GhostWire

GhostWire is an Augmented Reality debugging tool for Tinkercad Circuits powered by Google Gemini Flash / any api model you have. It captures the circuit image, analyzes it for wiring errors (such as backward LEDs or missing grounds), and overlays the correct wiring path directly on the browser canvas using a neon green indicator.

Features

• Real-time Analysis: Captures the active browser tab to analyze breadboard circuits.
• AI Diagnostics: Uses Gemini 1.5 Flash to identify component polarity and connection logic.
• AR Overlay: Draws SVG lines and error messages directly over the Tinkercad interface to guide corrections.
• Example:
