Summarizer offers two summarization types: extractive and abstractive.

An extractive summary is based on a percentage of the original text length. The percentage can be as low as 5% and as high as 90%. If you choose to view a preview of your extractive summary, you can adjust the percentage in real-time before finalizing the summary and emailing or printing the result.

An abstractive summary is a short and concise interpretation of the source text, generated using artificial intelligence. Abstractive summaries can potentially contain new phrases and sentences that may not appear in the original source text.

Note: Extractive summaries use 1 credit per page while abstractive summaries use 2 credits per page.
