I built a macOS app on a 9 hour flight which renames your Downloads folder full of junk

I built a macOS app on a 9½ hour flight after work because I was tired of files named "Screenshot 2026-07-18 at 5.02.14 PM.png"

My desktop had become a graveyard of "IMG_3461.png" and "Untitled document (17).txt." I knew none of them. Opening each one just to rename it was a chore I was never actually going to do.

So I stopped renaming files by hand and built something that would.

Waypost reads what's actually inside a file (text, scans, PDFs, images) and gives it a name that makes sense, sorts it into the right folder, and tags it. All using Apple Intelligence, running entirely on your Mac. No cloud, no upload. Your lease agreement, your tax docs, your half finished essay: none of it ever leaves your machine. Turn off WiFi and watch it keep working.

Trust was the harder problem than renaming ever was. So I built in the controls I'd actually want: a toggle for every file type, naming conventions, folder-specific configuration, and an ask before renaming mode that suggests a name and waits for your click before touching anything.

Swift for macOS. Next.js on Vercel for auth. Stripe for payments. $7, once, no subscription, because there's no server to keep paying for.
