RK Smart Internal Linker analyzes your content in real time and suggests the most relevant internal posts to link to — right inside the Gutenberg sidebar. No external APIs, no monthly fees, no data leaving your server.
How it works:
<ol>
<li>On activation, the plugin creates a keyword index table and begins indexing your published posts via WP-Cron (20 posts every 5 minutes).</li>
<li>When you open a post in the editor, the plugin extracts the top keywords and scores every other post by keyword overlap (TF-IDF).</li>
<li>The top 5 results appear in a sidebar panel with Copy Link and Insert Link buttons.</li>
</ol>
Features:
<ul>
<li>100% local — no API keys, no external calls</li>
<li>TF-IDF keyword scoring for smart relevance</li>
<li>Background indexing via WP-Cron (server-friendly batches)</li>
<li>Instant re-index on post save</li>
<li>Clean Gutenberg sidebar with score badges</li>
<li>One-click copy or insert links</li>
</ul>
