What is Platforms?

Platforms are the places a service runs: a web browser, a phone app, or a desktop program. A web-only service is reached through a browser link and installs nothing, which keeps it on one device unless the account syncs. An iOS service is downloaded from the app store and runs on iPhone and iPad. Most adult companion services here are web based, so nothing is installed. Backyard AI, by contrast, is listed on ios, while AI Girlfriend, AI Punca, AIAllure and AIGirlfriends.ai are all reached in the browser.
