LightSite AI vs llmstxt.studio (2026): which should you pick?

Pick LightSite AI if

• Fits if you want structured data and an AI sitemap added to your site through one snippet
• Works for large brands tracking AI answers in Japan or other local languages, on Enterprise

Look elsewhere if

• Pricey if you just want AI answer tracking, as daily checks with competitors and citations start at $299 a month
• Tight if more than one person or domain is involved, as Foundation and Pro cover 1 user and 1 domain
• Skip it if you'd rather pay monthly, as every plan is billed a year upfront
• Watch out: the 7-day trial turns into a paid year unless you cancel it
• Watch out: Search Console, content drafts and implementation support are Enterprise only

Pick llmstxt.studio if

• 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

Look elsewhere if

• 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

LightSite AI

• Plans are billed annually in advance; no monthly option is shown on the pricing page.
• Foundation and Pro cover one user and one domain; more users and domains need Enterprise.
• The trial converts to a paid year unless cancelled; a pro rata refund is possible in the first 90 days.
• Google Search Console, content drafts and implementation support are Enterprise only.

llmstxt.studio

• 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.

LightSite AI

AI-readable website layer

A snippet or tag manager install publishes structured endpoints, JSON-LD, an AI sitemap and agent manifests on your domain, with no CMS plugin.

AI bot and crawler analytics

Records which AI crawlers and agents request which pages; Pro adds bot journey, page-level and link-level analytics.

AI search visibility tracking

Pro tracks prompts daily across ChatGPT, Gemini, Claude and Perplexity, with competitor, sentiment, position and citation source analysis.

LLM traffic attribution

On Pro, counts human visits referred by AI assistants where the referral can be identified.

Action recommendations

Pro suggests fixes to improve how the brand appears; Enterprise adds content briefs and drafts, gap scans and outreach preparation.

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.
