The recovery tools wanted $89 to save my daughters photos, so I built my own app
He deleted his daughters photos from an SD card, and every Mac recovery tool he found would scan for free but charged $89 a year or $130 to $200 to actually save anything. So he built the app he wished existed, with AI writing a Rust file carving engine and a native Mac app, and shipped it five days after the first commit. It is now a paid app of its own, $29 once, no subscription.

My agent sorts my Lightroom photos and quarantines the rejects against my NAS
He says he built a custom connector to Adobe Lightroom and has the AI organizing photos in it.

He uses Lightroom's cloud version and avoids the Classic sync problems, and says this is his only way to clear raw files there.

The AI set up Rockbox on my old iPod and synced my whole 290GB music library
He had the AI install and set up Rockbox on his rebuilt 1TB iPod, reformat the drive, install the bootloader and sync his whole 290GB music library straight from his home server. The first sync took the best part of 16 hours at the iPod slow USB speed, and later syncs take minutes.
