Liner Adds Cover Letter Analysis and Interview Prep to Liner Lite

Driven by young users

Liner says the update reflects what it saw in usage data. Since Liner Lite launched, young people have been prominent users, and many use it for cover letters and other job preparation. As of the end of October, about 53% of users were aged 18 to 24, mostly university students and early-career workers.

The company has built out the cover letter feature step by step. It launched on PC web in May, reached mobile web in July and the mobile app in August. The latest update goes beyond writing and editing into analysis and interview practice.

Scholar and Router API

Liner also improved the paper comparison and analysis tools in Liner Scholar, its academic research service. Users enter a paper title or research topic, and the service finds related papers, adds them to a comparison table and generates analysis using the same criteria. The change is meant to spare researchers from rebuilding the table each time they add a paper.

For businesses, Liner launched the Liner Router API. It automatically assigns a suitable AI model based on the difficulty and type of each question, aiming to improve cost efficiency. The company added a feature showing which model and how much cost went into each response, and introduced a pricing scheme that reflects per-model costs.

CEO Kim Jin-woo said Liner has widened its services from information search to academic research and writing based on user feedback. He said the company plans to keep raising research and work productivity while expanding into mobile agent services that help solve everyday problems.
