Overview
Liner offers Deep Research on Free, Pro and Max plans alongside Liner Scholar for academic research, and gives access to 350+ models across providers. Free includes 100 credits a day and answers with ads; Pro is $17.99 a month ($14.99 billed annually). Team plans exclude data from AI training and Enterprise adds audit logs, but the pricing page does not name security certifications, and credit allowances cap heavy use.
