My trucks kept breaking. That’s the origin story. No garage, no shop room. A fleet of semis that wouldn’t stay running, and me trying to figure out why before the repair bills ate the month. So I built with Claude Code. It worked. Then I hit the wall every builder hits: I needed more compute than I could afford. Started Intent Solutions IO LLC, got accepted into the Google Cloud startup program, and got a pile of credits. Sat on them for months because I didn’t want to burn them on something dumb. Then Claude Code plugins shipped. Then skills. I bought for twelve dollars. Twelve. Then Anthropic shipped skills, so I grabbed Then Cowork, so I grabbed that one too. All three now point at I was still driving to make the bills. Kids’ soccer doesn’t pay for itself. Still driving today as I type via voice to text. Today that’s 470 plugins, 3,068 agent skills, 347 agents, 49.9K installs, 2,593 sta

MathIQ I built mathiq.io with Claude Code because I wanted a way for students struggling with college level maths to see how the problems can be broken down and not as intimidating. Each walkthrough goes from beginning to end and each step has a "why and how?" feature. Anon users get 1 free daily walkthrough powered by Haiku 4.5. Signed in users get 3 free daily walkthroughts powered by Haiku 4.5. Plus users get 5 Opus 4.6 walkthroughs plus 20 Sonnet 4.6. Pro users get 8 Opus/30

Free security + AI visibility scan. No signup needed. Just finished a project called [Shipleak]( https://www.shipleak.com ). You paste a URL, it runs 65 checks against the live site, takes about twenty seconds. Headers, TLS, cookies, CORS, DNS and email records, common exposed paths, and anything that looks like an API key sitting in your JS bundles. Then the AI visibility half: structured data, whether your content exists before JavaScript runs, whether AI crawlers are allowed, llms.txt. Eac

I built Torqmind – an AI-powered automotive diagnostic assistant. Looking for honest feedback. Hi everyone, I’ve been building Torqmind , an AI-powered automotive diagnostic assistant for DIYers and mechanics. The idea came from seeing how generic most online repair advice is. You search an OBD-II code or symptom and usually get a long list of possible causes with very little guidance on what to check first. My goal is to make diagnostics more practical by letting users select their vehic
