Liner

Liner is a set of AI agents for professionals that search the web with sources, research academic papers and write documents. It has three products: Liner for AI search, Liner Scholar for academic research, and Liner Write for drafting and editing work documents. Each is built for a different kind of task, and all three can be used with one subscription.

The page describes Liner as being for people whose work depends on accurate information. The testimonials come from marketing consultants, content researchers, product managers, master's and PhD students, research scientists, business strategists and customer success managers. Answers include citations that can be checked with one click, and follow-up questions and mind maps help with complex topics.

Liner Scholar helps users find and compare papers on a topic, suggests citations for a paper and builds literature reviews. Liner Write produces a quick draft from a topic, shapes ideas into emails, newsletters and reports, and supports editing and verification in the same window. Liner Write and Liner Scholar currently run on desktop only. Liner's search product is available on iOS, Android, Mac, Windows, Chrome and Edge.

The free plan costs $0 and includes unlimited Advanced Search, one file upload a day of up to 25MB, and answers with ads. Liner Pro costs $17.99 a month, or $14.99 a month billed annually. Liner Max costs $35.99 a month, or $29.99 a month billed annually. Both paid plans give access to 350+ AI models, image generation and Deep Research, and remove ads. The Team plan costs $26.99 per seat a month for 2 to 20 members, and Enterprise pricing is available on request.

The page also states that Liner is dedicated to making AI use responsible and safe.
