What is Liner?
Liner is an AI research assistant designed to help users discover information, analyze documents, and extract reliable insights faster.

The platform transforms traditional browsing workflows by letting users ask questions, summarize content, and organize knowledge from webpages, papers, and uploaded files. Its key differentiation is a research-first experience that emphasizes source visibility, citations, and evidence-backed answers rather than only generating text.

Current plans include free access alongside paid tiers offering expanded file uploads, advanced search, AI model access, and deeper research capabilities.
