Juanjo Labs Semantic Related Posts

Description

Juanjo Labs Semantic Related Posts shows related articles using real semantic similarity (AI embeddings), not just shared tags or categories like most related-posts plugins.

Why does this matter? A traditional related-posts plugin only compares shared tags and categories. This plugin understands what each article is actually about and finds genuinely similar content, even if it doesn’t share a single tag.

4 matching modes, not just AI

Pick whichever mode fits your site best — all four are available in both Lite and Pro:

• AI semantic — embeddings, finds real similarity of meaning
• By category — most recent posts from the same category
• By tags — posts sharing the most tags with the current one
• Hybrid — combines tags + category, with AI re-ranking if an API key is configured

Lite version features (free)

• All 4 matching modes (AI, category, tags, hybrid)
• Embeddings generated from each post’s title and excerpt (AI mode)
• Unlimited posts indexed with AI
• Choose which public post types are included (posts, pages, WooCommerce products, other custom post types) — with automatic price display for products
• 1 widget style (simple grid)
• Manual embeddings recalculation
• Basic SEO metadata for Rank Math (title, description and ALT generated by rules, no API cost)

With the Pro version you get

• Embeddings over the full post content (higher accuracy in AI mode)
• Automatic recalculation via cron (Lite is manual, on demand)
• 3 widget styles (Grid, List, Compact) and a customizable accent color
• Dedicated WooCommerce integration hook for classic themes where the product page doesn’t run the_content (covers cases the standard content filter misses)
• Manual post exclusion and per-category weight control
• SEO metadata generated with real AI (Claude) for Rank Math: title, description and image ALT text
• Priority email support

Upgrade to Pro anytime from the plugin’s settings page in your WordPress admin (Settings → Semantic Related Posts → Licencia).

Use cases

• Blogs and news sites that want to reduce bounce rate
• E-commerce sites with products related by real description, not just category
• Multilingual sites that need an alternative to English-only plugins

External services

This plugin connects to third-party AI APIs to provide its core features. You must supply your own API key for each service you want to use; the plugin never sends data to these services without a key configured, and none of your API keys are ever sent to us (Juanjo Labs) or to any server other than the provider’s own.

Voyage AI (embeddings) — used to generate the semantic embeddings that power the “AI semantic” and “Hybrid” related-posts modes.
It sends the title and excerpt of each published post (and, in the Pro version, the full post content) to Voyage AI’s API whenever a post is created or updated and an API key is configured. No data is sent if this mode isn’t in use or no API key is set.

Anthropic API (Claude) — used only in the Pro version, to generate SEO metadata (title, description, focus keyword) and image ALT text for Rank Math.
It sends the post’s title and content (for metadata) or an image’s binary data (for ALT text) to Anthropic’s API when you use the “Generate SEO” tools and an Anthropic API key is configured. No data is sent if no API key is set, or in the Lite version, which generates this metadata locally using simple rules instead.
