Frequently Asked Questions
How does this summarizer work?
This tool uses extractive summarization. It analyzes word frequency across all sentences, scores each sentence by the importance of its words, and extracts the top-ranked sentences to form a coherent summary.
Does this tool use AI or API calls?
No external API calls are made. The summarization algorithm runs entirely in your browser using client-side JavaScript. Your text is never sent to any server.
What kind of text works best?
This tool works best with informational or expository text such as articles, essays, reports, and research papers. It is less effective with poetry, dialogue, or very short texts.
How many sentences are included in the summary?
The number of summary sentences scales with the length of your input. Short texts get 1-2 sentences, medium texts get 3-4, and long texts get up to 5-7 key sentences.
