Publish a blog post. Get a precise, AI-generated summary — automatically, in the background, with zero extra effort.
AI Blog Summariser is a lightweight WordPress plugin that uses the Anthropic Claude API to generate concise summaries of blog posts the moment you hit “Publish.” The summary is stored as a custom meta field and can be displayed anywhere in your theme — via shortcode, Elementor, or plain PHP.
The plugin is developed by Nettsmed and used in production on nettsmed.no.

How It Works
- Install the plugin and enter your Anthropic API key under Settings → AI Summariser
- Publish a post as usual — the plugin triggers automatically in the background
- The summary is saved to the post’s meta field and ready to use in your theme, Elementor, or any page builder
Saving the post takes no longer than usual. The summary appears within seconds after publishing via a background job (WP-Cron).
