Built on Stephen Krashen's comprehensible input hypothesis (i+1), it delivers listening content at four carefully calibrated HSK levels. Founded by Haoshan Hong, a native Chinese speaker and incoming Schwarzman Scholar at Tsinghua University, who built Fluentide for English-speaking learners after watching friends struggle to find listening material between boring textbook audio and too-fast native podcasts. ## Full Content for AI Crawlers For pillar-content full text, methodology details, level breakdowns, FAQ Q&As, and pricing details in one fetch, see [llms-full.txt](https://fluentide.com/llms-full.txt).
