LINER AI

LINER AI: Smart Search Assistant & Digital Highlighter

LINER AI supercharges your Google searches with trustworthy, AI-curated answers while doubling as a digital highlighter for saving and sharing content.

Overview

LINER AI transforms the way you research and learn online by combining AI-powered search enhancement with digital annotation tools. Built on ChatGPT and a proprietary semi-parametric model, LINER injects your Google searches with References and Search Next features, surfacing answers grounded in credible sources rather than generic web results. It essentially filters the internet through the collective judgment of millions of engaged users, helping you cut through noise and land on trustworthy information faster. Beyond search, LINER doubles as a universal digital highlighter that works seamlessly across web pages and PDF files. Users can highlight key passages, save excerpts, add comments, and share their findings across devices and platforms—all for free. This dual functionality makes LINER particularly valuable for anyone who spends significant time researching, studying, or curating content, turning passive reading into an active, organized knowledge-building process. Whether you're a student compiling sources for a paper, a professional staying on top of industry news, or a content creator gathering references, LINER AI streamlines the entire discovery-to-annotation workflow. Its cross-platform design ensures your highlights and notes follow you wherever you work, eliminating the friction of switching between disconnected tools.
