Similo: AI Related Posts

Description

Similo uses AI embeddings to find and display semantically related posts — articles that are actually about the same topic, even if they don’t share tags or categories.

Built for professional blogs with hundreds of posts: law firms, consultancies, academic publishers, and anyone whose readers deserve better content discovery.

How it works

  • When a post is published, Similo generates an AI embedding of its content
  • When a reader views a post, Similo compares embeddings to find the most similar articles
  • The most relevant posts are displayed as “Further Reading” at the bottom of each article

Why it’s different

Most related post plugins match by tags or categories. Similo understands meaning — so a post about GDPR enforcement and a post about data privacy fines will be connected, even if they were never tagged the same way.

Requirements

  • No API key needed — embeddings are handled via Similo’s external service.

External Services

This plugin sends post content to an external server to generate AI embeddings for related post detection.

FAQ

Which AI model does Similo use?

Similo uses OpenAI’s text-embedding-3-small — a fast, affordable embedding model.

Does it slow down my site?

No. Embeddings are generated once when a post is saved, not on every page load.

What similarity threshold does Similo use?

Posts with a cosine similarity score above 0.7 are shown. This keeps results relevant and avoids noise.

How many related posts are shown?

Up to 5 by default.

I just installed the plugin but no related posts appear.

Go to Tools Similo and click Generate All Embeddings to index your existing posts.
