NovelAI: Anime-Style Story Writing and Image Generation 214

Novelai is an AI image and text creation platform launched by Anlatan in the US, focused on anime-style story writing and anime image generation. Beta testing began in 2021, with the image generation feature added in 2022. It supports text-to-image, image-to-image, model training, and ControlNet pose control. The model is a modified version of Stable Diffusion, specifically trained on a large volume of anime images, making it well-suited for light novel authors, fan art creators, and ACG content producers.

What NovelAI Can Do

• Writing: Novels, poetry, scripts—anything goes. Give it a starting line or keywords, and the AI continues from there. It can also rewrite or expand on paragraphs you've already written.

• Image Generation

• Text-to-Image: Type a description to produce anime-style images, with adjustable parameters like CFG and sampling steps

• Image-to-Image: Upload a photo or sketch and convert it to anime style while preserving the original pose

• Inpainting: Paint over areas that didn't turn out well and have the AI redraw only that section (e.g., fixing malformed hands)

• Vibe Transfer: "Transfer" the style of one image onto another

• Model-Related Features

• Upload your own image set to train a custom style

• Blend two models at adjustable ratios to create a new art style

• Supports LoRA for locking in a specific character's appearance

• ControlNet: Works with tools like openpose to generate images based on the reference's skeletal pose and depth, solving the problem of complex multi-character poses breaking down.

Who NovelAI Is For

• Light novel and web fiction writers who need the AI to continue when they're stuck

• Fan art creators who want character illustrations from text descriptions, saving on commissions

• Visual novel and indie game developers producing character avatars and CGs in bulk

• ACG-focused content creators who need quick accompanying images

• Manga artists converting sketches into line art or colored drafts

NovelAI Pros and Cons

The Good

• Anime style is very authentic—character faces and details are top-tier among similar tools

• Write and illustrate in one place, no need to switch between software

• Data is fully private; copyright on generated content belongs to you

• High creative freedom, NSFW content is allowed (within compliance limits)

• Accurate understanding of anime-related terminology

The Not-So-Good

• Closed-source—deep model customization isn't as flexible as running Stable Diffusion locally

• Subscription isn't cheap; heavy users can rack up significant annual costs

• Generation speed is on the slower side for cloud services; expect queues during peak times

• Backgrounds aren't as strong as characters—complex scenes tend to get muddy

• Requires an internet connection; no offline version

• Chinese language support is limited—image generation prompts need to be in English

How to Use NovelAI

• Registration and Payment: Go to novelai.net to register and pick a plan. The basic plan doesn't include image generation; the standard plan starts around $10/month. After payment, you receive tokens (Anlas), which are deducted per generated image.

• Text-to-Image

• Enter Image Generation and select a model (e.g., NAI Diffusion V4.5)

• In the Prompt box, write your description—recommended to include: quality tags (masterpiece, best quality) + subject + style

• In the Negative Prompt box, write what you don't want (lowres, bad anatomy, extra fingers)

• Set CFG Scale to 7–12, sampling steps to 20–30, and hit generate

• Pick from the 4 generated images; use inpainting to fix what isn't satisfactory

• Image-to-Image

• Upload a reference image—real photos or line art both work

• Adjust the Denoising strength (0.3–0.7); higher values mean more changes

• Add supplementary prompts and generate an anime-style image while preserving the original composition

• Story Writing

• Go to the Story page and create a new document

• Enter the opening and click Continue to let the AI write on

• Use the Memory feature to lock in character settings and prevent character drift in long-form writing

• Insert style instructions in Author's Note to influence the AI's output tone

How NovelAI Compares to Other Tools

Why Choose NovelAI

If your main focus is Japanese-style anime content and you need AI to help with both writing and illustration at the same time, NovelAI is one of the few tools that brings both together. Its character art quality has a solid reputation in the anime community, and features like Vibe Transfer and LoRA give you finer control over style. For creators who don't want to deal with local setup and are willing to pay for convenience, subscribing gets you started right away with a much lower learning curve than Stable Diffusion.

FAQ

Q: Is there a free version?

It seems there's no HTML snippet provided to translate. Please paste the HTML content you'd like me to translate into English (en-us), and I'll be happy to process it for you.

Q: Can the generated images be used commercially?

Yes. NovelAI explicitly states that users have full copyright over the generated content.

Q: Why are hands always drawn poorly?

This is a common issue with diffusion models. It is recommended to add "bad hands" and "extra fingers" to the Negative Prompt, or use inpainting to fix them manually.

Q: Is high-level English required?

Image generation requires English prompts, but you don't need to be highly proficient — just refer to tag libraries shared by the community. The writing feature can accept Chinese input directly.

Q: What's the difference from Stable Diffusion?

NovelAI is essentially a polished version of SD, specifically optimized for anime style. It's easier to get started with, but offers less room for customization compared to local SD.

Q: What happens when my tokens run out?

The standard plan refreshes the quota every month, and you can also purchase add-on packs separately. Writing is deducted by word count, and image generation by image count.
