What it is

tw93.fun is an original technical blog run by Tw93, an independent product engineer based in Hangzhou, China. It focuses on sharing content about AI implementation, AI Coding practice, industry insights and investment perspectives. The author also develops multiple open-source AI-assisted tools during his spare time, which are hosted on the blog for public use. The blog has a clean, ad-free interface, and all content is based on hands-on practical experience rather than vague, generic industry concepts.

Core Features & Pricing

The blog itself is completely free and open to the public — all original articles are available to read for free. All the author’s projects, including Kaku Terminal, Pake App Packager, MiaoYan Writing Tool, Waza Claude Code Skill Set, and Kami AI Typesetting Tool, are fully open-source and free to use. You can access the source code and use all features without any paid subscription.

Its core content covers cutting-edge AI topics such as Claude Code practical guides, embodied intelligence, large model training, and Agent principles, alongside in-depth think pieces on tech investment and industry observation. It also supports full-text search to help users quickly find the content they need.

Pros and Cons

Pros

• The content is thoroughly in-depth, all drawn from the author’s own first-hand experience. Many of the Claude Code tips shared here are rare publicly available summaries in the industry, and even non-technical users can follow the tutorials to start doing AI Coding.
• Clean, ad-free interface, fast loading speed, and smooth search experience.
• The author’s multiple open-source tools are highly targeted, and solve many real pain points in AI development.

Cons

• Content is focused on personal experience sharing, and lacks a systematic course framework. It is not suitable for users who want to learn AI systematically from scratch.
• Open-source tools only offer community support, with no official commercial after-sales service. Enterprise users use these tools at their own risk.

Who It’s For & Accessibility in China

The website is currently directly accessible in China with no VPN required. It is a great resource for AI developers, product managers, non-technical users who want to get started with AI Coding, and users interested in tech investment.
