SILVIA AI INTRODUCES

Supra

The engineering execution layer for physical products.

State the objective. Supra plans, builds the geometry, runs the checks, wires the systems, and preps the release. A human stays in charge, and everything goes on the record.

PROMPT

State the objective.

Plain language, hard constraints. Nothing is built yet.

PLAN

It plans before it builds.

The work decomposes into a parts manifest. Your constraints lock first.

BUILD

Parametric geometry, feature by feature.

Real CAD solids assemble part by part. Never a dead mesh.

VERIFY

It finds the failures first.

Clearance, walls, fasteners, fit, interference. Obvious failures auto-fix.

SIMULATE

Loads, heat, and flow, checked.

Structural and thermal behavior, before anything is cut.

SYSTEMS

Circuits, harness, firmware.

Wired to the exact hardware in the geometry.

STRATEGY

Variants ranked. Mass down 23%.

The design space swept, every candidate fully checked.

RELEASE

Release-ready, on the record.

STEP, STL, BOM, firmware, and the full verification ledger.

Try it

Poke at the work.

Every claim on this page is something you can move, toggle, and watch respond. No video, real geometry.

Simulation you can toggle.

Stress, thermal, and airflow on the same bracket. Switch the analysis and read the result off the part.

PEAK STRESS 184 MPa FoS 2.1

Grown, not drawn.

Fix the bracket at its bolt hole, load the free corner, and the optimizer keeps material only along the stress path, the way trabecular bone does (Wolff's law). Generate it, or scrub between the dense fill and the optimized result.

Virtual proving ground

Tested before it exists.

Every design runs the gauntlet virtually: wind tunnel, loads, thermals, endurance, before a single part is made.

Illustrative potential-flow approximation. Drag to orbit.

Electronics, end to end

From intent to fabricable board.

Not just the shape. Supra places the parts, routes the copper, stacks the layers, then checks it. Step through an illustrative reference layout.

Structures, systems, power

It designs the whole building.

Structure, envelope, mechanical systems and power, coordinated on one model. Switch systems and read each off the building.

Illustrative building model, representative values

CAD. Checks. DFM. BOM. Firmware. Docs.

Hardware still ships through a maze.
Supra makes it one loop.

  1. 01

    State intent

    Objective, constraints, what done looks like, in plain language, or from a photo of the thing you're building around.

  2. 02

    Plan

    Supra proposes the steps and asks only what's critical. Nothing builds until you say so.

  3. 03

    Build

    Editable, parametric geometry, never a dead mesh. Sized to real components' datasheet dimensions.

  4. 04

    Verify

    Fit, clearance, printability, interference. Failures surface in seconds, the obvious ones fix themselves and get re-checked.

  5. 05

    Release

    STEP, STL, BOM, firmware, build guide, revision notes. A design state you can hand to reality.

Everything between
intent and reality.

Point tools optimize one step. Supra owns the whole path, and every claim it makes is labeled estimated or validated.

Plan-first agent

Supra shows its full plan, constraints, assumptions, open questions, before a single feature is built. One-click approve or revise.

Parametric build

Prompt-to-parametric parts on a real BREP kernel. Editable dimensions with typed bounds, exact STEP + STL export. Never a dead mesh.

Verification ledger

Every check records its method, measured value, assumptions, and residual risk. Trust through visibility, we underclaim on purpose.

Real-fit checks

Fastener clearance against ISO 273 tables, part-to-part interference by boolean volume, wall thickness, overhang, printer envelope.

Assemblies that mate

Multi-part designs with per-part parameters and placements, pairwise interference-checked so parts fit before you build them.

Variants explorer

Sweep the design space, fully check every candidate, rank by weight, apply the winner as a new tracked version.

Real component library

NEMA 17, SG90, MG996R, 608ZZ, Raspberry Pi, Arduino, 2020 extrusion, exact datasheet dimensions injected so mounts fit the real part.

Systems & firmware

Wiring plans with power warnings, and firmware scaffolds that compile, generated to match the hardware they move.

Photo → plan

Show it a photo; Supra identifies the object and drafts the design intent, then asks for the measurements a photo can't give. Honest by design.

