You're about to pay $300 for a $7 part.

There's a particular kind of helplessness that lives under a kitchen sink. You're folded into the cabinet, flashlight in your teeth, watching a slow bead of water track down a pipe you can't name.

There's a part down there that's the problem. You don't know which one. You don't know what it's called, which way it unscrews, or whether the thing you're about to loosen is the thing that sends water across the floor.

Until now you had two options, and both were bad. Option one: the YouTube rabbit hole. Forty minutes of a stranger's garage, a video shot for a faucet that's almost but not quite yours, a comment section arguing about cartridges. Option two: the $200 callout. You book it for next Tuesday, take the morning off, wait inside the four-hour window. Then a man kneels where you knelt, turns one screw a quarter-turn, and the drip stops. Ninety seconds of actual work. He writes the invoice on your counter while you do the math on what that screw just cost.

SokoJin is the third option. You take one photo of the mess in front of you. A few seconds later, the broken thing has a name, the right part is circled on your own image, and you get a short, visual, step-by-step path through the fix. Not a video of someone else's faucet. Yours.

The part that matters when it's your house

Here's what makes this different from a confident chatbot: when Jin isn't sure, Jin says so. It would rather admit it's unsure than hand you a beautiful, confident, wrong answer that sends you to the wrong part with dirty hands.

And it flat-out refuses the dangerous stuff, gas lines, live electrical panels, anything that can actually hurt you, and sends you straight to a licensed pro instead. An honest repair helper isn't the one that always has an answer. It's the one that knows when it doesn't.

Bytes to atoms. The only thing that counts is whether the thing in front of you actually works again when you're done.
