It's software that you run, on your hardware. Currently there's a desktop installer for win/mac/linux (so people can try it out easily on their laptop or whatever), but I'm building a multiarch Docker image that runs on a droplet/ec2 micro/NAS/raspberry pi.

I run it for my family off of a rpi 4 sitting in an external 10tb USB drive, plugged into my router.

The external drive gets grabbed in case of fire/earthquake, but also gets backed up to backblaze for offsite backup.

> How is this not just "dropbox, but only for photos"?

Dropbox is a file synchronization service.

* You view your files by folder

* Files can only live in one folder

* There's no automatic organization of your files

PhotoStructure is designed to make browsing millions of photos and videos fun and easy, and effortless.

* Best-of-class metadata extraction and inference

* Automatic organization and tagging of your photos and videos based on that metadata

* Hierarchical tagging, with random "tastes" of what's in that tag (or child tags)

* Automatic, best-of-class "asset variation" merging (so when you have a RAW and JPEG version of an image, along with a Apple Photos resized preview, and a Google Photos takeout, they all are considered to be variants of the same asset).

* Cross-platform, cross-file-system support (so if you plug in an external hard drive and it automatically mounts to a different path, the files on that volume are considered equivalent).

* All viewed through a webapp and image delivery system that's built to be delightful and responsive even on low-powered servers and low-powered mobile devices
