About

Tools that work without an account or upload

Every tool here runs entirely in your browser. QR codes are generated client-side. Invoice PDFs are built with pdf-lib directly on your device. EMI calculations and unit conversions never touch a server. Your data stays private.

The Invoice / Quote / Receipt Generators all include an optional AI line-item writer — type informal notes, get three polished descriptions back, powered by Google Gemini. The Invoice Generator supports 7 tax regions with correct logic for each: India splits CGST+SGST automatically, Canada auto-fills HST/GST/PST by province (including Quebec QST), EU handles reverse-charge for B2B. Sign in with Google to sync your profile and invoice history across devices.

The QR Code Scanner now runs an automatic AI safety check after every scan — phishing-style URLs, lookalike domains, hidden shortener targets, and embedded credentials are flagged before you open them. The EMI Calculator includes a reverse mode and a full year-by-year amortization table.
