Grok's iOS app has introduced two new AI "Companions": Ani, an anime-style avatar with an NSFW mode, and Rudy, another fully animated character. These 3D avatars interact with users via voice. A third companion is labeled as "Coming soon," suggesting further expansion of the app's AI persona offerings. This addition aims to enhance user engagement through personalized, interactive experiences within the Grok ecosystem. The inclusion of an NSFW mode for Ani raises questions about content moderation and target audience.
