looked into it recently out of curiosity. Joi.com is a platform built around AI characters you can chat with. It's not just a single chatbot; it's a collection of AI personas with different backstories, personalities, and styles. You can browse through them, pick one that fits your mood, and have a conversation. Some are designed for casual chat, others for more creative roleplay. You can also create your own character from scratch, adjusting traits, appearance, and behaviour. I spent about half an hour testing it, and the dialogue was surprisingly fluid. It remembered context from earlier in the conversation, which made it feel more natural. Everything is encrypted, and it works on mobile. There are free options to start with. I'm not sure I'd use it regularly, but it's an interesting space to explore if you're curious about how far AI conversation has come. The link is https://joi.com/characters/roleplay-ai if you want to check it out.
