Cup Caps is the first real-time tracker for the hidden water cost of your AI queries — and then it connects you directly to the organizations working to protect it.
💧 Add to Chrome — It's FreeCup Caps runs quietly in your browser. You use AI normally — it handles the tracking.
Data centers use enormous amounts of water to cool their servers. That cost is invisible to users — Cup Caps makes it visible.
AI uses more water than most people realize — from rural aquifers across the United States to communities worldwide without clean water access. These organizations are working to protect it. Cup Caps links directly to each one — we never handle donations.
Free to install. 15 seconds. No account needed. Your AI usage has a water footprint — now you can see it and do something about it.
🧩 Add Cup Caps to Chrome — FreeCup Caps is built by one person. Your ideas, bugs, and requests go directly to me — and the best ones ship. Tell me what you'd want to see.
Hi, I'm Sabrina (you found me 😉). I built Cup Caps because I use AI tools every day and started wondering what that actually costs. Not in dollars though, but in water. This is my attempt to make that visible. It's free, it's a WIP, and it's just me! If you find this tool useful to you, I'd love your support.
