Today, we’re excited to share the preview of AI Auto-Layout, powered by Flux Copilot. This is the next step toward full layout automation. With just one click, Copilot tackles the repetitive task of routing your board, delivering clean, human-like results that are easy to work with and iterate on. Whether you're working on a simple or moderately complex design, AI Auto-Layout helps you stay in the flow while saving hours of effort.
Since this is a preview release, we’re rolling it out gradually and collecting feedback to make it even better. Not everyone will see it immediately, but if you’re one of the lucky early users, we’d love to hear your thoughts. Want to try it out? Simply login to see whether you have access or apply to our early access program.

One of the biggest challenges with traditional autorouters is the complexity of setup. By the time you’ve configured everything, you might have already routed the board manually. AI Auto-Layout eliminates this frustration by providing a streamlined, fully integrated experience with smart defaults that’s easy to use for beginners while remaining powerful and customizable for advanced users.
For simple and medium-complexity boards, the smart defaults handle most configurations for you, so all you need to do is finalize your schematic, place your components, and hit “Auto-Layout.” The smart defaults for trace width and spacing are intelligently applied, allowing you to focus on design, not setup.
If you need more control, advanced customization is only a few clicks away. Add keep-outs, define custom trace widths, and set advanced constraints to meet specific design requirements. Learn more about how to setup your project by watching this video tutorial or reading the documentation on AI Auto-Layout.
Iterating with AI Auto-Layout is also seamless. Feel free to route part of your board with critical, or high speed traces, and then allow AI Auto-Layout to complete the busy work. Whether you’re relying on defaults or customizing advanced constraints, AI Auto-Layout starts routing with just a single click.
This combination of simplicity and flexibility makes AI Auto-Layout accessible to anyone, from beginners building their first PCB to professionals designing for production. It’s routing that adapts to your needs, not the other way around.
Traditional autorouters often treat routing as a purely mathematical exercise, optimizing only for shortest paths without considering practical realities like manufacturability, signal integrity, and clarity. The result is all too familiar: tangled, robotic layouts that are tough to debug and frustrating to iterate on.
Flux’s Auto-Layout takes a completely different approach. By using advanced AI techniques—especially Reinforcement Learning (RL)—it finds routes that feel intuitive and professional. Instead of following rigid, one-size-fits-all rules, RL allows the AI to continuously adjust its decisions. It learns from each choice, honing in on cleaner, more balanced arrangements that reflect real-world design priorities.
As Auto-Layout runs, you can watch the layout improve over multiple iterations and accept or cancel at any point. Simple boards might converge on a good solution in a matter of minutes, while more complex projects may require longer—sometimes 10-15 minutes or even several hours. The result is a PCB layout that’s easier to understand, refine, and trust.
Examples of AI Auto-Layout’s Human-like Results:
Sensitive Power Trace Prioritization: Auto-Layout identifies critical power traces and prioritizes them for optimal routing, preserving signal integrity and minimizing interference.
Crystal Oscillator Signal Routing: Auto-Layout ensures crystal oscillator signals take the shortest path to the clock input, reducing degradation and interference, while maintaining safe distances from other nets.
Throughout this process, your data remains yours. We employ robust encryption and modern data centers to keep your information secure, just like the trusted cloud services you rely on daily. If you want to learn more, please take a look at our Privacy Statement.
We’re thrilled to introduce AI Auto-Layout as part of a preview release, with access rolling out gradually. If you’re a new user, you’ll have free Copilot credits included in your 2-week trial, which you can use to explore the feature if you’re granted access. For paid users, AI Auto-Layout uses the Copilot credits already included in your plan. Need more credits? Visit Plans & Payments to keep your projects on track.

As this is a preview release, your feedback is essential to helping us refine and improve AI Auto-Layout. Join us on this journey to make PCB design smarter, faster, and more intuitive for everyone.
The Raspberry Pi Zero 2 W is a small and powerful computer with impressive performance for its size and price. With a quad-core processor, 512MB of RAM, built-in wireless connectivity, and a USB On-The-Go port, it's suitable for many projects, including home automation, media centers, and robotics.
We're excited to reveal a major upgrade - Flux Copilot is transitioning from being a helpful guide to a proactive partner. It no longer just advises but, with your approval, can now wires components together! This is a small step towards fully generative AI, reducing the time and complexity often associated with component connections.
Integrating AI into hardware development just became easier. Improve your research and planning phase with Flux Copilot—no need to change your existing tools.
KiCad revolutionized PCB design by making it accessible to everyone. Flux builds on that foundation, offering a browser-based, AI-powered platform that takes your PCB design experience to the next level.
For months, we’ve been adding new features and functions to Copilot to help make it the most powerful AI for hardware design in the world. Today, we’re announcing what might be the biggest upgrade yet: Copilot Vision.
With Flux, enterprises can take their architectural ideas and use AI to transform those ideas into actionable items. With Copilot, your enterprise can generate schematics, perform AI design reviews, and even identify PCB technology, budgets, and timelines well in advance of any manufacturing.
Imagine blending the intricate world of circuitry with the serene beauty of nature. That's exactly what I've done with Flux’s first collection of wallpapers, designed exclusively for the innovators of our world.
We’re incredibly excited to announce that we have decided to open up Flux and move out of private beta! What does this mean? If you’re a current user of Flux - nothing will change for you. For new users, this means that we’re now allowing anyone and their team to signup!
