Stop starting from zero every time you build.

You forget what you tried last time. You can't find the file someone already made. You're debugging alone at 1am with no one to ask. Patch remembers your projects, the marketplace already has pieces other builders made, and you're never starting from a blank page again.

He'll remember this conversation tomorrow. Try him.

Tell him what you're building. Ask him something you'd normally Google. See what's different about talking to something that actually keeps up with you.

Three problems every maker has. One place that fixes them.

You lose context between sessions, you can't find work other people already did, and you're on your own when the code breaks. Here's how that changes.

Never re-explain yourself

Come back three weeks later and Patch still knows what you were building and why. No re-explaining your project from scratch, no digging through old notes.

Skip the part someone already solved

Someone's already built the STL file, the Arduino sketch, or the build guide you need. Find it, pull it into your folder, and start from where they left off instead of square one.

Never debug alone

Write your code right in the browser. When something breaks, Patch is already looking at it with you and tells you what actually went wrong, not just where.

Someone already put Patch to work. Here's what happened.

Triple C Price Tracker is a live site where collectors price out diecast cars. It doesn't have its own AI — it just asks Patch.

No more typing in every detail by hand

A collector snaps a photo of a Hot Wheels card. Patch reads the name, year, color, series, and brand off the packaging itself — nobody typed a thing.

Build the app, borrow the brain

The site's builder didn't have to train a vision model or write any AI code — they called the same Patch that remembers your conversations, over one API.

This could be your project next

Whatever you're building, on PatchOS or off it, can plug into this same brain for vision, memory, or reasoning — instead of building that from scratch.
