kei31.com is more like a personal content hub for “AIマンガ家けいすけ” than a conventional course website. The page brings together links to his new Brain teaching material “プログラム詰め合わせパック,” the Udemy course “Claude CodeでAIプログラミング入門,” Kindle books, note membership, Substack, YouTube, email newsletter, and several Discord/LINE community entry points. Its core focus is AI manga creation, AI-assisted programming, and personal content distribution for creators.
In terms of subject area, the page clearly covers AI manga, introductory AI programming, and bundled programming resources, making it relevant for people interested in hands-on generative AI creation. The teaching formats are relatively scattered: Udemy usually means recorded video courses, YouTube provides public videos, while Brain and note are more likely to be text-based or resource-oriented paid content. However, the page does not disclose course length, syllabus, assignments, live sessions, or 1-on-1 services. There is no mention of certification or certificates. The teaching language appears to be Japanese, so Chinese-speaking users will need Japanese reading ability or translation tools. As for instructor background, けいすけ operates across multiple platforms as an “AIで描くマンガ作家” and has Kindle books and course content, but the page does not provide more formal educational credentials or detailed project case studies.
Pricing information is insufficient. The page only states that the new Brain material is a bundled collection of programs and notes that the price will gradually increase as new works are added, suggesting that the current timing is relatively good value. However, it does not disclose the exact price, refund policy, or what is included. Other channels such as note membership, Substack, Kindle, and Udemy may also charge separately, so learners need to visit each platform to confirm the details.
The strengths are its focused theme and wide range of channels. It suits users who want to follow a Japanese AI manga creator’s ongoing practice over the long term, especially those looking to obtain program resources, watch introductory AI programming content, or join AI manga communities. The drawbacks are that information is scattered, and the site lacks a systematic course outline, learning path, certificate information, service support, and pricing transparency. It is not very friendly to users who simply want to buy a structured course.
Access from mainland China cannot be determined from the page text alone, and since it relies on platforms such as X, YouTube, Substack, and Discord, actual usage may involve network or account restrictions. Payment options also depend on platforms such as Brain, Udemy, and Kindle. Alternatives include other AI programming or AI drawing courses on Udemy, as well as AI drawing and AI manga courses on Chinese platforms such as Bilibili, 知识星球, and 小鹅通.
