Limitations and notes

  • It is an extractive summary, not artificial intelligence: it scores each sentence by the frequent words of the text itself and rewrites nothing.
  • It works best on articles and informative text; on dialogue, poems or lists it may pick sentences that are not very representative.
  • The text never leaves your browser.

Frequently asked questions

Why does it copy sentences instead of writing a summary?

So nothing is invented: every sentence in the summary exists in your text. Rewording would need an AI model, which this tool does not use.
