LoveB review
LoveB combines fictional companion chat with voice, images and video. Its public help center describes the companion builder, and the site puts a Gallery alongside Chat.
What you can set before the first chat
LoveB says you can choose a voice and personality when building a companion, as well as appearance options such as hairstyle. The help center also describes voice conversations and generated media. Its public navigation gives you separate places to chat and browse the gallery.
Deciding where your creations belong
Nastia AI says in its privacy policy that it has no public profiles, feeds or galleries. If you want to keep a single companion and your creations away from a public gallery, that policy makes the choice straightforward. LoveB’s gallery is part of the experience to weigh if browsing is something you want alongside chat.
Anabel’s take
I'd choose LoveB to build a character whose voice is part of the premise from the beginning. If I only wanted a place to write an ongoing conversation, I'd sooner give up the gallery and keep the experience contained.
