Frequently Asked Questions
How does extractive text summarization work?
It scores each sentence using term frequency-inverse weighting and structural position (such as intro and conclusion emphasis) to select the most informative, representative sentences without distorting factual meaning.
Can I summarize confidential or proprietary text safely?
Yes! 100% of the extraction algorithm runs strictly within your browser's local memory. No text is ever uploaded or saved.
