Liner AI

Liner AI is an AI-powered search, research, and writing platform built for professionals who need fast, reliable answers backed by sources. It combines three purpose-built products - Liner for everyday search, Liner Scholar for academic research, and Liner Write for professional drafting - so users can move from finding information to producing polished output in a single workflow. This makes linear AI especially valuable for marketers, consultants, researchers, students, product teams, and content creators who need to fact-check claims, compare sources, generate literature reviews, and draft documents without switching tools. Its biggest strength is precision: cited answers, follow-up questioning, paper comparison, citation support, and editing in a single interface help reduce guesswork and speed up work. With AI security and compliance messaging, plus an API for developers, Liner AI positions itself as a trustworthy, productivity-focused assistant for knowledge work.
