Power and regulators
Every IC supply pin on a sensible rail, regulators with input and output capacitors, rail voltages that make sense for the parts on them.

AI design review for your KiCad schematic and PCB
Drop in your KiCad project and get a review like a careful colleague would give it: power rails, decoupling, pull-ups, footprints, routing and your ERC/DRC results, triaged. Every finding names the parts and nets involved, so you can check it in seconds.
- One free review per account, no credit card

Read the review
The AI explores the design through tools (overview, components, nets, routing, check results) and records findings as it goes. Download the report as Markdown and keep it next to your project.
What the AI schematic and PCB review checks
Rule checks find violations of rules. A design review finds the things no rule describes. pcbai does both: it runs KiCad-equivalent checks first, then the AI reasons about the design.
Decoupling
Bypass capacitors next to each IC, bulk capacitance on each rail, and decoupling that sits on the wrong net.
Pins and pull-ups
Floating inputs, missing pull-ups on reset, enable, boot and I²C lines, outputs driving each other, unused pins left without intent.
Net hygiene
Single-pin nets, label typos that split a net in two (SDA vs SDA1), misnamed power symbols.
Parts and footprints
Values and footprints that disagree, polarized parts on the wrong footprint, missing footprints, DNP parts on critical paths.
PCB routing
Unrouted connections, power nets on thin tracks, small vias carrying current, schematic and board out of sync.
ERC and DRC triage
Hundreds of warnings grouped into the few that matter, with the benign ones explained, so you don't have to scroll.
What it couldn't check
The summary says what it couldn't verify (for example, ratings that need a datasheet), so you know where to look yourself.
Findings you can act on
Each finding has a severity, a short explanation and the references and nets involved. Errors are things that will likely stop the board from working. Warnings are risks worth fixing. Notes are suggestions and checks to finish by hand.
The review prefers a few well-evidenced findings over a long list of guesses. When it relies on general part knowledge (say, the typical dropout of an AMS1117), it says so and asks you to verify it.
Warningdecoupling
U3 (STM32G0) VDDA has no local decoupling
Pin 9 (VDDA) connects to +3V3 directly, and the only capacitors on +3V3 are C1/C2 at the regulator. ST recommends 1 µF + 100 nF at VDDA. Add them close to the pin.

Your design stays yours
Your KiCad files are read and parsed in your browser, in a web worker. They are not uploaded. During the review the model asks questions (one component, one net, the check results), and only those answers go to the model, which runs on Amazon Bedrock with EU routing. Nothing is stored after the review, and your design is not used to train models.
Built for engineers who stay in control
pcbai is a KiCad-native tool for small hardware teams and consultants. Your project stays plain KiCad files in git. The AI checks, explains and suggests, and every change stays your call. No prompt-to-board generation.
Frequently asked questions
Is the AI design review really free?
Yes. Every account gets one full AI review of a KiCad project, schematic and PCB, at no cost and without a credit card. Registration with an email address is required so that each person gets one free review.
Which KiCad versions are supported?
Projects from KiCad 6 through KiCad 10 (.kicad_pro, .kicad_sch, .kicad_pcb), including hierarchical sheets, buses and custom design rules (.kicad_dru).
Are my design files uploaded?
No. Your project is parsed in your browser. During the review the AI asks questions about the design, such as one component's pins or one net's connections, and only those answers are sent to the model. The files themselves are not uploaded or stored.
Which AI model reviews the design?
A Claude model from Anthropic, run on Amazon Bedrock with routing kept inside the EU. The model reads your design through tools that query a KiCad-exact model of the netlist and board.
What does the review check?
Supply connections and regulators, decoupling and bulk capacitance, floating inputs and missing pull-ups, label typos that split nets, value and footprint mismatches, unrouted connections, thin power tracks and small power vias, and a triage of the ERC, clearance and schematic/PCB parity results.
Does the AI change my design?
No. The review only reads the design and reports findings. You decide what to change, in KiCad or in the pcbai editor.
Does it replace KiCad's ERC and DRC?
No, it builds on them. pcbai runs ERC, copper clearance and schematic/PCB parity checks that match KiCad's results, and the AI triages them and looks for the design-level issues rule checks can't see.
