About Us
Jewellery shopping, reimagined
We believe buying a ring online should be effortless — no guesswork, no trips to the jeweller, no awkward string-and-ruler hacks.
The Problem
Why we built this
Ordering rings online is exciting until you realise you have no idea what size you are. Printable sizers warp, shipping ring mandrels takes days, and visiting a store defeats the point of shopping from your couch.
We asked: what if your phone could just tell you? With modern AI running entirely in the browser, it can.
The Solution
AI that respects your privacy
RingSize.AI uses Google's MediaPipe to detect 21 hand landmarks in real time. A credit-card reference gives sub-millimetre calibration. Everything runs on-device — your camera feed never leaves your phone or laptop.
Our Values
What we stand for
Privacy First
Zero data collection. No accounts. No uploads. Your images stay yours.
Accessible Everywhere
Works on any modern browser — mobile or desktop, no app install required.
Open & Transparent
We explain exactly how the algorithm works. No black boxes.
Results are estimates for guidance. For a guaranteed fit, confirm with a jeweller or physical sizer.
