Free. No account, no tracking. Works on any http(s) site.
Four checks, one click

What it audits.

Every check that determines whether an LLM can find, understand, and cite your site. All four run in parallel from a single popup.

/llms.txt

llms.txt status and quality

Confirms the file exists, fetches it cleanly, and grades the structure.

  • HTTP status, file size, content type, last-modified date
  • H1, H2, H3, link, and word counts
  • Soft-404 detection (HTML returned in place of a real file)
  • 4KB content preview, one-click view, copy URL
/llms-full.txt

llms-full.txt expanded version

Same depth of analysis for the expanded full-content file that many LLMs prefer for context.

  • All the metrics from llms.txt
  • Side by side, so you can see if both files are deployed
  • Quality comparison at a glance
robots.txt

AI crawler access

Parses robots.txt and shows allowed, blocked, partial, or default status for the ten AI crawlers that matter.

  • OpenAI: GPTBot, ChatGPT-User, OAI-SearchBot
  • Anthropic: ClaudeBot, Claude-Web
  • Google: Google-Extended (Gemini training)
  • Plus PerplexityBot, Applebot-Extended, Bytespider, CCBot
meta tags

Page-level AI signals

Scans the page head for AI opt-out signals and bot-specific meta tags that override robots.txt at the page level.

  • noai and noimageai content directives
  • Bot-specific meta names (GPTBot, ClaudeBot, etc.)
  • Surfaces conflicts between robots.txt and meta policy
Setup takes ten seconds

FAQ

Common questions.

Is it free?

Yes. The extension is free, with no account required and no usage limits. We built it as a free tool for the GEO and SEO community. If you want deeper audits, citation tracking, and ongoing visibility monitoring, that is what amivisible.co offers as a paid product.

What data does the extension collect?

None. The extension does not collect, store, transmit, sell, or share any data. No analytics, no tracking pixels, no third-party SDKs. All checks happen locally in your browser, talking directly to the site you are on.

Full details on the privacy policy page.

Why does it ask for access to all websites?

The extension needs to fetch llms.txt, robots.txt, and the current page HTML from whatever site you are viewing. That requires the "Read and change all your data on all websites" permission in Chrome. We do not read anything beyond those files, and we do not transmit anything anywhere. The source is auditable.

What is llms.txt?

llms.txt is a community proposal for sites to publish an LLM-friendly markdown summary at /llms.txt. Think of it as robots.txt for content discoverability by language models. The expanded version, llms-full.txt, includes the full content rather than just an index.

See llmstxt.org for the full spec.

Does blocking an AI bot in robots.txt actually work?

Reputable AI crawlers (GPTBot, ClaudeBot, Google-Extended, PerplexityBot, Applebot-Extended) respect robots.txt directives. Some less reputable crawlers do not. Robots.txt is the right first lever to pull, and the extension shows you exactly which AI vendors you are currently allowing or blocking.
