Liner Unveils Deep Research: 'Faster and more accurate than OpenAI, Perplexity'

AI search startup Liner has broken new ground in AI search by introducing 'Liner Deep Research,' disrupting conventional approaches. This innovative feature goes beyond simple searching to deeply analyze vast amounts of web data and generates sophisticated answers that penetrate the essence of questions through advanced logical reasoning. The core is to convert users' complex questions into detailed research plans, providing deeper, richer, and more accurate information. Accessibility is also excellent. Anyone can easily experience advanced AI research as it can be used for free up to 10 times daily without separate login or subscription. It starts immediately by simply clicking the 'Deep Research' button below the Liner search bar, and users can receive results that enhance the depth and logical coherence of answers by referencing significantly more sources than existing services. The most prominent strength of Liner Deep Research is its unrivaled accuracy. Liner's technological prowess shone brightly in SimpleQA, an AI fact-checking benchmark. In particular, 'Liner Reasoning,' which strengthens deep inference capabilities, achieved a top score of 95.3 points, demonstrating results that surpassed OpenAI GPT-4.5 (62.5 points) and Perplexity Deep Research (93.9 points). This objectively proves the reliability of the information provided by Liner. It is also unparalleled in speed. While Perplexity Deep Research requires an average of 35 minutes and OpenAI Deep Research takes about 10 minutes for answer generation, Liner Deep Research completes search and analysis in just 12 minutes, providing insights to users at a speed at least three times faster than competitors. Kim Jin-woo, CEO of Liner, emphasized that this Deep Research was "not only developed to perform advanced research by maximizing inference capabilities, but also to be the most reliable AI research providing trustworthy information." He expressed his ambition that, based on Agentic Search technology, Liner would stand shoulder to shoulder with big tech companies in the global AI search market and push beyond the limits of AI search. With 11 million users worldwide, Liner is expected to further solidify its position in the global AI search market with the launch of this Deep Research.
