At the "Annual Technology Innovation Sharing Conference" held last night, Luo Yonghao announced that his startup "Thin Red Line" has officially launched its self-developed AI product - "Qie Ting". This product is positioned as a deep voice library for the AI era and is now available on all major app stores.

"Qie Ting" relies on natural language processing (NLP) and knowledge graph technology to structure books. Its core selling point is **"Deep Explanation"**: each book is explained for 1-2 hours, with over ten thousand words, aiming to extract core ideas for users, suitable for fragmented deep learning scenarios such as driving commutes.

At the press conference, Luo Yonghao demonstrated the product's voice customization feature, successfully generating a personalized voice model by uploading the voice of stand-up comedian Niao Niao.

Currently, "Qie Ting" has integrated multiple category lists including Douban Top 250, covering disciplines such as literature, economics, and psychology, trying to solve the user's "book selection difficulty" pain point. In terms of pricing, the product adopts a highly competitive low-price strategy: 9.9 yuan per month, and only 37.8 yuan per year. In addition, new users who register will receive a 7-day membership, and there is also a friend invitation incentive mechanism.

As an initial exploration of Thin Red Line in the AI content field, "Qie Ting" has also attracted industry attention after the on-site demonstration. Although the technical performance is impressive, the product still needs further market validation and official responses regarding core issues such as book copyright compliance, extension of practical application scenarios, and long-term user acceptance of this "AI-explained" reading mode.
