Frequently asked questions
How does extractive summarisation work?+
It selects and keeps the most important existing sentences rather than writing new ones, so the summary stays factually close to the source.
Will it change my wording?+
No. It reuses your sentences verbatim, so the summary uses your exact phrasing.
How long should my input be?+
It works best on 3+ paragraphs. Very short text has too few sentences to rank meaningfully.
Is my text uploaded?+
No. Summarisation happens entirely in the browser.
