Circuit design at thespeed of thought

Describe the board. The schematic draws itself, parts place themselves and copper routes itself. You approve, verify and order.

how it works

Words in. Boards out.

Six stages from a sentence to a board you can order, in one conversation, with no cockpit to learn. You decide at the start; the engines do the rest and measure what they did.

You describe, it plans. Brief it like an engineer: parts, functions, constraints. In review mode the plan waits for your approve, revise or reject.

Move the regulator next to its capacitors and reroute the power zone.

  1. Group the regulator with its input and output capacitors
  2. Recheck spacing against the JLCPCB rules
  3. Route copper, then run fabrication readiness

Walk through each step
what we hold to

Describe. Approve. Manufacture.

The model directs; deterministic engines draw, place and route. What reaches you is counted, not claimed.

  1. Describe

    You set the intent.

    Brief it in plain English. The agent answers with a plan in readable steps before it touches the board.

    The plan comes first

  2. Approve

    Nothing lands without your yes.

    In review mode every edit arrives as a draft. Apply it, revise it or throw it away.

    Drafts, never silent edits

  3. Manufacture

    What you approved is what ships.

    Gerbers, BOM, pick-and-place and KiCad are written from the same saved build you reviewed.

    One build behind every file

questions

Questions, answered.

Can AI really design a PCB end to end?
Yes: schematic, placement, routing, verification and manufacturing files, from a plain-English brief and your approvals. Deterministic engines do the layout and routing; the agent directs them and fixes what the checks find. Every result is measured: DRC, net counts, part coverage.
How is fluxboards different from other AI PCB design tools?
It does the whole job, start to finish, in one conversation: settling the spec, choosing real parts, the schematic, placement, routing, the checks and the files you order from. There is no cockpit of panels, layers and settings to learn first. You describe the board, approve the plan, and order; the bench runs the engines and shows you what it measured.
How does this fit my KiCad workflow?
One click exports a complete KiCad project (.kicad_sch, .kicad_pcb, .kicad_pro) with each part's 3D model. It opens directly in KiCad, with hierarchical sheets when the board uses them. Design here and finish there, or never leave.
Is the BOM really orderable at JLCPCB?
Yes. Parts resolve to real LCSC part numbers with live stock, each footprint is checked against JLCPCB's own, and pick-and-place rotations are corrected to match. A part that can't be sourced is flagged, never invented.
Do I need to learn prompting?
No. Describe the board, approve or revise the plan, and answer the occasional question with numbers. The bench checks every step against the engines, so a short brief still ends in a clean board.
Who owns my designs? Are my keys safe?
You own everything you design. Model keys are encrypted on our servers under your account, used only to call the provider you chose, and never shown back. Boards and chats of signed-in users are never used for training (guest chats run on a model whose provider may learn from them).
  1. Figures measured on a 4× OBD-CAN gateway board: 162 of 162 nets routed, 0 DRC errors.
  2. KiCad exports are re-read after export, so every part and net is confirmed present.
  3. Signed-in boards and chats are never used for training.
