Summarize

Summarization Models

Summarize

The /summarize API takes a piece of text or fetches text from a given URL and generates grounded summaries that remain faithful to the original document (i.e. no external information is added during the process). The summaries are formatted as bullet lists, following the original text flow.

Summarize by Segment

The /summary-by-segment API takes a piece of text or fetches text from a given URL and breaks it into logical segments, returning summarized content for each segment, rather than one overall summary. This method is particularly useful for enabling users to read the original text faster and more efficiently. They can skim where possible and pay more attention where needed.

Text Segmentation

Features

Different types

In addition to working with free text, this API can also work directly with your favorite (or least favorite) webpage URLs! No need to spend time and effort scraping text yourself - just input the required URL and let the summarization begin.

Note: if the webpage you are trying to summarize is behind a paywall or restricted access, your call will fail and will result in an error.
