Extract key points and shorten long text instantly
Summary:
This tool uses extractive summarization — it identifies and extracts the most important sentences from your text without rewriting them. The algorithm scores each sentence based on word frequency (words that appear often across the text are weighted higher), sentence position (first and last sentences of paragraphs carry more weight), and sentence length (very short or very long sentences are penalized). The top-scoring sentences are returned in their original order.
Extractive (this tool) — selects existing sentences directly from the source. Output is always factually accurate because nothing is rewritten. Best for: legal documents, technical articles, news, academic papers.
Abstractive (used by ChatGPT, Claude) — generates new sentences that paraphrase and condense the content. Can synthesize across paragraphs but may introduce inaccuracies. Best for: casual summaries, meeting notes, creative content.
Paste at least 200 words of text (shorter text produces poor summaries). Choose compression level: 25% returns about a quarter of sentences, 50% returns half. Click Summarize. The output is suitable for skimming, notes, or a starting point for your own rewrite. For best results, use clean plain text without bullet points or tables.
This tool cannot understand context, detect irony, or synthesize conclusions. If the source text is poorly structured, the summary will be too. For AI-powered abstractive summaries, use a language model directly.
