AI-assisted, programmer-built desktop apps

twoplus11 offers several dozen utilities for macOS and Windows, free for personal use. According to the author, these are AI-assisted apps rather than hands-off exercises in vibe coding: "I used AI as a coding assistant while building Blockr. I am a full-time software developer, and working with AI is just a part of development now. The design decisions, the security review, and the testing are mine, and I'm the one who answers when it breaks."
