I’ve had the idea of building my own version of Jarvis in the back of my mind for a while, and recently I decided to finally give it a shot.
I started experimenting in Codex and quickly began putting things together, but I was already tired and probably a little too impatient. Because of that, I rushed through the process, made a lot of messy decisions, and ended up with something that was honestly incredibly unusable.
That said, starting over from scratch has never really scared me. Ever since I was around 15 and constantly sitting in front of a PC, one thing I’ve never been afraid of is deleting everything and rebuilding properly. So that’s exactly what I did.
On my second attempt, things somehow got even stranger. Even though I was using GPT-5.4 in Extra Thinking mode, it felt like the AI got stuck in a loop. No matter what I said, it kept doing the same things over and over again. I’m not sure if it was a bug or just a prompting issue on my side, but it definitely slowed me down.
I also realized that relying on different AIs to help me write better prompts is making my workflow much slower than it should be. I clearly need to get better at prompt engineering and learn how to work with these tools more efficiently.
In the end, I deleted the second version too. I guess today just wasn’t my day, and I couldn’t manage to build something solid enough that I actually liked.
