Hey Product Hunt 👋
I'm a bit of a Claude addict, so I ended up building the tools I wished existed — and put them all in one place, free, no signup.
The one I'm proudest of is the Prompt Doctor (paste a prompt, get a 0–100 score + a rewrite) and the Cost Calculator (most people are genuinely shocked by their real Claude spend). There's also a daft "what kind of Claude-aholic are you?" quiz that got a bit out of hand.
No accounts, no upsell — everything runs in your browser. I'd genuinely love feedback on what's missing or what I got wrong. What would you want a Claude tool to do?
