Antika Circuit

Antika Circuit is an AI circuit simulator that lets you design, simulate, and understand electronic circuits in the browser, aimed at students learning hardware and engineers prototyping. You describe what you want to build in plain language and its AI agent generates a complete circuit you can then edit and simulate in real time, watching voltages, currents, and transients update on the canvas as you change a source voltage or resistance. The homepage demonstrates a SPICE-lite transient solver running at 60fps in the browser with no install and no credit card, so you can see a capacitor charge live as you move a slider. Beyond the AI tutor — which builds a circuit from a prompt, edits an existing one, and finds and fixes a short while explaining the reasoning — Antika Circuit lets you move between schematic, breadboard, and 3D views, collaborate live with shared cursors and presence like Figma, and export designs to SPICE or KiCad. As an AI circuit simulator, it targets the gap between intimidating desktop CAD and a first LED, making it a fit for learners and hobbyist-to-professional prototyping. The Student plan is free, and Product Hunt users get 30% off Pro for three months.

Best for electronics students and hobbyist-to-pro engineers who want to design, simulate, and export circuits in the browser with an AI tutor.
