AltoSum – AI Post Summary, TL;DR & Key Takeaways

No API key. No account. No setup. Unlike almost every other AI summary plugin, which makes you sign up for OpenAI or Anthropic and paste in your own paid API key, AltoSum runs the AI on our hosted service, so there is nothing to configure. You generate each summary with one click from the post editor, free for the first 25 every month.

AltoSum reads your post and writes a short TL;DR plus a few key-takeaway bullets, then shows them in a tidy box at the top (or bottom) of the article. Great for readers in a hurry and for the AI search engines that increasingly quote summaries.

The free plan covers 25 summaries per month; AltoSum Pro removes the monthly limit (subject to fair use) and can summarise automatically on publish.

• No API key or third-party account. The AI runs on our service.
• One click to generate a summary from the post editor.
• Show it via the [altosum] shortcode, or auto-insert it into single posts.
• Optional key-takeaway bullets.
• Privacy-friendly: automation is off until you switch it on, and only the post title and content (plus a non-identifying, hashed site ID) are ever sent.
• Pro: unlimited summaries (subject to fair use) and auto-summarise when you publish.

External services

This plugin connects to the Really Useful App Company API to generate summaries. It is required
for the plugin’s core feature.

• What is sent and when: the plugin sends the post title and post content to the API on
  each of these actions, and nothing else triggers a send:
  • when you click “Generate summary” in the editor
  • when you publish a post with auto-summarise on
• Also sent: a non-identifying site ID (a hash of your site URL) for usage counting, and the
  plugin version, so we can tell which release a report relates to. Neither identifies you. Whether this site’s review prompt was shown, snoozed, dismissed or clicked is also sent, so we can tell whether that prompt is working. It records the site, not the individual user, and says nothing about what you did on WordPress.org afterwards.
• Where it goes: the API (default https://api.thereallyusefulappcompany.com), which uses Anthropic as an AI
  subprocessor to generate the text.
• Terms / privacy: https://www.thereallyusefulappcompany.com/altosum/terms , https://www.thereallyusefulappcompany.com/altosum/privacy ,
  https://www.anthropic.com/legal/privacy

No data is sent until you click generate or publish with auto-summarise enabled.
