Web Page Summary (AI)

Summarize any web page: send a URL, get a factual summary that starts with what the page is, followed by the key facts, numbers and conclusions as bullet points. Reads the page (HTML to Markdown) and summarizes it with Claude Haiku 5.5. Options: length short (60 to 90 words), medium (150 to 220) or long (350 to 450); language for the summary (default: the page language, e.g. German); focus to steer it (e.g. "pricing and plans"). Page content is treated as data, instructions inside the page are ignored. Long pages are cut at about 25,000 characters (input_truncated says so). Not charged when the page cannot be read.
