Shiuli: Alt Text that actually gets written. Most images online never get a description. Not because people don’t care about Accessibility, but because it takes time to look at a photo, think about what matters, and write it down. Shiuli makes that process easy. Get a clear alt-text description for any Photo. Simply select the photo, get an image description, change it to fit your needs, and copy it to use anywhere from Instagram, X, Threads, BlueSky, Mastodon, your Blog, Portfolio or CMS. Your image now has Alt - Text and is Accessible to everyone. Someone using a screen reader can understand it. The best part? You don’t even need to open the app! You can use Shortcuts, Visual Intelligence or our Action Extension to get Image Descriptions from anywhere.

Verdict
The clearest difference is price: PURPOSE Network at Free against Shiuli's $9.99. PURPOSE Network also leads on iOS requirement (15.1 vs 18.6). Shiuli's advantage is update cadence (every 3 weeks vs every 4 months) and chart position (#141 vs unranked). On ads and in-app purchases there is nothing between them.
