In an era flooded with AI services, finding reliable information has only become harder. Liner has spent the past decade obsessing over a single problem: search without hallucinations. The company says it has achieved that through a proprietary retrieval-augmented generation (RAG) stack that processes 460 million academic records in real time. Now, it’s positioning itself beyond AI search—toward a full-fledged agent platform aimed at transforming knowledge work. In a recent interview, CEO Luke Kim outlined the company’s strategy and what comes next.
