Describe the circuit in plain English ("I need a WiFi-enabled temperature sensor with battery monitoring"), and the AI generates the complete schematic: component choices, values, decoupling, pull-ups, ferrite beads, everything. Then edit it visually, collaborate in real time, and route the PCB without leaving the editor. Schematic capture becomes 10x faster.
Describe
Describe what you need in plain language. Flux’s AI selects real parts (with stock, price, and datasheets), builds the circuit architecture, and wires a complete schematic with the right passives.
Example: “Design a BLE beacon with an accelerometer and temperature sensor.” Flux returns a ready-to-edit schematic in seconds.
Refine and layout
Edit visually: swap parts, tweak values, add test points, and collaborate in real time. When you’re ready, generate the PCB with AI-assisted routing based on your design rules.
Hand-route the critical 20%. AI routes the other 80%.
Manufacture
Export Gerbers, drill files, and BOMs directly to JLCPCB, PCBWay, or Osh Park. Flux validates manufacturing constraints (panelization, layer stackup, via drilling) before you order. No surprises at fabrication.
Your files. Your manufacturer. No lock-in.
Schematic capture is a critical phase in hardware design. Here are common challenges engineers face, and how Flux approaches them differently.
Schematic wiring is detailed work. You place symbols, route wires, verify pin connections against datasheets, add decoupling capacitors, configure pull-ups and termination resistors, check for floating nets, and review for errors.
How Flux solves it: Describe the circuit, and the AI wires it. It adds passive components from datasheets and checks rules in real time.
Many EDA workflows use separate editors for schematic and layout. You build the schematic, export a netlist, open a layout tool, and sync changes between them. Some tools handle this sync well, others require more manual effort. Cross-tool workflows (like starting in KiCad and finishing in another tool) add an additional translation step.
How Flux solves it: Schematic and PCB layout in one unified workspace, always in sync.
Schematic capture relies on symbol libraries: every component variant needs a symbol with correct pin assignments. Most EDA tools have extensive libraries, and community-contributed libraries help fill gaps.
How Flux solves it: AI recommends components based on your circuit requirements, with real inventory and datasheet data.
Most schematic capture tools were designed for single-user workflows. Collaboration typically happens through file sharing, version control (like Git for KiCad), or cloud add-ons. These approaches work, but real-time simultaneous editing on the same schematic is still uncommon.
How Flux solves it: Multiple engineers edit the same schematic simultaneously with built-in version history.
Some platforms offer hybrid cloud/desktop workflows, combining desktop tools with cloud-based collaboration features. These work well for teams already invested in desktop EDA, though the experience can vary depending on which features live in the browser versus the desktop app.
How Flux solves it: Cloud-native real-time collaboration from day one.
Flux's AI Copilot uses reinforcement learning, trained on 10,000+ professionally routed boards from top hardware teams. Instead of manually routing every trace, you describe what matters (power integrity, signal timing, thermal zones) and the AI handles the repetitive work.
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.

Schematic capture is the process of drawing an electronic circuit using a CAD tool. Engineers use schematic capture software to place components (resistors, capacitors, integrated circuits), route connections (nets) between components, and document the circuit design. The output is typically a visual schematic diagram and a netlist, which feeds into PCB layout design.
Yes. Flux uses an AI hardware engineer that generates complete schematics from natural language descriptions. You describe what you're building ("WiFi module with battery monitoring"), and the AI selects appropriate components, wires the circuit, and adds passive components (decoupling caps, pull-ups, termination resistors) automatically. The result is an electrically correct, manufacturable schematic ready for refinement.
The best tool depends on your workflow. Altium, OrCAD, and KiCad are all excellent schematic capture tools with deep feature sets and strong communities. Flux takes a different approach: AI-generated schematics from natural language, a unified schematic + PCB workspace, and real-time collaboration. If AI-assisted design and browser-based workflows appeal to you, Flux is worth trying.
Yes. Flux imports KiCad files on all plans. Pro plan includes Altium and Cadence import. You can migrate existing designs into Flux, edit them with AI assistance, and export back to your original format if needed. No vendor lock-in.
Yes. Flux is browser-based with native real-time multiplayer collaboration. Multiple editors can work on the same schematic at the same time. Changes sync instantly. Conflicts are resolved automatically. Version history is built in, so you can revert changes or compare revisions.
Yes. Flux exports Gerbers, BOM, and pick-and-place files compatible with any manufacturer. You can also export as KiCad format.
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 direct support via help@flux.ai. Common issues like DRC violations and import problems are well-documented.
AI Auto Layout is used actively by 66-75% of Flux paying users, and they keep paying because it delivers real time savings. The AI is trained on thousands of professionally routed boards and uses reinforcement learning to optimize placement and routing. You can accept all suggestions, override specific ones, or turn it off entirely. It's a tool that respects your expertise while handling the repetitive work.
