Pan4 AI Visibility Toolkit

Is your website even found anymore – now that more and more people ask AI search systems instead of Google?

Pan4 AI Visibility Toolkit is the AI visibility toolkit for WordPress: score, live citation test, AI crawler tracking, and llms.txt generator – checks whether and how your content is found and cited by AI search systems (Google AI Overviews, ChatGPT, Perplexity). Completely free, no pro version, no hidden limits, no credit card required.

Why Pan4 AI Visibility Toolkit?

• Truly free. No free tier with an artificial cap, no “pro” version holding back the genuinely useful features.
• Score without an API key. The AI visibility score runs entirely on your own server – no account, no third-party access to your content needed to get started.
• A real test, not just a heuristic. The AI search actually asks a real AI search engine with web access, instead of just guessing.
• Privacy-friendly. AI crawler tracking detects bot visits purely from the user agent, without sending any data to an external service.
• No vendor lock-in. Settings import/export, the open llms.txt standard, works alongside any other SEO plugin.

AI Visibility Score

• On-page heuristic across 5 checks: direct-answer structure, heading/structure signals, E-E-A-T signals, paragraph independence, llms.txt
• 0–100 points per post/page, recalculated automatically on save
• Bulk recalculation for existing content, optional column in the post list
• Runs entirely locally, no API key needed

AI Search (live citation test)

• Queries a real AI search engine with live web access (Mistral, Perplexity, or OpenAI – your choice)
• Checks whether your own domain actually appears among the cited sources
• Runs only on manual click, never automatically in the background
• Requires its own API key (only for this one add-on feature; the score itself needs none)

Fully standalone

• No other SEO plugin required – has its own focus keyword field
• Own Gutenberg sidebar (block editor) and meta box (classic editor)
• Compatible alongside Yoast, RankMath, Seo-Pan & co.
• Settings import/export

External services

This plugin only contacts an external AI provider for the optional “AI Search” feature. This feature is disabled by default and only runs after you actively enable it, choose a provider, and enter your own API key for that provider. No other part of this plugin sends any data anywhere.

Each request is triggered exclusively by you manually clicking “Test live now” on an individual post or page – never automatically, never in the background, and never on a schedule. What is sent each time: a single short query text (your post’s focus keyword, or the post title if no focus keyword is set). Your own API key for your chosen provider is stored on your own server and is never sent to pan4.de or any other party.

You choose exactly one of the following three providers in the plugin’s dashboard:

Mistral AI (default option)
Used to ask whether a real AI search engine cites your website as a source for the query above.
Mistral AI: Terms of Service, Privacy Policy

Perplexity
Used the same way as Mistral, if you select Perplexity as your provider instead.

OpenAI
Used the same way as Mistral, if you select OpenAI as your provider instead.
