Summarize long text online free using extractive summarization. The algorithm scores sentences by word frequency and selects the highest-scoring original sentences in their original order. Adjust the summary length from 10% to 80% of the source text, then copy the result. Works best with articles, blog posts, meeting notes, research excerpts, reports, and structured long-form text. Processing happens in your browser, so your text is not uploaded by this tool.
Reading long articles takes time. A good summary lets you quickly grasp the key points and decide if the full text is worth reading. Researchers use summaries to quickly scan papers for relevance. Students use them to review study materials efficiently. Content curators use them to understand articles before sharing. Business professionals use them to quickly digest reports and documents. This tool makes summarization instant and accessible without AI API costs.
This tool uses extractive summarization — it selects the most important sentences from the original text without rewriting them. This preserves the original wording and is more reliable than abstractive summarization. Abstractive summarization (like ChatGPT) rewrites content in new words, which can introduce errors or change meaning. For factual content like news articles and research papers, extractive summarization is often preferred.
Extractive summarization works well when the original text has clear sentences, repeated themes, and informative topic words. Articles, documentation, meeting notes, reports, and research abstracts usually produce better summaries than poetry, bullet-only notes, chats, or very short text. For nuanced rewriting or tone changes, use a human editor or an abstractive AI workflow.
After generating a summary, read it for missing context, pronouns without references, and sentences that depend on removed paragraphs. If it feels too short, increase the summary length. If it feels repetitive, lower the percentage or edit manually. For important documents, treat the summary as a draft and verify it against the original.
