Kagi says its name comes from the Japanese word meaning “key.”
The word is 鍵, romanized as kagi, and it literally refers to a key. The name suits a search service designed to help people unlock information on the web. Kagi is a paid search engine developed by Kagi Inc. and is known for operating without advertising or sponsored search results.
Kagi’s business model is an important part of its identity. Rather than relying primarily on advertisers, it charges users through subscription plans. That approach is intended to reduce incentives to shape results around advertising revenue and gives users tools such as website blocking, lenses, and customizable search preferences.
A common mix-up is to treat “kagi” as an English technical acronym or as a reference to a physical gate. It is neither: the name comes from Japanese, where 鍵 means “key.” The company’s name and branding therefore express the idea of opening access to useful search results, not a signal or mirror.
