Frequently asked questions
How does it decide which sentences to keep?
It uses extractive summarization: each sentence is scored by keyword frequency and position. The highest-scoring sentences are kept up to your chosen count.
Can it summarise long documents?
Yes — there's no length limit beyond your device's memory. Paste entire articles or chapters.
Is this AI?
It's a deterministic scoring algorithm, not a generative AI model. That makes it instant, private, and predictable — the same input always gives the same summary.
Is my text uploaded?
No — summarization runs entirely in your browser.
