Frequently asked questions

How does the summarizer work?

It's an extractive summarizer: it scores every sentence by how many of the text's most important words it contains, then picks the top sentences and keeps them in their original order.

Does it rewrite the text?

No. The summary uses your original sentences, so it never invents facts — every point comes straight from the source.

Is my text private?

Yes. Summarizing runs entirely in your browser; nothing is sent to a server or an AI service.
