Would you use a brainstorming/planning/ideation tool for side projects? This is not a new idea, and I know we see posts about something similar about once a month. I do think I took it farther than others I've seen, but either way I'd still be interested in feedback on this one. Backstory: I've been building side projects with AI a lot (who hasn't?) and I realized that over the past year I've gravitated toward a very structured approach for building new ideas. I define it, research competit

I don’t know why isn’t it getting that much attention it’s actually a big deal for people who do vibe coding, for people like who develop micro apps daily. As a teacher it’s so ise to just tell students to go to and practice tables… It’s so amazing

An FPS game built as a parent-friendly alternative to Roblox.

I'm a father of two, 7 and 12. They are obsessed with Roblox, especially Rivals. Like a lot of parents, we did not love it. We tried the usual things: block it, limit it, set timers." It became a daily battle, a lose-lose situation. So I flipped the problem. Instead of fighting what they loved, I decided to lean into it, but with a twist. Why just play an FPS when you could build one together? My kids became the PMs. Claude and I became their engineer. I was shocked by how fast we moved. We picked a name, Cooked and started building. Get in. Lock in. Get cooked! In the first 3 hours, we had an actual FPS we could play together in the browser. Next day I invited my friend's two kids over. Suddenly, I had four PMs. We had 3 laptops, 1 iPad and 1 iPhone. So in 30mins we added mobile support and could play all 5 together. The kids would ask for features: "Can we have a rocket launcher that knocks people off the map?" "The knife should stab faster when you hold it." I know al

A friend taught me a Slovenian card game two days ago. GPT-5.6 Sol helped me turn our argument into an AI opponent. Two days ago, a friend taught me Sedmice, a traditional card game we play in Slovenia. The rules are simple, but we quickly got into an argument about the best moves. Naturally, I decided the reasonable way to settle it was to build an AI opponent. I wrote out the rules, project specification, architecture, and implementation details, then handed the logic to GPT-5.6 Sol. Ab
