Liner

What it does

Liner offers AI agents for three tasks: everyday search, academic work, and professional drafts. The search agent gives cited answers, the academic agent helps find and compare papers, and the writing agent helps shape emails, newsletters, and reports. The pricing page lists a free plan and paid plans with access to 350+ AI models.

Liner groups three AI agents under one product: Liner for search, Liner Scholar for academic work, and Liner Write for drafting. The homepage says the search agent gives cited answers and lets you check every citation with one click. It also mentions mind maps for complex topics. The academic agent can find and compare papers, add citations, and produce literature reviews. The writing agent turns a topic into a quick draft and helps shape emails, newsletters, and reports. The pricing page lists a free plan with unlimited advanced search, one file upload per day, and answers with ads. Paid plans remove ads, raise file upload limits, and add access to 350+ AI models, image generation, and Deep Research. The homepage links to API and MCP pages, but the text does not state usage limits or data handling details. The homepage mentions AI security and compliance and links to a learn more page, but the text does not give specifics. The free plan includes ads and a low daily file upload limit, so heavy users may need a paid plan. The homepage does not state whether an account is required to use the service.
