How to use the Text Summarizer
Paste any article, blog post, essay, or document into the text box, or use the Paste button to pull text from your clipboard
Choose Short, Medium, or Long to control roughly what percentage of the original sentences are kept in the summary
Select Custom to set an exact percentage of sentences to retain, anywhere from 5 to 90 percent
Click Summarize to run the TF-IDF scoring engine and extract the most important sentences from your text
The summary is extractive, meaning every sentence shown is taken directly from your original text rather than rewritten
Sentences are scored using term frequency and inverse sentence frequency, so words that are distinctive to the document score higher
Opening and closing sentences receive a small scoring boost since they often carry the most important context
Very short sentences and unusually long sentences are slightly down weighted to favor clear, well formed statements
Use the Top Keywords list to quickly see which terms carried the most weight in the scoring engine
Switch between All Sentences, In Summary, and Excluded in the Sentence Breakdown table to inspect exactly what was kept
The relevance bar for each sentence shows its normalized score, with the highest scoring sentences in the summary shown in blue
Use Copy Summary to grab the generated summary text and paste it directly into your blog editor or notes
For best results, paste at least a few paragraphs of well structured text, since the scoring engine relies on having enough sentences to compare against each other
All processing happens entirely in your browser, so your text is never uploaded or sent to a server
