About EasySathi

EasySathi is built and maintained by an independent full-stack developer based in India. It started from a simple frustration: needing a quick GST or EMI calculation and having to wade through cluttered, ad-heavy sites just to find a working tool.

Every tool on this site runs directly in your browser — nothing you type or upload is sent to a server. That's a deliberate choice, not a limitation: it makes the tools faster, and it means your numbers and files stay yours.

The name “Sathi” means companion. The goal is for this to be the site you keep a tab open for — not a destination, just a reliable tool that's there when you need it.

EasySathi is actively growing. New tools and guides are added regularly based on what people actually search for and need. If there's a tool you wish existed, the contact page reaches a real person, not a form that disappears into a void.
