Features
Kagi
Kagi functions as a metasearch engine to aggregate search results from other established search engines with its own indexes for websites and news. They run their own crawler under the brand name Teclis, although this index is only used for small-web searches. In 2024, Kagi stopped listing specific traditional search engines included in their sources; before this, these sources included Google, Brave Search, Mojeek and Yandex.The search engine enables results to be filtered by category with a feature called lenses and enables the user to create their own lenses. Available lenses include filtering to find discussions, podcasts, search directly for PDF files, and filtering to focus content from smaller websites like blogs and forums. Websites shown in search results can be upvoted, downvoted, and blocked. Shortcuts called bangs can be created which allow searches to be redirected to different websites. There is also an AI quick response feature that summarizes a search query and gives sources. Details about websites can be shown in the search results such as creation date and counts of ads and trackers. Kagi also allows for customization of the user interface with a custom CSS editor.
