How the Text Summarizer Works
This tool condenses any text into its most important sentences, which makes it ideal for quickly digesting articles, research papers, meeting notes or long emails. Paste your text, drag the slider to choose how much shorter the summary should be — for example 30% of the original sentences — and the summarizer instantly scores every sentence by how often its meaningful words appear across the whole text. The highest-scoring sentences are kept and re-ordered exactly as they appeared in the original, so the summary stays readable and faithful to the source. If you like, the first sentence is always kept because it usually contains the main topic. Everything runs locally in your browser: your text never leaves your device, there is no upload, no signup and no word limits.
