VERDICT

Should I use Liner?

Discover AI agents for professionals. Search with sources, research academic papers, and write clearly in one workflow with Liner. - liner.com

Worth it. Buy if you are a student, academic, or solo professional who needs source-cited AI search and literature-review help on a budget. Skip it if you need enterprise team controls — the evidence shows an individual research tool, not a shared workspace.

Confidence

Medium. Based on ~14 usable public sources; many search results named unrelated 'liner' products (pool, truck-bed, eyeliner) and were excluded.
