Stephen Fonseca has spent the last four years testing AI companion apps the way he once tested dating platforms: using them daily, paying for the subscriptions himself, and tracking what actually changes after the free trial ends. He writes the majority of Aigirlmates' hands-on reviews and comparison guides — AI girlfriend and boyfriend apps, NSFW image and video generators, voice and roleplay chat, and the privacy trade-offs most product pages leave out. His testing routine is deliberately unglamorous: the same set of prompts across every app, a check on billing descriptors and data-deletion policies, and a re-test whenever a major model update ships.
