About the project

A short trail back to the original.

Summarization.org is a reading aid for people who need to inspect long English text without losing their place in it.

The tool has two modes. Passage mode selects existing sentences and gives each one a source position. AI mode writes summary points, each labelled fact, opinion, or inference, and each carrying a quote that must be found exactly once in the text you supplied; points that fail that check are removed rather than shown. The tool does not claim to verify a source, judge whether a claim is true, or rank authors.

The tool is free. We have no accounts, subscription, affiliate links, testimonials, or invented usage figures on this site. The method and data boundary are published so you can decide whether it fits your work.

For third-party claims in editorial guides, see sources. For any summary point, the most important source is the text you supplied: click the point and read the quoted words in context.