Version control for hardware

Commits, branches, releases, and engineering-aware diffs: Δ mass, Δ clearance, Δ check status. Not file bytes.

Self-improving

Every generation is archived; verified builds become learned examples; real-world build reports feed back in. Supra gets better from use.

Sandboxed & safe

AI-written geometry code executes in a locked container, no network, contained crashes, hard timeouts. The blast radius is zero.

Request early access

The pain we remove.

Hardware teams lose most of their calendar to hand-offs, rework, and unverifiable claims. Supra deletes the loop's dead time.

THE OLD WAY
WITH SUPRA
Weeks of CAD iteration for every revision
Parametric rebuilds from a sentence, in minutes
Simulation queued behind specialist backlogs
Loads, thermal, and flow checked on every change
Fit and clearance errors discovered at assembly
Interference caught before anything is cut
Tribal knowledge, no audit trail on decisions
Every claim on a signed verification ledger
Mechanical, electrical, and firmware in silos
One loop wires the harness to the exact geometry
DFM surprises when the factory quotes the part
Printability and machinability verified up front

Shipping today, on the record.

Not a roadmap. These run in Supra right now, every result labeled estimated or validated.

Structural sanity

Mesh cross-section bending and axial stress, safety factors against real material yield, deflection estimates on every load case.

Thermal margin

Steady-state hot-spot estimates with conduction plus convection paths, checked against material service limits.

Motion sanity

Mechanism degree-of-freedom analysis and travel interference hints before anything is printed.

Trade studies

Latin hypercube sweeps, Pareto fronts, and parameter sensitivity with a knee-point recommendation.

Release packages

BOM, revision notes, assembly sequence, compliance checklist, and sha256-stamped artifacts in one call.

Merge gates

Pull requests for hardware: a design with failing checks cannot merge, and the gate shows its evidence.

Lives inside real CAD.

Supra isn't a walled garden. It works with the open CAD stack you already trust, both directions.

WORKBENCH

A copilot panel inside FreeCAD

Type intent in a dock panel; parts and placed assemblies appear in your active document as real solids. Edit dimensions in the panel, the model rebuilds in place, fully re-checked.

TWO-WAY

Round-trip your edits

One click opens any part in FreeCAD. Push and pull with mature CAD tools, export STEP, import it back, Supra tracks it as a new version with an engineering diff against the original.

OPEN FORMATS

STEP-first, always

Exact BREP geometry any engineer can open, plus STL for the printer. Your designs are never trapped in a proprietary blob.

Five layers. One workspace.

Not a chatbot in CAD. Not a prompt-to-mesh toy. A coordinated engineering system.

L1

Build

Prompt-to-parametric parts and assemblies. Templates, standard components, dimension-aware edits.

L2

Check

Printability, fit and clearance, assembly sanity, structural and thermal estimates, honestly labeled.

L3

Release

Manufacturing exports, BOMs, build guidance, revision notes. A design state you can hand off.

L4

Systems

Motion sanity, actuator mapping, wiring guidance, firmware scaffolds, for products that move.

L5

Collaboration

Commits, branches, reviews, releases, plus publish, fork, and remix for the community.

Review hardware like code.

Branch a design into lighter, cheaper, stronger. Diff it in engineering terms, mass, clearance, printability, margin, not file bytes. Gate the merge on checks.

What we won't pretend.

Credibility is the product. Supra is engineered to underclaim.

SUPRA DOES

  • Exact geometry, exact clearances, exact interference volumes
  • Honest heuristics for printability, labeled as heuristics
  • Auto-fixes that are re-verified, never assumed
  • A ledger of every assumption and open risk

SUPRA WON'T

  • Claim simulation truth it hasn't earned, estimates are labeled estimates
  • Replace physical testing, it tells you which test to run first
  • Ship silent failures, every error is loud, logged, and on the record
  • Take the human out of safety-critical decisions

From first build to funded fleet.

These are illustrative scenarios written from our target workflows, not real customer quotes. Yet. Early access is how that changes.

“I built something real, and I barely knew CAD.”
