Circuit Copilot is a free, no-login reference for students learning the silicon behind modern computing. This is the v0.1 — a small set of tools and a starter glossary — and a preview of a much larger platform in development.
Right now, Circuit Copilot is a reference site. Ten interactive calculators for the math every EE undergraduate needs daily, and a small glossary explaining the hardware concepts that most curricula skip — what's actually inside a GPU, what a process node really measures, why FPGAs and ASICs exist alongside GPUs, where the AI compute bottleneck really sits.
Everything is free. No login. No ads. No tracking pixels. The calculators run entirely in your browser — your inputs never leave your machine. The glossary entries are written to be read in under five minutes each. The PDF cheat sheet is yours for an email address, nothing more.
The reference is the starting point. The full platform — coming later — will be an interactive learning system for hardware: upload your circuit design as a netlist or schematic image, get real simulation results, get a Socratic AI tutor explaining what's working and what isn't, and progress through a graded curriculum from your first voltage divider to your first VLSI design.
It's being built for students in developing countries first — where access to good tutors, expensive simulation software, and rapid feedback has historically been hardest to come by. If that describes you, drop your email on the homepage and you'll be among the first invited when it's ready.
Every generation of engineers stands on the work of the previous one. The generation training transformers and deploying LLMs is, by and large, not the generation that learned how transistors and gates and ALUs actually work. That's not their fault — curricula didn't keep up, and the gap between "use an AI API" and "understand the chip it runs on" widened faster than anyone planned for.
This site is a small attempt to close that gap. Pick up a calculator when you need it. Read a glossary entry when you're curious. Sign up for the platform when you want to build something real on hardware you actually understand.
New calculators and glossary entries are added regularly. If there's something missing you'd love to see — a tool, a concept, a typo I missed — write to hello@circuitcopilot.com. I read every message.
