AI systems are answering questions about your business right now. When someone asks ChatGPT, Claude, Gemini, or Perplexity about your services, they either get it right or they guess. Most of the time, they guess wrong — confusing you with competitors, fabricating services you don’t offer, and recommending someone else entirely.
AI Discovery Files fix this. They are machine-readable files at the root of your website that tell AI systems exactly who you are, what you do, and how to refer to your brand. Think of them as <code>robots.txt</code> for AI — except instead of telling crawlers what to ignore, you tell AI systems what to get right.
This is the only WordPress plugin that generates all 10 AI Discovery Files defined in the <a href="https://www.ai-visibility.org.uk/specifications/" rel="nofollow ugc">AI Discovery Files Specification</a>.
<h4>Why your website needs AI Discovery Files</h4>
Without AI Discovery Files, your website is invisible to AI — not ranking poorly, completely absent from AI responses. With AI Discovery Files, you give every major AI system a single, authoritative source of truth about your business. You get mentioned. You get cited. You get recommended.
This is not traditional SEO. This is AI visibility — also called generative engine optimisation (GEO) or answer engine optimisation (AEO). Whatever you call it, it starts with AI Discovery Files.
<h4>All 10 AI Discovery Files</h4>
The <a href="https://www.ai-visibility.org.uk/specifications/" rel="nofollow ugc">AI Discovery Files Specification</a> defines 10 file types across three implementation tiers:
Essential (start here)
<ul>
<li><code>llms.txt</code> — AI-readable business identity (Markdown)</li>
<li><code>ai.txt</code> — AI usage permissions (plain text)</li>
</ul>
Recommended
<ul>
<li><code>identity.json</code> — Structured business identity (JSON)</li>
<li><code>ai.json</code> — Machine-parseable permissions (JSON)</li>
<li><code>brand.txt</code> — Brand naming and terminology rules</li>
<li><code>faq-ai.txt</code> — Pre-answered questions for AI systems</li>
</ul>
Complete
<ul>
<li><code>llm.txt</code> — Compatibility redirect to llms.txt</li>
<li><code>llms.html</code> — Human-readable reference version</li>
<li><code>developer-ai.txt</code> — Technical context for developers</li>
<li><code>robots-ai.txt</code> — AI crawler-specific directives</li>
</ul>
Most competing plugins only generate <code>llms.txt</code>. This plugin generates all 10 files, giving you complete coverage across ChatGPT, Claude, Gemini, Perplexity, Copilot, and every other major AI system.
<h4>How it works</h4>
<ol>
<li>Install and activate the plugin</li>
<li>Fill in your business details on the settings page</li>
<li>Choose which files to enable</li>
<li>The plugin serves the files at the correct root URLs (e.g., <code>yoursite.com/llms.txt</code>)</li>
</ol>
Files are generated dynamically from your settings — no files are written to disk, and everything updates automatically when you change your settings.
<h4>Key features</h4>
<ul>
<li>Auto-detection — pulls your site name, tagline, pages, theme, and WordPress version automatically</li>
<li>All 10 file types — the only plugin that generates every AI Discovery File, not just llms.txt</li>
<li>Three implementation tiers — start with Essential and expand when ready</li>
<li>Live preview — see exactly what each file contains before enabling it</li>
<li>Validation — checks files against the specification and flags issues</li>
<li>AI Crawler Analytics — see which AI bots read your AI Discovery Files, with visual dashboards and CSV export</li>
<li>Discovery File Access tracking — proof that AI bots are reading the files this plugin generates</li>
<li>robots.txt conflict detection — warns when your robots.txt contradicts your AI visibility settings</li>
<li>Conflict detection — warns if physical files already exist at the same URLs</li>
<li>Directory verification — verify domain ownership for the <a href="https://www.ai-visibility.org.uk/" rel="nofollow ugc">AI Visibility Directory</a> without FTP</li>
<li>No lock-in — disable the plugin and the files simply stop being served</li>
<li>Developer-friendly — filters for every generated file and collected data point</li>
</ul>
<h4>Who needs this?</h4>
Every WordPress site that wants to be found, mentioned, and correctly cited by AI systems. Local businesses, agencies, ecommerce stores, SaaS companies, professional services — if AI is answering questions about your industry, you need to control what it says about you.

LLM Friendly adds two capabilities to your WordPress site:
1) /llms.txt 
An LLM-friendly index of the website with main links and a list of latest items per post type. You can exclude individual entries from the feed via Settings → LLM Friendly → llms.txt → “Excluded items”.
2) Markdown exports 
For selected post types, the plugin exposes .md endpoints under: 
{base}/{post_type}/{path}.md 
Entries can override their Markdown body via the “Markdown override” sidebar panel (or Classic Editor metabox) and can also be excluded from export through the same settings page.
This is useful for LLMs, indexing bots, and users who prefer plain text. 
You can opt in to excerpts in llms.txt via <code>llms_show_excerpt</code>, and you can send <code>X-Robots-Tag: noindex, nofollow</code> for Markdown exports via <code>md_send_noindex</code> if you want Markdown-only consumers without search engine indexing. 
If the automatic Markdown conversion does not fit a post, use the “Markdown override” sidebar panel (Gutenberg) or the Classic Editor metabox to provide a custom Markdown or block-based replacement.
<h4>Key features</h4>
<ul>
<li>llms.txt endpoint with cached generation, optional excerpts, a configurable custom Markdown block, and a per-post exclusion list.</li>
<li>Markdown exports for selected post types with Gutenberg-to-Markdown conversion, per-post Markdown overrides (sidebar panel/metabox), and a per-post exclusion list shared with llms.txt.</li>
<li>Configurable base path for exports (e.g. “llm”) and per-post-type enable/disable toggles; changing the base path requires flushing rewrites.</li>
<li>Manual or automatic regeneration of the cached llms.txt with ETag/Last-Modified headers.</li>
<li>Optional X-Robots-Tag: noindex, nofollow for both /llms.txt and Markdown exports; the Markdown header is controlled by <code>md_send_noindex</code>.</li>
<li>Toggle excerpts in llms.txt via <code>llms_show_excerpt</code> to add one-line summaries under each item.</li>
<li>Optional site title/description overrides plus a sitemap URL field for the generated llms.txt.</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>WordPress 6.0+</li>
<li>PHP 7.4+</li>
</ul>
If requirements are not met, the plugin displays an admin notice and does not run.

LLM Friendly

Expose llms.txt and Markdown versions of posts/pages to make your site easier for LLMs to navigate and consume.
