The user, who built a personal AI assistant named Kai, identified inefficient GPU usage in a custom web app, replaced a file-sharing service with a self-hosted solution, and created a minimalist menu bar stats app called ulbar.io.", "body_md": "Just had another crazy experience with AI last week. One of the types that reminds me that we're living in different times.\n\nI have been suffering for months with some pretty serious macOS performance issues. My GPU bar was always pegged. I was having massive CPU spiking issues, and in general my UI felt massively slow.\n\nRaycast took forever to load. It took forever to find things, and even after I selected something, it still took forever to actually happen.\n\nAnd I kind of intuitively knew that there was something just rotten about the system.\n\nSo yesterday I decided to fix it, finally. I had Kai, my [Digital Assistant](/blog/personal-ais-will-mediate-everything), walk me through a troubleshooting process.\n\nSo what I thought was a Chrome issue turned out to be one of the custom web applications that I had built was doing some really inefficient GPU usage. So I fixed that in like 10 minutes.\n\nAnd then I have been paying for one service that helps me share files with people of whatever size. Just by doing a keyboard shortcut or a right-click menu selection.\n\nI was paying a few hundred bucks for this per year, but it's also another app that is running.\n\nSo I [remade that app myself](/blog/ai-enabled-self-software), hosted within my own infrastructure, within like an hour. So now I can share files basically for free and the app is basically zero performance cost.\n\nThen I realized that my Stats app in the menu bar was taking a decent amount of resources. And iStat Menus does as well. So I remade that app, which is now [ulbar.io](https://ulbar.io). Super fast and minimalist replacement.\n\nOh, it also realized that I had a bunch of macOS widgets for FindMy and Weather and that those were seriously junking things up too.\n\nWell, after making these few changes, I am now spending less money per year, and my system is lightning fast. It's like I have a completely new computer. Raycast has zero problems. Wispr Flow is working way better. All my apps are massively improved, and I've turned the whole concept into a skill that actually runs regularly to see if I have anything chugging up the system.\n\nIt's absolutely insane that I could just replace things that are macOS apps myself in less than an hour, including having a website, showing it off, and even selling it if I want to. Again, all in less than an hour.\n\nI feel like tech right now is as different from five years ago as five years ago was from twenty years ago. 🤯", "url": "https://wpnews.pro/news/another-crazy-experience-with-ai", "canonical_source": "https://danielmiessler.com/blog/ai-fixed-my-mac?utm_source=rss&utm_medium=feed&utm_campaign=website", "published_at": "2026-08-15 19:35:00+00:00", "updated_at": "2026-08-15 19:40:50.729890+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-tools", "ai-products"], "entities": ["Kai", "Raycast", "Wispr Flow", "ulbar.io", "iStat Menus", "macOS"], "alternates": {"html": "https://wpnews.pro/news/another-crazy-experience-with-ai", "markdown": "https://wpnews.pro/news/another-crazy-experience-with-ai.md", "text": "https://wpnews.pro/news/another-crazy-experience-with-ai.txt", "jsonld": "https://wpnews.pro/news/another-crazy-experience-with-ai.jsonld"}}
