Every card says the same nothing
A name, a title, a company. None of it answers the only question the other person actually has, which is whether you can help them. Yours is the one that can answer it — and the one they show a colleague afterwards.
AI-Native Digital Business Cards
The business card that answers back.
Tap, scan or send a link. Behind every card is a voice twin — trained on what you do — that answers the questions you would otherwise have to be there for.
QR code, link and vCard sharing
Answers out loud in your own cloned voice
A context window for every teammate
Why bother
A business card used to be a direct line.
Before email, a card got you past the switchboard. A name, a company, an extension that rang on somebody's actual desk — it was worth keeping because it did something. Then the internet arrived and the card became a formality: a rectangle you accept, pocket, and never look at again.
Most digital cards just re-stage that ritual on a phone. If all it does is hand over an address, you may as well have sent the email. What has actually been missing isn't the contact details. It's everything around them.
Ask it what you'd have emailed
“Do you handle this sort of thing? Have you done it before? What does it cost?” The questions people never quite get round to sending. Asked at eleven at night, answered in your voice, from facts you approved.
And it saves itself
One tap writes you into their contacts, with the twin still attached. A week later they search your name rather than their pockets — and can still ask it something.
How it works
Ten minutes of talking. Then it's live.
There's no app to learn and nothing to configure. You have one conversation, we build the twin, and the card works everywhere a link works.
01
You talk for ten minutes
We interview you the way a good journalist would — what you do, what people always ask, what you're happy for it to say, and what's off-limits. That recording does double duty: it's your context, and it's the voice sample.
Five seconds of clean audio is enough to clone a voice. Ten minutes is enough to have something worth saying.
02
We build the twin
The interview becomes a context window: an approved set of facts the twin can use, and boundaries it won't cross. Your voice is cloned, or you pick a stock one if you'd rather the twin sounded like the brand than like you.
You approve every answer before anyone else hears one.
03
You hand it over
Let someone scan the QR, drop the link in an email signature, a WhatsApp bio or a link page. However it arrives, they land on your card, save your contact, and can ask the twin anything.
Same context window later powers your site, your app, your careers page.
Live cards
These are real, and they're talking.
Not mock-ups. Two working cards, built on the same system, each one wired to its owner's own context and voice. Open either and ask it something.

The next card is somebody's. Cards are numbered in the order they're built.

It gets better
The more it's asked, the more it knows.
Your card writes down every question anyone puts to it — including, especially, the ones it couldn't answer. Those come back to you as a short list. Answer one in your own words and it's recorded in your voice, permanently, in every phrasing someone might use to ask it.
Most cards are as good as they will ever be the day you're handed them. This one is at its worst on day one.
01
It keeps notes
Every question, and whether it had a good answer. You get the thing no business card has ever given anyone: a record of what people actually wanted to know, in their words, at the moment they wanted to know it.
Ask it something twice and the second person gets the answer instantly.
02
You answer what it missed
Answer it however you'd say it in the van — a few rough words is plenty. We turn that into the answer you'd have given with time to think, using what you wrote and the context your card already holds. Never anything from thin air. Then you read the exact wording and change whatever you like before it's recorded.
Nothing goes on your card that you haven't read first.
03
Or teach it on purpose
You don't have to wait for strangers. The fastest way to make your twin good is to sit down and ask it the things your customers ask you — the awkward ones, the price one, the one you're bored of answering. Everything it fumbles lands on your list.
Half an hour of quizzing it is worth a month of waiting.

FAQs
The questions people actually ask.
What stops it saying something mad in my name?
The twin can only work from a context window you approved — the facts about you and your business, written down and signed off. It's told, explicitly, to say it doesn't know rather than guess, and to send people to a real human when it's out of its depth.
We also write hard boundaries in: a groomer's twin won't give veterinary advice, and it won't invent a customer review. You see every stock answer before the card goes live.
Do you clone my actual voice? Is that safe?
Only if you want it. It takes a few seconds of clean audio, and the card says out loud that it's the AI version of you, not you. We only ever clone the voice of the person who sat in the interview and asked us to.
Plenty of businesses choose a stock voice instead — that's a brand assistant rather than a clone of the founder, which is often the better call for a team or a shop. KC's Canine Spa is built that way on purpose.
What if nobody ever talks to it?
Then you still have the best-looking card in the room, and it still saves itself into people's phones. We'd rather say that plainly than pretend every contact becomes a conversation.
The twin earns its keep in the follow-up, not the handshake: the person who was interested, a day later, with a question they'd never bother emailing you about.
Is it a physical card, or just a link?
It's a link — which is why it works everywhere: a QR code, your email signature, a WhatsApp bio, a social profile, or printed on the back of an ordinary card. Nothing to post out, nothing to lose, and you can change what it says after you have handed it over.
Can it book things, or does it just talk?
Today it answers and hands off — it'll take someone to your email, your phone, your booking form. Live diary booking is what we're building next, and it's where the twin stops being a nice card and starts being an employee.
Who's behind this?
Doppler is built by Ruxley, a studio that modernises established businesses — sites, films, and AI agents that do real work. The card is usually the smallest, fastest thing we can build for someone. It's often not the last.
