The world's first agentic engineer

What do you want to build?

Impulse is an agent-first IDE for physical engineering — like a tireless senior engineer at your side. Describe a part, a mechanism, or a whole product, then build it together in real time: it asks the right questions, reasons out loud, and reshapes real parametric CAD as you go. Yours to export anywhere — no CAD skills required.

See it work

You don't prompt for a file. You build it together.

This isn't one-shot CAD generation. It's an agent you design alongside — it reasons out loud, proposes the build, and reshapes real parts as you react, turn after turn. Like pairing with a really sharp engineer who never gets tired of your next idea.

Describe it, or show it

Give it any context. It scopes the whole product like a senior engineer.

Drop in anything — a photo, a sketch, a PDF datasheet, a STEP file, a screenshot, even a napkin drawing. Impulse reads it all, figures out the parts the product actually needs, lays out a plan, and drafts the whole thing — the way a real product engineer scopes a build before touching CAD.

  • Photos, sketches, datasheets & STEP files in
  • A complete bill of parts, planned for you
  • A working first draft in minutes
impulse — understands live

It thinks in geometry

Watch it reason about your design the way an engineer would.

Impulse holds a living parametric model of the entire product and reasons over it — fits, clearances, trade-offs, intent. Every move comes with rationale you can read and steer, not a black box that spits out a shape and hopes.

  • A living parametric tree of the whole product
  • Transparent engineering rationale
  • Decisions you can interrogate and redirect
impulse — reasons live

Real parts. Total control.

Every part and feature is real — and you can change anything by asking.

These aren't frozen meshes. They're real parametric parts and features in a live canvas. Tell it to hollow out a bowl, move a mount, or thicken a wall and it reshapes the actual geometry in place — no remodeling from scratch.

  • Editable parts and features, not static meshes
  • Conversational control over real geometry
  • Change one thing without breaking the rest
impulse — control live

Yours to take anywhere

Export clean CAD and finish it in SolidWorks, Onshape — wherever you work.

Impulse speaks the formats the manufacturing world runs on. Export a real STEP file and keep going in SolidWorks, Onshape, or Fusion — or send it straight to your printer or shop. No lock-in, no dead ends.

  • Real STEP, not a throwaway mesh
  • Opens cleanly in any professional CAD tool
  • Print it, machine it, or keep refining it
impulse — export live

Not just parts

Describe a product. It invents the whole thing.

Anyone can hand you a single bracket. Impulse composes complete products — it works out every piece the product needs and sizes each one to fit the others: the mechanism, the mounts, the electronics bay, and the way it all goes together.

The request

A smart automatic dog feeder — holds about 3 days of kibble, dispenses a set portion on a schedule, runs on an ESP32.

ImpulseComposed seven parts that fit together — a hopper, an auger and motor mount, a portion wheel, a chute, a removable bowl tray, an electronics bay, and a snap-fit housing.

A part is a shape. A product is dozens of parts that have to agree with each other — sizes, clearances, mounting, assembly order. Impulse holds the whole thing at once, so what comes out actually goes together.

How it works

Like working with an engineer. Because it works like one.

Impulse doesn't guess a shape and hope. It plans the design, asks what it needs to know, builds it step by step in front of you, and verifies the result before calling anything done.

01

Reads your intent

“A bracket that holds my camera over the workbench.” Pulls out the constraints worth asking about.

02

Asks what matters

Camera weight? Desk thickness? Tilt range? It gathers what an engineer would before drawing a line.

03

Builds with real operations

Sketch → extrude → holes → fillet on a professional CAD engine. Not a generated mesh.

04

Measures what it built

Holes open on both faces. Mating surfaces touch. 40.0mm where you asked for 40.

05

Designs for how it's made

Checks it can actually be manufactured — wall thickness, draft, overhangs, clearances — for your printer, your process, your material.

06

Hands you the files

STEP and STL, ready for your printer tonight or the shop tomorrow.

op: parse intent

Why it's different

This isn't text-to-CAD. It's an engineer you build with.

Most “AI CAD” takes one prompt and hands back a file — a mesh you can't edit, or a script you can't talk to. Impulse is agent-first: give it any context, answer the questions it asks, and develop the product together in real, professional CAD — turn after turn.

It's a conversation, not a prompt box

Impulse asks the questions a real engineer would — load, clearances, tolerances, what it mounts to — then builds with you, reasoning out loud and reshaping real geometry as you react. Turn after turn, never one-and-done.

Feed it anything; it gets the context

Photos, sketches, PDF datasheets, STEP files, a screenshot, a napkin drawing — drop it in and Impulse grounds the design in your actual parts, dimensions, and constraints.

It understands the product, not just a script

Impulse holds a living semantic + spatial model of the whole build. Talk to any part by name — “thin the bowl wall,” “add a second mount,” “mesh these gears” — and it knows exactly what you mean.

It designs for how you'll make it

This is the part that saves you the failed prints: Impulse checks the design can actually be manufactured — wall thickness, draft, overhangs, clearances and tolerances — tuned to your process, whether it's a 3D printer, CNC, or injection mold. Manufacturable when it lands, not after three reprints.

Real engineering — yours to take anywhere

Every move is a true CAD operation on a professional kernel: sketches, cuts, gears, fillets, assemblies, exact dimensions. Export clean STEP and finish in SolidWorks, Onshape, or Fusion. No meshes, no lock-in.

From a real session

Make the bowl removable and hollow it out to save material.

ImpulseDone. The bowl now lifts free of the tray, and I shelled it to a 2mm wall — solid where it seats so it still sits flush.
Bowl detaches cleanly from the tray
2.0mm wall — about 38% less material

Give me two ways to mount the motor.

ImpulseHere are two — a screw-down bracket and a snap-in cradle. Both line up with the auger. Pick one and I'll wire it into the assembly.
Option A — screw-down bracket, M3
Option B — tool-free snap-in cradle

Who it's for

One IDE for everyone who builds real things

Inventors & product teams

Design the system →
Engineering teams

The boring 80%, done with receipts.

Jigs, fixtures, brackets, rev N+1 — an agent that documents every decision, measures what it built, and hands back clean STEP. STEP in, STEP out.

Offload the grind →
Studios & agencies

Whole product lines, client-ready.

Spin up variants, explore directions alongside the agent, and export real CAD your clients' engineers can pick up and run with — no lock-in.
