They Built the ‘Cursor for Hardware.’ Now, Anthropic Wants In
A startup called Schematik raised a $4.6 million pre-seed this week to become what it calls the Cursor for hardware — a service where you describe what you want to make and it generates the code, wiring diagrams, component list, and assembly instructions to build it. The catch: Schematik's service only works with low-voltage circuits, 3V or 5V at most. Higher voltages, founder Samuel Beek told Wired, could cause fires or shocks. The constraint is deliberate, not a limitation.
Anthropic wants that same layer of infrastructure — the bridge between an AI model and a physical device. The company announced a Bluetooth API for makers this week, positioning itself as a platform for AI-connected physical devices. The reference design it posted on GitHub is a small chip-based desk pet that displays permission prompts and lets you approve or deny actions from the device — but it requires developer mode, is not an officially supported product, and has no voltage guardrails of any kind. Independent makers built this first anyway. Marc Vermeeren published a device called Clawy on GitHub before Anthropic officially supported the pattern.
Kyle Wiens, CEO of iFixit, has a frame for why the underlying work is hard. Sorting through thousands of compatible components, ensuring voltage and current compatibility, generating accurate Bills of Materials — that kind of work is, he told Wired, a super hard problem. It is also exactly the kind of tedious, high-stakes task where a bad choice wastes real money and a good one saves real time.
Schematik drew a line at 3V and called it a design principle. The fuse that blew during its own testing, as Wired reported, is the most honest data point in the whole situation — someone tried to push past the safe limits, and the constraint held. The question is whether Anthropic, and everyone else trying to build the bridge between AI and physical things, will draw that line too, or whether the independent maker community will keep blowing fuses to prove why it needed to be drawn.
