About Text Summarizer
The average knowledge worker spends 2.5 hours per day reading emails, articles, and reports. A reliable text summarizer cuts that time by surfacing the sentences that carry the most meaning. Our Text Summarizer uses extractive summarization: it scores every sentence based on how frequently its important words appear across the entire text, then returns the top sentences in their original order. This is not generative AI, so it will never hallucinate or invent facts—it only pulls from what you provide. You can request anywhere from 1 to 10 sentences, making it useful for everything from quick abstracts of 500-word blog posts to condensed versions of 5,000-word white papers. Use it to preview long documents, prepare meeting notes, or generate metadata snippets without losing the author's original intent.
How It Works
The tool first splits your input into sentences using punctuation-based regex. It then builds a frequency table of meaningful words, ignoring a standard list of stop words such as 'the,' 'and,' and 'is.' Each sentence receives a score equal to the sum of its important word frequencies. The highest-scoring sentences are selected, then re-sorted by their original position so the summary remains coherent and chronological.
Formula & Calculation Logic
For each sentence S, score(S) = sum(frequency(w)) for every non-stop word w in S. Stop words are filtered out, and only words longer than two characters are counted. The sentences with the highest scores are returned, preserving original order. The assumption is that words appearing more often are more central to the topic, which holds true for well-focused content but may miss nuanced arguments.
