Placed and routed for you
CELUS stops at the schematic. siliXon places and routes the board in the same flow.
The CELUS alternative that routes the board too
CELUS turns your requirements, a sketch or a block diagram into a schematic and a BOM built from validated circuit modules, which is genuinely useful. Then it politely hands you over to your EDA tool, where placement, routing and the fab package are still your job. siliXon does not stop at the schematic: from one plain-English description it picks the parts, draws the circuit, places and routes the board and exports Gerbers, drill files, a BOM and pick-and-place data.

Verdict
Choose siliXon to get a finished, routed board from one tool.
Choose CELUS to generate a schematic and BOM for your existing EDA workflow.
siliXon todaysiliXon is in early beta and builds two- and four-layer, mostly digital boards. Review every design before fabrication.
Where CELUS is strongerValidated circuit modules from manufacturer app notes, supply data on every part, sketch and image input, and handoff to professional EDA tools.
Time to a prototype
siliXon
5 to 20 minutes
CELUS
No PCB of its own
From an idea to a board you can send to a fab, on one scale from zero. Estimates for someone new to each tool.
What changes when you switch from CELUS
One tool, not two
No handoff to Altium, KiCad or Fusion to finish the layout. It all runs in the browser.
Fab files included
Export Gerbers, drill, BOM and pick-and-place data straight from siliXon.

So far creating my first project for 10 min - onboarding seems quite smooth
I like the self validation and how it explains everything too, makes it easier for me to quickly cross reference and learn on the go
Response is very meaningful, I like how it asks you questions to verify and gives you the options to choose the answers with the recommended on the one it thinks is a better option
Good so far. It is helpful and gives me advice
I have to say I love the UI and UX, the front end is really fun to interact with, with the little dynamic touches etc
Super helpful and easy to use
Really good actually better than Flux ai

Does CELUS lay out PCBs?
No. Its docs tell you to place, route and finish the layout in your EDA tool.
What does CELUS export?
A PDF report, CSV BOMs and a project package for Altium, Fusion/Eagle or KiCad, with footprints still to be placed.
Is CELUS free?
Community accounts are free, but their projects are public. Professional accounts are a paid annual subscription.
When does CELUS fit better?
When you already lay out in Altium, Cadence, Siemens or KiCad and want AI help up to the schematic and BOM.
