AI-native product development for physical-product teams
Build with AI.
Keep the product coherent.
DesignBuilt turns parallel product inputs into human-confirmed decisions—then keeps those decisions connected across versions, design tools, prototypes, suppliers, variants, and production.
For small, design-led physical-product teams. Starting with furniture.
Creation is abundant. Product coherence is not.
The decision and continuity problem
AI, references, CAD, prototypes, and suppliers all produce useful inputs. None of them knows which conclusion the team accepted, which version it applies to, or what a later change invalidates.
Compare parallel inputs
Align model outputs, references, artifacts, and objections without flattening disagreement or uncertainty.
Carry forward a human decision
Only a confirmed Candidate becomes a versioned Product Basis that can govern the work that follows.
Embedded workflow demo
Form, hand off, and verify a contract-chair prototype decision.
A furniture brand is preparing a chair for a 240-unit hotel order, with two finishes and a project-specific variant. One bounded seat-depth test proves how a decision can form in one model, continue in another, reach the workshop, and remain coherent when physical feedback returns.
Guided demo · This prototype follows the P03 confirmation path. Other decision options remain selectable to show where human authority applies.

Review the professional workspace on a larger screen.
Compare Claude, ChatGPT, and Rhino inputs; generate a Candidate; then decide whether P03 should become a separate test-only Product Basis.

Submitted excerpt
“The current 470 mm seat depth may not provide the intended lounge comfort for H01. Consider testing a deeper seat before carrying this direction forward.”

The technical proof contracts
A professional job on the surface. Verifiable continuity underneath.
Form the decision
Frame one product question, compare parallel inputs horizontally, and keep disagreement and missing evidence visible.
Share one Product Basis
A human-confirmed decision becomes an explicit basis that another model or collaborator can continue from.
Round-trip a Bounded Slice
The workshop receives controlled context and can return a fabrication proposal without rewriting the source product reality.
Return and verify the artifact
A change is complete only when a revised artifact, execution receipt, or explicit human verification comes back.
Package and Bounded Slice
Give the workshop what it needs—without giving away the whole project.
A Package tells the fabricator what to do. A Bounded Slice lets them understand, question, and continue the relevant product logic in a new controlled context—never inside the publisher's native thread.

The next professional outcome
DesignBuilt begins with what needs to be ready next.
Product Framing Brief
Decision target, intended outcome, scope, constraints, source set, and the questions still open.
Prototype Build Package
Approved test basis, critical dimensions, fixed intent, allowed variation, and validation plan.
Supplier Deviation Review
A proposed substitution framed with constraints, evidence, impact, ownership, and approval path.
Variant or Release Package
Exact branch basis, current artifacts and BOM, locked requirements, open items, and recipient scope.
Technical boundary
One product reality. Different tools participate honestly.
Model-neutral. Host-native. Adapter-mediated.
DesignBuilt does not migrate native conversations or promise universal CAD writing. Supported hosts exchange selected Candidates and Product Basis requests; artifacts participate through the capabilities their adapters actually provide, with human execution and verification when needed.

Furniture first. Architecture-capable.
A focused vertical with a credible path into prefabrication.
DesignBuilt begins where we can validate the workflow deeply: furniture products moving through design, prototypes, suppliers, variants, and production release. The same product-development structure extends naturally into manufactured interior systems and prefabricated building components.
Furniture product development
Design intent, components, dimensions, materials, workshop proposals, prototype decisions, variants, and production packages. The contract chair is the enterprise scenario inside this vertical.
First verticalArchitectural millwork & configurable interiors
Repeated room packages, project-specific configurations, client approvals, site interfaces, finish systems, and batch manufacturing.
Expansion wedgeConfigurable prefab components
Product families, formal release gates, code constraints, installation interfaces, factory feedback, and configuration control.

DesignBuilt
From design intent to production reality.
DesignBuilt helps small physical-product teams make the next consequential decision and prepare the next piece of work without losing the Product Basis that makes either one trustworthy. We are looking for professional furniture workflows that can challenge the working prototype.
