Question: Is there a platform that allows me to create custom AI characters for chat interactions during my streams?

If you want a platform to build your own AI characters for chat interactions in your streams, Tangia is a good option. Tangia has a number of features, including Custom AI TTS for custom voice interactions, AI Conversations for spontaneous chat with AI characters, and a big library of memes and interactions. It also can generate images, soundbites and supports multiple platforms including Twitch and YouTube, so it's a good all-purpose tool for streamers.

Another option is Inworld Arcade, which lets you chat with AI characters with voice or text messages. It's got a variety of characters, including ones you can create yourself and famous people, and lets developers create and share their own AI characters. It's good for interactive storytelling or just hanging out with AI personas.

DreamPal is also notable for its customizable, intelligent virtual companions. You can create your own DreamPals by uploading an image and defining personality traits, and you can chat with them by voice, text message and image request. The AI is trained on your feedback, so interactions become more personalized over time, and it's got a roleplay mode that can be a fun way to spice up your streams.

If you want something more sophisticated and flexible, Cypher is a conversational AI platform that lets you build and chat with your own AI characters in real time. It uses generative models for natural-sounding conversations and integrates with Discord and Telegram chat services for a direct and interactive way to chat with your audience.
