State the objective.
Plain language, hard constraints. Nothing is built yet.
Plain language, hard constraints. Nothing is built yet.
The work decomposes into a parts manifest. Your constraints lock first.
Real CAD solids assemble part by part. Never a dead mesh.
Clearance, walls, fasteners, fit, interference. Obvious failures auto-fix.
Structural and thermal behavior, before anything is cut.
Wired to the exact hardware in the geometry.
The design space swept, every candidate fully checked.
STEP, STL, BOM, firmware, and the full verification ledger.

Try it
Every claim on this page is something you can move, toggle, and watch respond. No video, real geometry.
Stress, thermal, and airflow on the same bracket. Switch the analysis and read the result off the part.
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
Every design runs the gauntlet virtually: wind tunnel, loads, thermals, endurance, before a single part is made.
Electronics, end to end
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
Structure, envelope, mechanical systems and power, coordinated on one model. Switch systems and read each off the building.
CAD. Checks. DFM. BOM. Firmware. Docs.
Objective, constraints, what done looks like, in plain language, or from a photo of the thing you're building around.
Supra proposes the steps and asks only what's critical. Nothing builds until you say so.
Editable, parametric geometry, never a dead mesh. Sized to real components' datasheet dimensions.
Fit, clearance, printability, interference. Failures surface in seconds, the obvious ones fix themselves and get re-checked.
STEP, STL, BOM, firmware, build guide, revision notes. A design state you can hand to reality.
Point tools optimize one step. Supra owns the whole path, and every claim it makes is labeled estimated or validated.
Supra shows its full plan, constraints, assumptions, open questions, before a single feature is built. One-click approve or revise.
Prompt-to-parametric parts on a real BREP kernel. Editable dimensions with typed bounds, exact STEP + STL export. Never a dead mesh.
Every check records its method, measured value, assumptions, and residual risk. Trust through visibility, we underclaim on purpose.
Fastener clearance against ISO 273 tables, part-to-part interference by boolean volume, wall thickness, overhang, printer envelope.
Multi-part designs with per-part parameters and placements, pairwise interference-checked so parts fit before you build them.
Sweep the design space, fully check every candidate, rank by weight, apply the winner as a new tracked version.
NEMA 17, SG90, MG996R, 608ZZ, Raspberry Pi, Arduino, 2020 extrusion, exact datasheet dimensions injected so mounts fit the real part.
Wiring plans with power warnings, and firmware scaffolds that compile, generated to match the hardware they move.
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.
Commits, branches, releases, and engineering-aware diffs: Δ mass, Δ clearance, Δ check status. Not file bytes.
Every generation is archived; verified builds become learned examples; real-world build reports feed back in. Supra gets better from use.
AI-written geometry code executes in a locked container, no network, contained crashes, hard timeouts. The blast radius is zero.
Hardware teams lose most of their calendar to hand-offs, rework, and unverifiable claims. Supra deletes the loop's dead time.
Not a roadmap. These run in Supra right now, every result labeled estimated or validated.
Mesh cross-section bending and axial stress, safety factors against real material yield, deflection estimates on every load case.
Steady-state hot-spot estimates with conduction plus convection paths, checked against material service limits.
Mechanism degree-of-freedom analysis and travel interference hints before anything is printed.
Latin hypercube sweeps, Pareto fronts, and parameter sensitivity with a knee-point recommendation.
BOM, revision notes, assembly sequence, compliance checklist, and sha256-stamped artifacts in one call.
Pull requests for hardware: a design with failing checks cannot merge, and the gate shows its evidence.
Supra isn't a walled garden. It works with the open CAD stack you already trust, both directions.
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.
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.
Exact BREP geometry any engineer can open, plus STL for the printer. Your designs are never trapped in a proprietary blob.
Not a chatbot in CAD. Not a prompt-to-mesh toy. A coordinated engineering system.
Prompt-to-parametric parts and assemblies. Templates, standard components, dimension-aware edits.
Printability, fit and clearance, assembly sanity, structural and thermal estimates, honestly labeled.
Manufacturing exports, BOMs, build guidance, revision notes. A design state you can hand off.
Motion sanity, actuator mapping, wiring guidance, firmware scaffolds, for products that move.
Commits, branches, reviews, releases, plus publish, fork, and remix for the community.
Branch a design into lighter, cheaper, stronger. Diff it in engineering terms, mass, clearance, printability, margin, not file bytes. Gate the merge on checks.
GITHUB, FOR MACHINES.
Credibility is the product. Supra is engineered to underclaim.
These are illustrative scenarios written from our target workflows, not real customer quotes. Yet. Early access is how that changes.
