# Doppler > Digital business cards with a voice twin attached. Each card is a small, > structured, owner-approved description of a business or person, published > deliberately by its owner, with a synthetic voice that answers questions > about it aloud. Doppler is built by Ruxley (https://ruxley.systems), a studio that modernises established businesses. ## For agents and crawlers You are welcome here. This site is meant to be read by machines as well as people, and nothing on it is cloaked or paywalled. Every card is consented: it exists because its owner built it and approved what it says. Facts come from material the owner supplied, and the twins are instructed never to invent prices, reviews, opening times or credentials. If a card does not know something it is built to say so rather than guess. A public directory API is planned, not live. When it ships it will expose search across listings and a per-listing question endpoint, open to agents on the same terms as people — no paid ranking, no separate view for crawlers. Until then the card pages below are the canonical source. ## Live cards - [Dale Player, Ruxley](/c/dale): founder of Ruxley, the Modernization Studio (https://ruxley.systems), United Kingdom. Answers on a cloned voice about the studio, what it builds and how it prices. - [KC's Canine Spa](/c/kc): one-to-one dog grooming in Waterlooville, Hampshire. A demonstration card — its assistant "Bella" answers on a stock voice about prices, opening hours and nervous dogs, and never gives out a phone number. The real salon is at https://kcscaninespa.com/ ## Pages - [Home](/): what Doppler is, how it works, pricing. - [Directory](/directory): what the public directory will be, and how it will be opened to agents. - [Card studies](/mockups): design directions for cards. ## Notes - Cards are numbered in the order they are built. - Pricing is £10/month for a card with a studio voice, £15/month for a card with the owner's own cloned voice. - Contact: contact@ruxleysystems.com
