The WeChat Reading AI Skill has gained significant traction, appearing prominently in search rankings. Once users grant AI access to their WeChat Reading accounts, the intelligent assistant can facilitate book discovery, organize the bookshelf, and convert reading data into valuable insights. It offers six core functions, including bookshelf inspection and book search. Setting up this Skill is straightforward, involving two simple steps: initially deploying the Skill, followed by linking the account. Once configured, users can interact with the AI by posing questions. This Skill paves the way for innovative 'secondary creation of reading data,' empowering AI to conduct in-depth analyses of reading materials. For passionate readers, it serves as a highly intelligent reading companion. For the industry at large, WeChat Reading has successfully established a seamless ecosystem that combines 'personal data, large-scale AI models, and context-aware services.' This development suggests that the future competition in knowledge products will hinge on the ability to deeply 'understand users'.
