Best for checking what AI crawlers can reach on your site
llmstxt.studio runs a 41-check audit of how AI crawlers reach, read and quote your site, including which named AI bots your robots.txt lets in, and writes an llms.txt from your sitemap. Prices are in pounds, and the free account's 3 AI-written files and 50 citation checks never renew. Its citation check uses one AI search engine it doesn't name, so it's no tracker, and the vendor itself says no major AI provider has confirmed using llms.txt.
Who llmstxt.studio is for
- Fits if you want a free, detailed check of what AI crawlers can reach on your site
- Works for teams that want an email when an llms.txt or sitemap breaks after a deploy, from Pro
Who llmstxt.studio is not for
- Not for you if you want to track mentions across AI engines, as the citation check uses one engine it doesn't name
- Tight if you stay free: 3 AI-written files and 50 citation checks, once, never renewed
- Watch out: prices are shown in pounds even from the US, and the page description quotes $19.90 a month with no dollar price behind it
- Watch out: the vendor says Google Search doesn't read llms.txt and no major AI provider has confirmed using it
- Skip it if you need integrations or an API, as none are listed
Why llmstxt.studio gets a 2.4
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- BValue for moneyPro is £15.83 a month billed yearly, or £19.99 monthly, for 3 sites. That's roughly $21 to $27, a rough dollar figure, inside this category's cheaper quarter, which starts at $29. Premium is £40.83 for 20 sites.
- CFree plan and trialThe 41-check audit and its findings are free with no account, and a free account adds the fixes for 1 site. But its 3 AI-written files and 50 citation checks are one-time and never renew.
- CFeaturesThe audit, named AI crawler checks, an llms.txt generator, page-by-page crawls and daily re-audits. It does the readiness job fully, but that's a smaller job, and the citation check runs on one unnamed engine.
- BEase of useNo rating on record, but the audit runs from a URL with no account, and paid plans re-audit daily and email only when something changes.
- CPlatforms and integrationsWeb only, with no desktop or phone app and no integrations or API listed. Alerts come by email.

Keep it
Nothing llmstxt.studio does is plain enough to make in a weekend. The 2 things listed below take a company.
It is one of the better ones too: its GPA of 2.4 is higher than 125 of the 157 other AI search visibility tools we grade. It costs $251.13 a year.
What you could not
- A crawler that checks every page of a site.
- The same prompts asked of ChatGPT, Perplexity, Gemini and Google's AI answers every day, and the answers kept.
What this rests on. llmstxt.studio’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is llmstxt.studio?
llmstxt.studio runs a 41-check audit of how AI systems can reach, find, understand and quote a website, covering robots.txt rules for named AI crawlers, llms.txt, sitemaps, headings and structured data. A free account adds the fix for each finding and an llms.txt generator that writes the file from the sitemap. Paid plans re-audit daily, crawl pages in depth and run more AI citation checks.
Worth knowing
- Prices are shown in pounds by default, from the US too; the meta description says $19.90 a month but no dollar figure appears in the price data.
- The free account's 3 AI generations and 50 citation checks are one-time allowances that do not renew.
- The citation check runs against an AI search engine it does not name, so it is not a multi-engine tracker.
- The vendor says Google Search does not read llms.txt and that no major AI provider has confirmed using it.
Key features
- AI Readiness Audit
- 41 checks in five groups: whether AI crawlers can reach the site, find its key pages, understand the content, read structured data and quote it safely.
- Named AI crawler checks
- Reads robots.txt the way crawlers do and reports whether GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot and Google-Extended are allowed.
- llms.txt generator
- Writes an llms.txt from the sitemap, with AI-written page descriptions; a free account gets 3 AI generations and Pro has no limit.
- Deep Site Crawl
- Runs the 18 page-level checks on up to 100 pages a run on Pro or 500 on Premium, showing which pages fail which check.
- Audit monitoring
- Daily re-audits and sitemap checks on paid plans, emailing only when the score moves, a check flips or the llms.txt disappears.
- AI Citation Check
- Writes 8 queries from your llms.txt, runs them against an AI search engine and reports where you stand and which competitors were named.
