Why this works
The problem: Large repair quotes often include high labor costs for jobs some owners could do themselves, but DIY mistakes can be dangerous.
How AI helps: AI can explain what the repair involves, estimate difficulty and tools, point you to parts sources, and tell you when to leave it to a professional.
