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.

On the Invoice, Quote, and Receipt generators, click the sparkle icon next to any Description field. Type informal notes about the work or items, and the tool sends them to Google Gemini and returns three polished, client-ready descriptions. Pick one — it fills the field. Free, optional, off by default until you click the icon.
Every URL scan is automatically analysed. Local heuristics catch URL shorteners, suspicious TLDs, IP-only hosts, punycode lookalikes, embedded credentials, and phishing-style keywords. Google Gemma adds a plain-English summary. Result is colour-coded Safe / Caution / Suspicious / Dangerous, and Dangerous links require a confirmation tap to open.
