Free web demo · LLM readiness check

Free AI visibility check for websites.

Check for free how well your website is already prepared for AI crawlers, llms.txt, AI search, ChatGPT-style systems and later LLM mentions. The web demo measures online-available signals immediately; the full version adds real model, market and competitor data.

The free version measures server-side online-available signals such as reachability, robots.txt, sitemap, llms.txt, title, meta, H1, visible text, JSON-LD, legal notice, privacy and a small mini crawl.

Checking website live …
Important: the free web demo does not run large paid multi-LLM checks for arbitrary third-party websites. That is what the premium version is for. However, the free version already shows very clearly whether the technical and semantic foundations for later AI visibility are present.

What the demo can already measure live

This free web version is not just a blind form. It already checks multiple technical and LLM-related signals live against the entered URL – server-side, quickly, and without requiring the user to provide API keys.

  • Reachability, HTTPS, redirects and rough load time
  • robots.txt, sitemap, llms.txt and AI crawler hints
  • title, meta description, H1, visible HTML text and mini crawl
  • structured data, entity signals, legal notice, privacy and encoding

What the full version adds

The professional version goes much deeper: real multi-LLM queries, deeper SERP and news analysis, competitor comparison, local model fleets, weights probing, exports, action catalogues and ongoing monitoring.

  • Real multi-LLM tests with cloud and local models
  • SERP, news and competitor analysis
  • JSON, CSV and DOCX exports
  • Action plan, priorities and monitoring

All modules of the AI visibility check

Every module has its own page with a clear explanation, LLM/AI context, demo notes and a clear premium outlook. This helps users quickly find the area that matters most for their website.
