In AI, summarization produces a shorter version of text or other information so a person can understand the main points more quickly. A system may select key passages or write a new account based on the source.
A good summary remains faithful to the material it condenses and makes important context easy to verify. It can still omit a qualification or repeat an error in the source, so consequential details should be checked against the original information.

Summarization means making a shorter account of a longer piece of information. The goal is to keep the main ideas without making someone read every detail first.
For example, an AI assistant might condense several neighborhood posts about a street closure into a few sentences about where and when it is reported. A reader should still be able to open the posts to check the details.
