Text Summarizer
Summarize long text by extracting the most representative sentences.
What is Summarize?
An extractive summarizer: it scores sentences by content-word frequency and picks the most representative ones, in their original order.
How it works
Each sentence is scored by how many high-frequency content words it contains (normalized by length), then the top N are returned in document order.

Common mistakes
Extractive vs abstractive summaries
This tool extracts key original sentences rather than generating new prose, so it preserves facts but not a rewritten narrative.
Frequently asked questions
How does it pick the key sentences?
It scores sentences by term frequency and position, then selects the highest-scoring ones until the target length is reached.
Can I control the length?
Yes — set a percentage or target sentence count.
