One system, your machine
Think it through. Watch it get made.
Talk it out in chat. DuoHand then opens the software you already own, does the work, and hands back the files — drawings, models, sheets, decks.
How deep it goes
Follow one collection, end to end
Jewellery is where DuoHand runs deepest today. Every step below is work it does in full, in your files.
I need a brief
Say who the collection is for and what it has to do. DuoHand asks the questions a designer would ask — occasion, price band, metal, stone budget, who the buyer is — and writes a brief the workshop can build from.
I need directions to choose from
It draws several, each with a point of view, and says what each one is betting on. You kill the ones that miss; it remembers why.
I need it checked
Mark up any sketch. When a change would thin a wall or crowd a setting, it says so and shows you the number before it draws.
I need this piece in other forms
One ring becomes a pendant, earrings, a bangle — proportioned against each other and sized to real hands and necks, not scaled copies.
I need a design sheet
Metal, stones, settings, tolerances and finishes, read off the model. Every figure on it comes from geometry rather than memory.
I need a deck by Friday
The book you put in front of a buyer, laid out from the same pieces, with renders made from the same files.
Measured, to the millimetre
Every line ends in a number the bench can cut to
Wall thickness. Seat width. Prong position. Tolerance. A model holds them and says when one is wrong, so the design sheet is read back off the piece.
Your workshop gets millimetres. Your client gets a render made from the same file.
A yes teaches it
What you approve becomes the line it holds for the rest of the collection.
A no teaches it more
The directions you kill are kept with the reason, so the same miss does not come back.
Your archive counts
Pieces you have already made are read as evidence of how you work, not as pictures to copy.
It argues from it
When a request would break that line, it says so before it draws.
Your own computer
Meets you where you already work
Install DuoHand Bench and connect it once. Duo then runs on your machine: it opens your files, drives your design software, reads what came out on screen, and reports every step. Anything that writes, runs or looks asks you first — once, for this task, or always.
Works in your files
Opens what is already on your machine and saves the work back beside it.
Drives the software you own
Illustrator and Rhino today, step by step, in the file you will hand over. The list grows as the hands do.
Checks its own work
It looks at what it made, compares it to what you asked for, and fixes the gap.
Asks before every move
Once, for this task, or always — you decide every time it wants to write, run or look.
What it hands back
Finished files, not conversation
A brief
Written from your answers, in the language a workshop reads.
Sketch directions
Several, each with a point of view and a reason.
A CAD model
Built in Rhino on your machine, in the file your bench already uses.
A design sheet
Metals, stones, tolerances and finishes, read off that model.
Renders
Made from the same file, so the picture and the piece agree.
A deck
Laid out in Illustrator, ready to present.

Every model worth using
It runs on all of them, and picks
DuoHand chooses per step — the sharpest model to argue about a direction, a fast one to answer a roll call, the right one to render.
When a better model ships it appears on the shelf. Your work stays where it is.

Who it is for
Built for people who make things
The designer working alone
You keep the judgement and lose the nights spent redrawing the same ring in three sizes.
The brand with a house style
It learns the line your collections hold and refuses to drift from it, season after season.
The workshop that gets the file
Millimetres instead of impressions, in the format already on the bench.
What it costs
Credit, spent as you work
No plan, no seat. Top up once and spend it as you work; every answer carries what it cost, so you always know where you stand.

Questions
The questions that matter
What is left for me to do?
The judgement. Which direction is right, what the client actually meant, when a piece is worth fighting for. DuoHand takes the hours that never made a collection better.
Will it design like me, or like the internet?
Like you. Every direction you approve and every one you kill teaches it your taste, and it holds that line across a whole collection.
What happens to work I have already done?
Bring it in. Old collections, sketches and photographs are read as evidence of how you work, and they sharpen what it draws next.
Can two people work on the same collection?
Yes. A collection is shared with the people you invite, and every decision on it stays with the piece rather than in someone's inbox.
Bring one piece. See what it hands back.
A brief, a sketch on paper, or a photograph of something you have already made.
