Glossary
Answer engine
An answer engine responds to a query with a composed answer rather than a list of links, drawing on retrieved sources and usually citing some of them. ChatGPT, Perplexity, and Google's AI Overviews and AI Mode are the prominent examples.
The distinction from a search engine is architectural: a search engine ranks documents and hands the reader a choice; an answer engine reads the documents and hands the reader a conclusion. The line blurs in practice — the major search engines now embed answer layers directly in their results, and the standalone assistants increasingly search the live web before answering.
For anyone who publishes on the web, the change is economic before it is technical. Visibility in a ranked list produced clicks; visibility in a composed answer produces citations, brand mentions, and — disputed, and centrally so — some fraction of the clicks it replaced.
The wire covers answer engines as its core beat: what they ship, what they cite, and what they change.
Common questions
What is an answer engine?
A system that responds to a query with a composed answer instead of a list of links, drawing on retrieved sources and usually citing some of them. ChatGPT, Perplexity, and Google's AI Overviews and AI Mode are the prominent examples.
What is the difference between an answer engine and a search engine?
A search engine ranks documents and lets the reader choose; an answer engine reads the documents and hands the reader a conclusion. The line blurs in practice, because search engines now embed answer layers in their results and standalone assistants increasingly search the live web before answering.
Why do answer engines matter to publishers?
Because they change what visibility pays. A place in a ranked list produced clicks; a place in a composed answer produces citations and brand mentions, plus some disputed fraction of the clicks it replaced.
