The world's first agentic engineer
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.

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
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.
It thinks in geometry
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.
Real parts. Total control.
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.
Yours to take anywhere
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.
Not just parts
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.
What it composed
Desktop air-quality monitor
“a desk air monitor around a PMS5003 and a small OLED.”
Automatic plant waterer
“water four plants from one tank on a timer.”
Pour-over coffee station
“a stand that fits my 02 dripper and my scale.”
FPV drone — full build
“a 5-inch quad around my flight stack.”
Planetary gearbox
“a 20:1 reducer for a NEMA-17, meshing gears.”
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
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.
Reads your intent
“A bracket that holds my camera over the workbench.” Pulls out the constraints worth asking about.
Asks what matters
Camera weight? Desk thickness? Tilt range? It gathers what an engineer would before drawing a line.
Builds with real operations
Sketch → extrude → holes → fillet on a professional CAD engine. Not a generated mesh.
Measures what it built
Holes open on both faces. Mating surfaces touch. 40.0mm where you asked for 40.
Designs for how it's made
Checks it can actually be manufactured — wall thickness, draft, overhangs, clearances — for your printer, your process, your material.
Hands you the files
STEP and STL, ready for your printer tonight or the shop tomorrow.
Why it's different
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.
Give me two ways to mount the motor.
Who it's for
Go from idea to a complete product.
Describe what you're building and iterate on the whole thing — every part sized to fit the others, the assembly held together as you change your mind.
Start building →Gears, mechanisms, mounts, and enclosures that fit.
Meshing gear trains, linkages, and moving assemblies — built around your boards, motors, and actuators, with standoffs on your holes and cutouts on your ports.
Design the system →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 →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.
