What is Quilter?
PCB placement and routing automated with physics-driven AI.
Who is Quilter best for?
Quilter is best for electrical engineers and hardware teams who want circuit board placement and routing done by AI.
Hardware teams short on layout staff
It lays out several boards in parallel overnight, so a design backlog clears without hiring another layout engineer.
Test, evaluation and validation boards
Quilter targets test fixtures, IC evaluation boards, design validation boards and backplanes, where speed matters more than hand-tuned routing.
Engineers who stay in their own CAD tool
You upload from and download back to Altium, Cadence Allegro, Siemens Xpedition or KiCad, with no proprietary file format.
Students and hobbyists
The Free Tier covers personal and academic projects with unlimited iterations and no time limit.
How much does Quilter cost?
Quilter is free for personal, academic and small-team use, while commercial teams pay per board project, priced by the number of pins left to route and quoted by sales.
- Unlimited design iterations and every Quilter feature
- Personal, academic and eligible professional use
- For teams under 10 people and $50K a year in revenue
Enterprise, for commercial use, has no seats or yearly licence: each board project is priced by the unrouted pins at upload, and sales gives the quote. A project includes unlimited iterations, parallel jobs, guided onboarding on your first board and output for Altium, Cadence Allegro, Siemens Xpedition or KiCad, and the bill of materials can change by up to 10% before it counts as a new project. Running Quilter in your own cloud costs more than the managed cloud. Funded hardware startups can apply for a discounted startup program. On the Free Tier, Quilter may use board metadata to train its engine; Enterprise designs are never used for training. Full pricing on quilter.ai. We checked these prices on .

Where can I try Quilter?
On its official website, quilter.ai.
How does Quilter count a project for pricing?
Quilter prices each board by the pins still unrouted when you upload it, so pins you route yourself first are not charged. You can iterate on a project as often as you like, and it stays one project while the bill of materials changes by 10% or less.
