PCB Schematic Checker: LLM-powered tool to detect and catch PCB schematic design errors.

What it does

Traceformer is an AI-powered schematic checker that integrates with KiCad and Altium Designer. It analyzes PCB designs by pulling component datasheets automatically and checking schematics against those datasheets for design errors. The tool reports findings with specific datasheet page citations as evidence. Users can scope reviews to particular subsystems and see the cost of each review before running it.

Who it is for

The product targets both hobbyists and professional electronics engineers. The free tier is positioned for hobbyists and small-scale users. Starter and Team tiers serve individuals and small organizations building PCBs regularly. The Enterprise option is available for larger organizations with custom requirements.

Pricing

Free tier includes one review per month, up to 200 components and 10 datasheets. Starter costs $20 per month with $20 in monthly credits, up to 200 components and 20 datasheets per review. Team is $50 per seat per month with $50 in monthly credits per seat, supporting up to 1,000 components and 100 datasheets per review. Enterprise pricing is custom. An annual subscription saves 15 percent.

How it stands out

The tool explicitly avoids hallucinations by requiring all findings to reference specific datasheet pages. If the model cannot find supporting documentation, the issue goes into a "Missing Info" category rather than being reported as verified. This distinction lets engineers separate evidence-backed findings from items needing manual verification. The product also emphasizes that it operates alongside traditional electrical rule checking and design rule checking rather than replacing them. It focuses on datasheet and application-level validation, not simulation or basic connectivity rules.

What a founder should check

A rival builder should verify how entrenched the incumbent ECAD tools are in this workflow. KiCad and Altium users may already have integration with other AI or automation tools that could be extended instead. Second, examine switching costs carefully. Once a team adopts Traceformer and builds up review history or team processes, how sticky is the relationship, and does the per-review cost model create pricing pressure as volume grows. Third, investigate the moat around datasheet accuracy and model quality. If competitors can integrate datasheets just as effectively or train models on public component data, the differentiation narrows significantly.
