How does this AI summarizer work?

Extract-based summarization: Instead of generating new sentences, this tool scores every sentence in your text and picks the most informative ones, preserving the original wording and meaning.

Word-frequency scoring: Common stop words ("the", "and", "of") are filtered out. Each remaining word is counted, and every sentence is scored by the sum of its words' frequencies — sentences that mention the text's most important topics score higher.

Position bias: Opening and closing sentences of each paragraph carry a small bonus, mirroring how human readers weight introductions and conclusions.

Deduplication: A greedy algorithm selects the highest-scoring sentences while penalizing sentences that repeat information already chosen, keeping the summary diverse and compact.
