LINER AI is a research productivity tool that combines web highlighting, content saving, and AI-assisted search into a single platform. Users can highlight text on any webpage or PDF, save it to a personal library, and retrieve it later. The AI layer allows users to ask questions and receive answers grounded in cited sources, reducing the need to sift through multiple search results manually. LINER operates as a browser extension and a web application, making it accessible across different workflows. It is designed to support students, researchers, and knowledge workers who regularly consume large volumes of online content. The product emphasizes source transparency by linking AI-generated responses back to the original documents or pages, helping users verify information. LINER also surfaces relevant content recommendations based on saved highlights, supporting ongoing research projects. The tool is positioned as an alternative to traditional bookmarking and note-taking apps, with an added AI search layer built on top of curated personal and web-wide content.
