About Liner
Liner is a web-based set of AI agents for professionals, combining AI search, academic research, and writing in one workflow. Its search feature returns cited answers, with the option to check each citation, ask follow-up questions, and view complex topics as mind maps. For academic work, the homepage describes finding and comparing papers on a topic, adding citations to a paper, and generating literature reviews, which it attributes to Liner Scholar. For writing, it describes generating a first draft from a topic, shaping ideas into documents such as emails, newsletters, and reports, and editing and verifying drafts, which it attributes to Liner Write.
The homepage names Liner, Liner Scholar, and Liner Write, but does not explain how they differ or whether they are sold separately. It states that Liner aims to make AI use responsible and safe, but it does not describe data handling or give specific security or compliance details. Pricing is not stated on the homepage.
