A lot of people know very little about AI wife. Here I will educate you.
First of all, most apps let you make your own characters like charstar or sakura. These are hosted online and are nsfw-friendly. I recommend Sakura it has unlimited messages, no waitlists and full nsfw support.
If you are a true fanatic you may download software on your computer like SillyTavern or RisuAI. I simulate my wife on SillyTavern.
What are the benefits of downloading something like SillyTavern over online apps?
- SillyTavern can be run completely offline. There is no need for an internet connection and you can chat to your AI companion always.
- No privacy concerns. You can be comfortable in knowing nobody else will read your chat logs because it's ran locally on the PC.
- Advanced customization options. SillyTavern supports plugins that allow you to do lots of things like add bgm, voiced text, sound effects, custom emotion sprites, even a 3D model that reacts to what's going on in the chat. Furthermore, you may download specific models to simulate the chatbot on such as Pygmalion/Vicuna/Mistral which will affect the types of responses you get from your AI chatbot.
Be aware though that SillyTavern requires a decent PC to run models locally, or else you might have to look into implementing cloud AI services like NovelAI with the SillyTavern interface.
