Hi everyone, I'm Stéphane. I have about 138,000 photos on Flickr, and at that size the website stops being a place you can work: changing a tag means opening photos one by one, and there's no way to see what's missing a title or a location.

So I built Photo Stream Assistant for myself, then put it on the Mac App Store. It does the things I needed:

- edit titles, tags, dates, privacy and location on hundreds of photos at once

- rename or merge a tag across the whole library in one step

- file photos into several albums at once, and send them to groups within each group's limits

- back the whole library up to a folder on the Mac

- see where views come from and which photos lead

- find untitled, untagged or unplaced photos, and photos in no album

It runs on your Mac and signs in with your own free Flickr API key (the app walks you through getting one). There's no account with me and no server in between. It's free to use, with a one-time Pro unlock for the bulk tools, no subscription. Eight languages, macOS 12 or later.

It's an independent app, not affiliated with Flickr or SmugMug. I'd love to hear what you'd want it to do next.
