## 説明

**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. Activate the plugin and it just works,
free for the first 25 summaries 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:** when you click “Generate summary” (or, with auto-summarise
   on, when you
    publish a post), the plugin sends the **post title** and **post
   content** to the API. A non-identifying **site ID** (a hash of your site URL)
   is sent for usage counting.
 * **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.

## FAQ

### Do I need an AI API key?

No. The AI runs on our service.

### Where does the summary appear?

Wherever you place the `[altosum]` shortcode, or automatically at the top/bottom
of single posts if you enable that.

### Does it send my content anywhere?

Only when you generate a summary, and only the title and content. See the External
Services section.
