Pinetta is/was in development but seems dead with only an alpha release. I am chasing this up on Matrix. edit: Apparently still, technically, active although progress has been slow
Pinry is a FOSS alternative, but not federated, that seems dormant. However, it works and is in Python, so someone could bolt an AP server to it, he says airily.
Let me give you an example. I search for leftist content. I somehow get served a British guy who does floor refinishing. It's fantastic. I also get people doing skits about working in a restaurant.
A good algorithm follows patterns in people's preferences, not patterns in the content.
I use(d) Pinterest to collect fan-dom stuff and wallpapers. Each board for a movie, series, anime or game.
Nowadays I just search for a wallpaper and hope it isn’t AI, download it and leave the platform again. There’s no use on actually using the platform for what its intended (pinning, saving and sharing). Almost anything you do gets flagged by their AI bot for “inappropriate, adult or violence”.
I mean, they flagged a plant as “adult” content and smiling Luffy face as “violence”. Oh I forgot, their platform is just one giant advertisement crap now. 3/4 of the screen will be taken up by a video/gif of an advertisement.
I use it heavily for images for TTRPGs. As a GM, I grab images of Monsters, NPC's, background images, maps. For the Star Wars RPGs, ships, NPCs, deckplans. I use TokenStamp to create the map tokens of those NPCs I found... It is a great resource fot that kind of thing. I think I have "saved" over 2000 images for use in games.
I've used mostly for Art references when I'm drawing because the image search is mostly accurate for my needs, but now it is filled with Ai slop without a clear way to filter content, so it has became unusable for the past 3 years or so.
I use it to find inspiration for projects where I only have a rough idea of what I would like to build/make. Usually it's enough to create a new board, enter a vague search term, add some things that seem fitting to your vague idea and then Pinterest does a really good job in suggesting things similar to the results you already added. It narrows down the search results by what you save.
Ahhh, it a good image recommendation algorithm? That might be why I never got what to do with it. I just saved things I found, I didn't search for new.
Idk about you but I use pinterest to find inspo for all kinds of things. For that to work, the posts need extensive hashtagging/indexing that goes beyond the occasional hashtag on Mastodon I think. In Pinterest, I really want their Algorithm to find the stuff I don't know yet I'm looking for. If that kind of search existed, we wouldn't need a specific Pinterest clone I guess - maybe a topic-board thing on Pixelfed would be enough if the indexing would be sufficient.
Apparently, Pinetta is still active. There is an alpha release but it seems like the devs were struggling with time limitations and getting the AP protocol right. It is in Python if anyone wants to take a look.
I never understood pinterest. I think a different interface for https://mastodon.art should get you most of the way there. Maybe @[email protected] has a suggestion.
