Linky AI is a consumer AI companion app that lets users chat and roleplay with a large library of virtual characters or design their own. Companions can be customized by gender, personality traits, voice, background story and visual style, including 2D, Live2D, pixel and 3D presentations. The app supports voice calls, multilingual conversation and a collectible character-card mechanic similar to other entertainment-focused chat apps. Linky positions itself as a fun, SFW way to interact with AI personalities and is available on iOS and Android with a freemium model: the basic app is free and subscription plans unlock premium features and content. The product is run by an app studio (operating under the Linky/linke.ai brand) and has grown a sizable catalog of community-created characters.
