How I Track AI Token Usage Across OpenAI, Claude, and Cursor Without Opening a Dashboard

I've been thinking a lot lately about how quietly AI tools have become essential to my development workflow. Between ChatGPT for brainstorming, Claude for deep code reviews, Copilot in VS Code, and Cursor as my daily editor, I'm basically swimming in AI-powered features. But here's the thing that kept me up at night: I had no idea what I was actually spending. Every few weeks, I'd get that moment of panic. I'd log into OpenAI's dashboard and see charges that made me go "wait, what?" I'd open Claude's account page and squint at some vague usage stats. And honestly? I'd just close it and try not to think about it. Which is a terrible strategy, but also... relatable? The Dashboard Fatigue is Real Let me paint the picture. You've got: OpenAI's dashboard (nice, but you have to remember to check it) Claude's usage page (buried somewhere in settings) Anthropic's billing (different from Claude web) Cursor's usage (if they show it) GitHub Copilot costs (comes out of your GitHub Enterprise bill
