I made a platform where you can create and publish adventures to play like an rpg. It has a creator page, and if you login, you can save and publish your adventures to the main page.
It runs on GPT3.5, Whisper for speech to text, the in-built browser text to speech (play on chrome for best audio), and Stable Diffusion 2.1 for images.
It's free! Let me know what you think!
