This tool uses extractive summarization. It analyzes sentences based on word frequency, position in the text, and presence of key indicator words, then selects the most important sentences while preserving their original order. ### What's the difference between extractive and abstractive summarization? Extractive summarization selects and combines existing sentences from the text. Abstractive summarization (used by AI models like GPT) generates new sentences that paraphrase the content. This tool uses extractive summarization, which guarantees that every sentence in the output appears word-for-word in the original. ### What type of text works best? Well-structured texts with clear sentences work best: articles, research papers, reports, essays, and news stories. Texts with bullet points, lists, or fragmented sentences may not summarize as effectively because the algorithm relies on complete sentence structure. ### How accurate is the summary? The summary extracts statistically important sentences based on word patterns and positional weighting. For critical applications like academic citations or legal briefs, always review the summary against the original text to ensure all key points are captured. ### Is my text stored or sent anywhere? No. All processing happens directly in your browser using JavaScript. Your text never leaves your device and is not stored, logged, or sent to any server. This makes it safe for confidential and sensitive documents. ### Does this text summarizer require a signup? No. This tool is available with no sign-up, no word limits, and no usage caps. You can summarize as many texts as you need without creating an account or paying for a subscription. ### Can I summarize a PDF or Word document directly? The tool accepts plain text input only. To summarize a PDF or Word document, copy the text content from the file and paste it into the input field. For PDFs, you can use a PDF-to-text extractor first. ### How do I choose the right summary length? Use Short (20%) for a quick overview or executive summary, Medium (40%) for a balanced summary that retains most key points, and Long (60%) when you need thorough coverage with only minor details removed. You can also set a custom percentage with the slider. ### Does the summarizer work with languages other than English? The algorithm analyzes word frequency patterns, which works across most Latin-alphabet languages. Results are best for English text, but you can get reasonable summaries for French, Spanish, German, and other European languages. ### What is the maximum text length I can summarize? Since all processing happens in your browser, there is no server-imposed limit. The practical limit depends on your device's memory. Most modern browsers handle texts up to 100,000 words without issues. ## Related Tools - [Word Counter](https://findutils.com/text/word-counter/) - [Reading Time Estimator](https://findutils.com/text/reading-time-estimator/) - [Readability Calculator](https://findutils.com/text/readability-calculator/) - [Character Counter](https://findutils.com/text/character-counter/) - [Tone Analyzer](https://findutils.com/text/tone-analyzer/) - [Case Converter](https://findutils.com/text/case-converter/) - [Text Line Sorter](https://findutils.com/text/text-line-sorter/) - [Duplicate Line Remover](https://findutils.com/text/duplicate-line-remover/)
