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. 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.
