer in narrative.
Is this AI answer preview tool free?
Yes, completely. There is no account, no email and no usage cap, so you can preview as many pages and questions as you want. The tool simulates how an assistant would answer using your page, scores your citation odds and checks your text against the GEO rules that decide what gets quoted. RankFirst builds these free tools as a sample of what the product does at scale, then writes and publishes AI-ready content to your blog every day.
