NovelAI

NovelAI combines an anime image generator with a text generator for long form fiction. The image side runs the vendor's own diffusion model, now in its fifth version, which the site describes as producing sharper detail, more characters in a single image and complete comic pages. The story side is a writing environment where the model continues and extends a draft under the writer's direction rather than producing finished prose on its own. It is aimed at illustrators, fan artists and fiction writers who want control over output instead of a single prompt and whatever comes back. Image generation accepts both natural language prompts and tags, supports action tags, and lets characters be defined separately so each one stays consistent across a scene. The story tools carry world and character information forward so details established earlier are retained. Everything runs in the browser with no installation, including on a phone. The vendor states that accounts can be anonymous, that prompts are encrypted, and that generated images are not kept on its servers unless the user chooses to save them. The site publishes that subscriptions start at $10 a month, covering both the image and text generators and aimed at occasional creators. Higher tiers exist but their names and amounts are shown only inside the application, so they could not be confirmed from the public pages. Users who prefer not to subscribe can instead buy Anlas, the credit that fuels image generation, on demand. A trial period is offered to new users.
