Venus AI is one of the best NSFW alternatives of ChatGPT that lets you create and interact with AI-generated characters, both safe for work (SFW) and not safe for work (NSFW).
The features of this platform include creating custom characters, supporting multiple languages, and smart chat customization.
Users can also customize their chat settings including the name, personality, dialogue, and behavior of the AI characters.
The platform offers a free trial with a limited number of messages. You can access Venus Ai from their website, and iOS/Android applications. In addition, you can also explore their quite active community.
