Text summarization is the process of creating a concise and coherent version of a longer document while preserving its key information and meaning. This tool uses extractive summarization, which identifies and extracts the most important sentences from the original text.
The TF-IDF (Term Frequency-Inverse Document Frequency) algorithm used here is a proven technique in natural language processing. Research published in the ACL Anthology shows that TF-IDF-based summarization achieves comparable results to more complex models for many practical use cases, while being significantly faster and more transparent.

The summarizer uses TF-IDF (Term Frequency-Inverse Document Frequency) scoring to identify the most important sentences in your text. It tokenizes sentences, calculates word frequencies while filtering common stopwords, and scores each sentence by the sum of its word frequencies. The top-scoring sentences are returned in their original order.
What is extractive summarization?
Extractive summarization selects the most important sentences from the original text without modifying them. Unlike abstractive summarization (which generates new text), extractive methods preserve the exact wording while condensing the content to its most essential points.
What summary lengths are available?
You can choose from 3, 5, or 10 sentences for your summary. Shorter summaries (3 sentences) focus on the absolute most important points, while longer summaries (10 sentences) provide more context and detail.
Is my text data private?
Yes, absolutely. All summarization happens directly in your browser using JavaScript. Your text is never sent to any server or stored anywhere. This tool works entirely offline once the page is loaded.
Does it work with non-English text?
Yes, the summarizer works with any language. The TF-IDF algorithm identifies important words based on their frequency relative to the document, so it doesn't rely on language-specific processing.
