Reinforcement learning for designing electronics hardware that works.
PCB Layout in Hours, Not Months
Quilter is physics-driven AI that automates PCB placement and routing.
Trusted Industry Partners:
Go From Schematic to Board on Your Desk in a Fraction of the Time
Works With Your Existing Workflow
Upload Altium, Cadence, Siemens, or KiCAD projects directly. Define the board outline, pre-place connectors, determine the floorplan. You control the constraints.
Physics-Aware Design
Quilter identifies bypass capacitors, impedance-controlled nets, differential pairs, and other critical considerations for your review. You see exactly what Quilter will and won’t account for up front.
Iterate More
Try multiple stack-ups, multiple manufacturers, multiple form factors. All in parallel, in hours instead of weeks. Quilter makes layout fast and abundant.
Transparent Design Review
Quilter evaluates each layout against the full list of physical constraints provided. You get clear feedback on which design aspects are truly “done” and which need further review and improvement.
Seamless Board Handoff
Quilter returns files in the same format as you submitted. Run DRC, polish, generate fab files - all in the CAD tools you already use.
Manual Layout vs Layout Automation with Quilter
The layout work that professionals quoted at 428 hours took 38.5 hours of human cleanup with Quilter.

Why Teams Choose Quilter
Scale Without Hiring
Add boards, not headcount. Layout talent is scarce, and designs sit on hold waiting for it. Quilter runs multiple boards in parallel overnight, so the backlog clears with the team you have.
Compress Delivery Timelines
Boards that took 4 to 8 weeks now come back in days. Your firmware team stops waiting. Your validation starts sooner. Run 2 or 3 iterations in the time one used to take.
Validated AI for Hardware
Most enterprise AI pilots stall in proof of concept. Hardware teams in consumer electronics, aerospace, and defense are using Quilter to design boards reaching fabrication today.
Native Support for All Popular ECAD Formats

Quilter gives top PCB designers the superpower to turn weeks into days. It’s a complete paradigm shift. When you iterate faster, you can out-innovate your competitors.

“Anyone who's done circuit design long enough will be skeptical at first and assume this is just a fancy auto-router, because nobody who tried auto-routing ever liked it. But the way you approach placement overcomes a lot of those barriers, and makes this a genuinely useful tool that saves time.”
Principal Engineer, Defense and Aerospace
“The biggest value is efficiency. Producing a quick derivative of a core design takes a lot of effort. Quilter can let us serve customers much faster and reach far more of them than we could before.”

No Training on Your Data
Most AI tools are only as good as the data you feed them, which is why so many stall before they deliver value. Quilter learned layout by playing millions of synthetic boards against the laws of physics, the way AlphaGo learned Go. We don’t train on your data, and you get value on the first board, not after a large data cleanup project.
Compliant with Cybersecurity Best Practices
Data is encrypted at rest and in transit using security best practices (TLS1.3, AES-256), independently audited and compliant with industry standards. What SOC 2 Type II Means for Your Design Data ↗
Self-Hosted Deployment Available
We offer an option to deploy Quilter inside your own infrastructure. You control access, networking, and data residency while we manage the application.
Honest About What We Do Well
Quilter has a goldilocks zone today, and it's expanding with every release. Many teams adopt Quilter by running it end to end on the boards it handles well, and on the routine sections of more complex ones while they pre-route the critical parts themselves. Start today to build fluency on a tool that is evolving fast.
