Liner

Liner is an AI search engine built for students, researchers, and knowledge workers who need answers they can trust. Founded in 2012 as a web highlighter and rebuilt around large language models after GPT-3, the company now serves roughly 12 million monthly users across more than 200 countries, pairing conversational answers with transparent citations from academic papers and vetted sources. Headquartered in San Francisco with roots in Seoul, Liner positions itself as a source-grounded alternative to general chatbots and to Google's search box.
