AI usage in my articles and verbosity

All articles that I publish are self-crafted, but I use AI to make the articles better. The four main areas are:

All of this is done to compensate for my language gaps. I genuinely think that AI English is better than mine. I don’t use AI to make articles longer. I always assume that readers of this blog are not only low-level geeks, but also high-level Java developers, who may not know low-level stuff. That’s the reason for the verbosity of my articles.

Since 2026, in the majority of my investigations I use AI as a tool to speed them up. If something useful is generated by AI during such an analysis, I can also paste it into the article. For example, the table with the ASM -> pseudocode translation from this article was AI-generated. Since 2026.09 I will try to be more transparent about AI usage in each article, probably with a chapter at the end.

I created some tools that help me with profiling big application with Async-profiler:
