See what ChatGPT, Claude, Perplexity and Google's AI can read on your site
Type a site and Citewren reads its robots.txt, llms.txt, homepage and sitemap the way AI crawlers do. You get a 0-100 score and a grade, a bot-by-bot table showing which AI crawlers your robots.txt lets in (the ones that train and the ones that search and cite), whether your llms.txt is valid, which schema.org types the page declares, and a plain-words list of problems. It takes about 10 seconds. Pro adds the fix for each issue, a 15-page crawl from your sitemap, a ready llms.txt draft and robots.txt rules to paste.
How the 0-100 score is built
| Area | Points | What is checked |
|---|---|---|
| Citation bots | 30 | robots.txt access for OAI-SearchBot, ChatGPT-User, Claude-SearchBot, Claude-User, PerplexityBot, Perplexity-User, Googlebot, Bingbot |
| Structured data | 20 | schema.org JSON-LD types on the homepage |
| llms.txt | 15 | present, Markdown (not an HTML catch-all), # title, > summary, link lists |
| Sitemap | 10 | found and URL count |
| Open Graph | 10 | og:title, og:description, og:image |
| Basics | 10 | title, meta description, canonical link, html lang |
| Indexable | 5 | no noindex on the homepage (meta tag or X-Robots-Tag) |

Why teams pick Citewren
- Checks the technical layer AI search depends on: if robots.txt blocks OAI-SearchBot, Claude-SearchBot or PerplexityBot, those engines cannot read or cite you.
- Separates training crawlers (GPTBot, ClaudeBot, CCBot) from search and citation bots, so you can block one group and keep the other.
- Validates llms.txt against the llmstxt.org format: title, summary line and link lists, and catches a catch-all HTML page served at /llms.txt.
- Free daily checks; the $19 pass matches the cheapest one-time report we found and Monitor costs less than Otterly's $29 Lite plan.
- Plain-words issues with the fix, not just a score.
How it works
- Open Citewren and type your site's address.
- Read the score, the AI crawler table and the issue list (about 10 seconds).
- Fix robots.txt and publish llms.txt; with Pro, copy the ready rules and llms.txt draft, then re-check.
FAQ
What is an AI search readiness check?
A technical check of whether AI search engines and assistants can reach and understand your site: robots.txt rules for their crawlers, llms.txt, structured data, sitemap and Open Graph.
Why not Otterly.AI or Semrush?
They track how often AI answers mention your brand, from $29/month (Otterly Lite) and $139/month (Semrush). Citewren checks the technical side that comes first: whether the bots can read you at all. Many teams use both.
Why not Lumind?
Lumind's GEO report is also $19 and adds visibility scoring across engines. Citewren's $19 pass covers 30 days of Pro reports, with robots.txt rules and an llms.txt draft to paste.
Does a high score guarantee AI citations?
No. It means nothing technical is stopping AI search from reading your site; being cited also depends on your content and authority.
Does blocking GPTBot hurt ChatGPT search?
No. GPTBot is OpenAI's training crawler; ChatGPT search uses OAI-SearchBot and ChatGPT-User, which Citewren lists separately.
