Every sentence gets a relevance score. Pin a sentence to force it into the summary, or exclude it. The final order always follows the source.
Keywords are extracted locally from the source and help explain why sentences rank highly. They are not external search terms.
Compare short, balanced and detailed summaries side by side without rerunning the document.
History is session-only unless browser saving is enabled on the right. Nothing is synced to a server.
Method: OneFreePlace #431 uses local sentence extraction, language-aware tokenization, frequency signals, focus-term boosts, section/position signals and redundancy penalties. It does not claim AI semantic generation. The advantage is privacy and source traceability; the trade-off is that highly abstractive summaries may require a real language model.
