HyperWrite grew from a GPT-3 email trick into a writing desk, research aide and browser operator. Its signature feature is still the least theatrical one: a useful next sentence, waiting where you already type.
Give Claude the Whole Assignment
Claude has grown from a careful chatbot into a workbench for writing, research, code and files. It rewards people who bring context, judgment and a job worth finishing - but its shifting usage limits still demand a little housekeeping.
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.
Consensus
Consensus is an AI-powered academic search engine that lets anyone ask a research question in plain language and get answers drawn directly from peer-reviewed science. Instead of returning a list of blue links, it reads across more than 200 million papers, summarizes findings, and shows - via its signature Consensus Meter - how much the published literature agrees. Founded in 2021 by Eric Olson and Christian Salem, the company is building what it calls an AI operating system for researchers, used by millions of students, scientists, clinicians and curious people.
