About the Text Summariser
This text summarizer reduces a document to its most representative sentences using extractive summarisation. Every sentence in the output appears verbatim in your source, so nothing is paraphrased or invented.
A text summarizer that works extractively scores each sentence by how representative it is — largely by the significant terms it contains and how central those are to the document — then returns the highest ranked ones in their original order.
The distinction from generative summarising is the whole point. A language model rewrites, and in rewriting can introduce claims the source never made. Extractive summarisation cannot, because every output sentence is copied verbatim. When the summary will be read as though it were the document, that guarantee matters more than elegance.
The trade-off is smoothness. Extracted sentences do not always flow together, and a pronoun in a selected sentence may refer to something in a sentence that was not selected. It works best on structured prose — reports, articles, papers — and poorly on dialogue or narrative.

Frequently asked questions
Does it use AI to rewrite my text?
No. It selects existing sentences verbatim. Nothing is paraphrased, and nothing can be invented.
Why prefer extractive over generative summarising?
Because a rewrite can introduce claims the source never made. Extracted sentences cannot.
What kind of text works best?
Structured prose — reports, articles and papers. Dialogue and narrative summarise poorly.
Why does the summary read a little disjointed?
Extracted sentences were written to sit in context. A pronoun may refer to a sentence that was not selected.
Is my text uploaded?
No. Summarisation happens entirely in your browser.
