We see Endless Visual Novel primarily as a game, not a writing tool. We want EVN to be 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 story will turn out. Thus, you could also think of EVN as a tool for creating Choose-Your-Own-Adventure (CYOA) visual novels.

The underlying engine is about 90% done. The video you see above is cut from alpha test gameplay, though some menu interactions have been cut for clarity.

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

The sprites are generated using a finetuned StyleGAN2 model. In the initial version, the backgrounds are AI-filtered photos, although we will implement an approach using e.g. VQGAN and CLIP to generate backgrounds from scratch. This will also allow us to make "CGs" or illustrations especially made for a specific scene.

Initially the generation process will be fully random, but we will implement various ways to steer it later on, so you can get the backgrounds and sprites you want to see.

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

We started a closed alpha during August 2021 and have since inproved EndlessVN with user feedback on Discord. We accept new users in small batches every now and then, if you're interested to join please fill the alpha signup form on the top of the site. We are launching the public alpha in April of 2022.

We will have three tiers: Free, Voyager and Creator. Players in the Free tier will be able to play 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 will be using 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 will not be encrypted, but we will not be able to link them 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 will eventually be 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.
