We see Endless Visual Novel primarily as a game, not a writing tool. EndlessVN is easy to jump into and use right away, without having to play around with complicated settings and adjustments. However, you do have control over how the world and story will turn out. Thus, you could also think of EndlessVN as a tool for creating Choose-Your-Own-Adventure (CYOA) visual novels.

The underlying engine is playable but quite bare. We're constantly adding new features and tweaking things based on user feedback.

Text generation for EndlessVN uses GPT-J / GPT-NeoX. We will have additional larger models available in the future.

The sprites and backgrounds are generated using diffusion models like Stable Diffusion. In addition, the language models are utilized in prompting to generate characters and backgrounds that fit the specific story and setting. Players will eventually be able to regenerate and customize the characters and location backgrounds to their liking. It's also possible to use external, e.g. player made, assets to replace the generated ones.

We use a variety of neural nets to generate midi samples which will then be further post-processed to improve the quality. Initially the soundtrack for each playthrough/world is generated randomly, but you will have various ways of controlling it later on.

You can play right now by signing up at the top. Feel free to stop by our Discord community to share your feedback.

We have three subscription tiers: Free, Voyager and Creator. Players in the Free tier will be able to play a selection of public stories made by others. Players in the Voyager and Creator tiers can experience their own AI-generated adventures in worlds of their own creation. The pricing for these tiers will be adjusted during the development.

We use the highly secure encryption algorithm AES-256 to keep your stories secure while they are stored on our server. This means that even the NSA won't be able to read your stories, much less us.

Generated assets such as sprites and backgrounds are not encrypted, but they are not linked to your account in any way. In addition, we may collect anonymized snippets and additional metadata while you are playing to help us improve the AI. This additional metadata is aggregated and none of it can be linked to your account.

EndlessVN is developed by Augnition, a small R&D company based in Helsinki, Finland.

We are planning to implement multiplayer, although it won't be available for the initial public alpha.
