Wrench Board

WrenchBoard is an AI assistant for diagnosing faults on electronic circuit boards. Rather than writing software, it is aimed at repair technicians and hardware hobbyists with a dead board on the bench. The vendor says the agent reads the schematic, simulates the fault and then hands the user a diagnostic protocol to follow, so the person brings the board and the agent supplies the analysis. The product is in early access and is offered through a signup page at app.wrenchboard.cloud. The interface text is partly in French and partly in English. The vendor, RepairMind Ltd, states that diagnostics are provided for guidance only and do not engage its liability. The site also notes that WrenchBoard took second place in Anthropic's Built with Opus 4.7 event in April 2026. Pricing is usage based. A new account receives $2.50 of AI diagnostics free every month, and no card is required to sign up. The site does not publish what additional diagnostics cost beyond that monthly allowance, and the upgrade page shows the same signup form.
