About ChrysoKit
ChrysoKit is a small, growing collection of free online utilities designed to solve common everyday tasks without friction. No sign-up forms, no paywalls, no "download our app" banners — just the tool you came for, ready to use.
What's here
Right now you'll find eight tools covering passwords, QR codes, text stats, quick maths, currency and unit conversion, focus sessions, and basic health metrics. The list grows whenever a new tool earns its place — the bar is: it has to do one thing well, fit on one screen, and not need an account.
How it works
Every tool on ChrysoKit runs entirely in your browser. When you generate a password, convert a currency, or create a QR code, the computation happens on your device. Your inputs — the text you type, the values you enter — are never sent to any server.
Why it's free
ChrysoKit is supported by unobtrusive ads on the pages. That keeps the tools themselves free to use, with no limits, no trial periods, and no premium tiers. If you find something useful, the best thank-you is to share the link with someone else who might need it.
