About NagaiBook
We built NagaiBook because jewellery shops deserved better tools to run their gold savings schemes — simple, transparent, and built for the way they actually work.
Our Story
For generations, gold savings schemes have run on paper passbooks, registers, and trust. It works — until a register is lost, an entry is disputed, or a customer wants to know exactly how much gold they've saved. Shop owners were juggling notebooks, calculators, and WhatsApp just to keep it all straight.
NagaiBook was born to change that. We spent time with jewellery shop owners across Tamil Nadu — learning how they design schemes, collect installments, set daily gold rates, and settle at maturity. From those conversations, we built a platform that fits naturally into how a jewellery shop already runs, without asking anyone to change their trade.
Today, NagaiBook offers gold savings schemes, payment tracking, daily gold rates, a digital bill vault, new-arrival catalogs, and offers — with full mobile apps for both shops and customers, and complete Tamil and English support. Shops start free and keep every payment transparent.

Building Smart Tools for the Jewellery Industry
Selvaganesh founded SpyderAI Technologies Private Limited with a single goal — make technology work for people, not against them. NagaiBook is built from real conversations with jewellery shop owners who were tired of managing gold schemes with registers, calculators, and paperwork, and wanted a simpler, more transparent way to serve their customers.
Our Motto
"Spin Smarter with AI."
Our Mission
Every jewellery shop deserves professional tools — not just the big showrooms. We build software that is fast to learn, easy to use every day, and priced so that even a single-branch shop in a small town can afford it.
Our Vision
A future where jewellery shops and their customers are connected by trust and transparency. We are working toward a platform that handles the paperwork, keeps every gram of gold accounted for, and helps shops build lasting relationships with the families they serve.
