Pinproof reads your schematic and the datasheets for every part on it, then flags what breaks — wrong voltage ratings, reversed polarity, missing decoupling — before you send boards to fab. KiCad and Altium.
Export your netlist (.kicad_sch or an Altium export) and attach the PDF datasheets for the parts you're unsure about.
It extracts the limits straight from each datasheet and walks your netlist net by net — no pre-built rule library to maintain or trust blindly.
Every finding names the net, the pin, and the datasheet line it came from — so you can check it yourself in ten seconds.
This doesn't exist yet — there's no working tool behind this page, and no company behind it either, just one person checking whether it's worth building. A tool for this exact problem already ships commercially — Traceformer, from $20/mo per seat — which is the actual reason this is worth testing: the problem is real enough that someone already charges for it.
Pinproof's bet is different: instead of a pre-built rule library, the AI reads the datasheets you give it, for your parts, every time. Whether that's accurate and useful enough in practice is exactly what isn't verified yet.
Honestly — you can, and for a one-off check that might be enough. Here's where Pinproof actually earns its keep, concretely:
No manual export. Pinproof runs KiCad's own netlist exporter for you — every net, every pin, every footprint and LCSC reference — instead of you hand-copying values or screenshotting the schematic into a chat window.
A reviewer's checklist, not a blank chat. The prompt enforces one discipline most ad-hoc chats don't: cite the exact net, pin, and datasheet line for every claim, or say "can't verify" — never guess a voltage limit. Writing that into every conversation yourself, every time, gets old fast.
The context stays loaded. Upload once, then ask follow-ups — "what about C4", "check the whole analog rail" — without re-pasting datasheets each time or losing earlier context.
If you'd rather paste things into Claude yourself and write your own prompt, you probably don't need this product — and that's a fair call.
No manual review here — run it yourself. Start with 3 free reviews, no card needed. If it's useful, a one-time pack or a monthly subscription both work out far cheaper than the time a missed decoupling cap costs you at fab time.
One-time, never expires. Good for the occasional board.
