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.
