I made an app to create Spotify playlists from music festival posters
Hey HN, I'm Brett and I'm an iOS developer. LineupSupply uses Apple's Vision framework to read text from an image and then the Spotify API to create a playlist using that text. So if you provide a music festival poster, it will grab the artist names from the lineup and make a playlist for that music festival. Often when going to a music festival I want a playlist to listen to the artists that will be performing. I couldn't find any other service that automates this, so I made one myself.

In plain words
LineupSupply is an iOS app that extracts artist names from music festival poster images using Apple's Vision framework, then automatically creates Spotify playlists from those lineups. Users photograph a festival poster, and the app identifies the performers and builds a playlist for preview listening. The app is free with unlimited playlist creation, and offers optional in-app purchases for additional features like per-artist song limits and custom icons. Spotify login is required but Premium is not.

So if you provide a music festival poster, it will grab the artist names from the lineup and make a playlist for that music festival.

The app is free to create as many playlists as you want, but does have a one time in-app purchase of $1.99 to unlock additional features (control over how many songs per artist, custom app icons, etc). You do need to login with your Spotify account, but Spotify Premium isn't required. I made this app with SwiftUI and its available on iOS and iPadOS. You can technically download it on macOS too, but it's a port of the iPad app.

Hey HN, I've been working on https://pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results.
