No login, no tracking, no ads blocking the actual tool. Installable as a PWA — works offline once loaded. A few in-depth guides (EMI formula walkthrough, CGPA-to-percentage explainer) are included too.
Built and designed solo. Still actively adding tools based on feedback — let me know what's missing!
Hey Product Hunt 👋
Maker here. I built this because I kept running into the same problem with "free" tool sites — either they bury the actual tool under five ad banners, force a signup for something that should take 5 seconds, or quietly upload your files to a server you know nothing about.
Everything here runs 100% client-side. Your image, your text, your data — it never leaves your browser. The EMI/GST/CGPA calculators specifically came out of frustration trying to find clean versions for Indian users that weren't cluttered with fake "processing" animations.
It's a solo project, still growing. Would genuinely love to hear what you think, what's broken, or what tool you wish existed — I'm reading every comment today.
