InstaPreview is how InstaArch catches the corrections before the city does.

Here's how plan review usually goes. You spend weeks getting your drawings tight. You submit to the jurisdiction. Then you wait — three weeks, five weeks, sometimes longer — only to get a correction letter back full of red ink. A missing detail. A code reference the local amendment changed last year. An egress width that's a half-inch short. So you fix it, resubmit, and go right back to the end of the line. Another month gone. Another draw delayed. Another client asking why it's taking so long.

We lived that cycle for years as a working architecture and engineering firm. InstaArch stamps drawings across the country, and we kept seeing the same pattern: the corrections that blow up your timeline are almost never the complicated ones. They're the predictable ones — the issues a trained reviewer spots in minutes, if someone actually looks before you submit.

That's the entire idea behind InstaPreview.

It's algorithm-driven software, built on everything we know from stamping plans across the country. Upload your drawings and our AI checks them against the real code — and the real local amendments — for the jurisdiction you're building in, before they ever land on the city's desk. You see the corrections first. You fix them on your schedule instead of the reviewer's. And you walk into submission already knowing what's coming back.

Why InstaArch built this

• We're not a software company guessing at construction. InstaPreview was built by a licensed architecture and engineering firm — the algorithm is trained on the way real plan review actually works, not a theory of it.
• We stamp nationwide. We track how requirements shift from one jurisdiction to the next, because we have to — and that knowledge is baked into the software.
• We move fast and we tell you the truth. Same way we run InstaArch — no meter running while you sit in the dark.
• We've been on your side of the correction letter. Everything about InstaPreview was designed by people the slow way burned first.

Plan review is the one part of a project you can't control. InstaPreview is how you finally get ahead of it.
