Flux walks you through the entire circuit board design process. Describe what you want to build, and AI handles the heavy lifting — researching components, generating schematics, placing parts, routing traces, and checking your design before you send it to a manufacturer. Here's how it works.
Describe
Tell Flux what you're building in plain language. AI asks clarifying questions, then generates a system architecture with component recommendations. Need a specific part? AI compares options side-by-side using real datasheet parameters so you choose the right components before a single trace is drawn.
Example: "Design a smart humidity sensor with WiFi and USB-C charging"
Design
AI places components and wires your schematic, including decoupling caps, pull-ups, and ferrite beads sourced from datasheets. Then switch to PCB view and launch AI Auto Layout: a reinforcement-learning model trained on professionally routed boards. Hand-route critical nets, let AI route the rest. First results in minutes.
Hand-route the critical 20%. AI routes the other 80%.
Manufacture
AI Review catches DRC violations like overlapping copper, floating traces, and missing ground fills before they reach the fab house. Export Gerbers, BOM, and pick-and-place files and order from any manufacturer.
Your files. Your manufacturer. No lock-in.
Every circuit board designer hits the same walls. Flux was built to knock them down.
$10K+/seat desktop software with separate tools for schematic, layout, and simulation. Manual file exports between steps. OS compatibility headaches.
How Flux solves it: One browser-based platform covers schematic capture, board layout, simulation, BOM generation, and Gerber export. No downloads, no license keys. Works on any device.
Overlapping copper, floating traces, missing ground fills. DRC violations are easy to create and tedious to track down.
How Flux solves it: Automated DRC runs continuously. Click any violation to jump to the problem. AI Review flags mistakes and suggests fixes before you export.
Finding the right part means cross-referencing datasheets, checking stock, and hoping your selection is still available at order time.
How Flux solves it: AI searches real inventory and datasheet data. Ask by spec ("low-noise op-amp, GBW > 10MHz") and get actual MPNs with availability. Out of stock? AI suggests drop-in replacements.
Traditional EDA tools have no real-time collaboration. Two engineers can't work on the same board at the same time. You email files back and forth, lose track of versions, and waste hours resolving conflicts.
How Flux solves it: Real-time multiplayer editing — like Google Docs for circuit board design. Multiple engineers on the same board simultaneously. Comment, review, and iterate with built-in version history.
Most EDA tools assume you already know what you're doing. No guided path from idea to board.
How Flux solves it: AI Copilot guides every stage. Describe what you want in plain language and it generates architectures, recommends components, wires schematics, and checks your work.
Routing is where circuit board design projects stall. Flux's AI Auto Layout is a reinforcement learning model trained on professionally routed boards, making intelligent decisions about trace separation, ground continuity, and signal integrity.
Flux AI handles part research, schematic generation, component placement, routing, and design rule checks. Describe what you want to build, and AI delivers a starting point you can refine.
Create and edit schematics with a full component library. Every change syncs instantly to your PCB layout, keeping your design consistent throughout.
Place components, define board outlines, and route traces with AI assistance. Flux supports multi-layer designs with impedance-aware routing and real-time DRC.
Design with real-time inventory, pricing, and alternate part suggestions. Your BOM is always sourced and ready to order.
Validate your design before manufacturing with built-in SPICE simulation. Test circuits, verify parameters, and catch issues early.
Work with your team in real time on the same schematic and layout. Built-in version control, comments, and role-based permissions keep everyone aligned.
Work with Flux.ai like an engineering intern: automating the grunt work, learning your standards, explaining its decisions, and checking in for feedback at key moments.

Loved by engineers pushing hardware design forward.
The process of creating a printed circuit board (PCB): selecting components, drawing schematics, laying out the board, routing traces, and exporting manufacturing files. Flux makes this accessible through AI-assisted design in your browser.
Traditional tools like Altium or Cadence cost $10K+/year. KiCad is free but complex. Flux is browser-based with no install and no license keys, combining schematic capture, layout, AI routing, and manufacturing export in one platform.
A simple board can be designed in hours; complex multi-layer boards take days or weeks. Flux's AI Copilot and Auto Layout significantly reduce design time.
Yes. Free tier for public projects. Paid plans start at $15/mo with a 14-day free trial. Students and educators get Pro for free.
Yes. KiCad on all plans; Altium and Cadence on Pro. For Altium, export in ASCII format. Binary exports will import empty.
Yes. Gerbers, BOM, and pick-and-place files compatible with any manufacturer. AI checks component availability before export.
Flux AI handles part research, schematic generation, component placement, route optimization, and design rule checks. It works best as a collaborator: it makes suggestions and explains its reasoning, and you make the final call. It accelerates your workflow but does not replace engineering judgment.
In-app chat with real engineers, documentation, YouTube tutorials, and a Slack community. Common issues like DRC violations and import problems are well-documented.
Automated DRC runs continuously, catching overlapping copper, floating traces, and ground fill issues. Click any violation to jump to it. AI Review adds a second layer before export.
Yes. Flux supports real-time collaboration with multiple engineers on the same schematic and layout simultaneously. Changes sync instantly, and version history tracks every edit.
