A creative platform developed and operated by Anlatan that combines anime-style illustration generation with story writing. Launched in 2021 as an AI novel-writing service, it later added a proprietary image generation model and grew into a service where you can create both art and stories. The latest image model, NovelAI Diffusion V4.5, supports multi-character scenes and natural-language prompts, while the text side offers proprietary models with a large context window for long-form fiction. Everything runs in a web browser under a subscription model.
Key Features
- Anime-specialized image models: The proprietary NovelAI Diffusion series (currently V4.5) renders diverse anime styles. It supports positioning and interactions between multiple characters, natural-language prompting, and rendering English text inside images
- Vibe Transfer: Extracts only the “vibe” of a favorite image and carries it into new generations — a way to inherit an art style or tone that is hard to put into words
- Character consistency: Character reference tools keep the same character looking consistent across different poses and scenes
- Long-form writing models: The proprietary Kayra model, the Llama 3-based Erato, and the Opus-exclusive large model Xialong. A context window of up to 28,672 tokens preserves the flow of long stories
- Canvas editing tools: Retouch generated images right in the browser. Beyond inpainting, it includes clone stamp and blur tools plus 3D pose manipulation
- Privacy-minded design: Stories are stored encrypted, and NovelAI states that what you write is not used to train its models
Pricing

|---|---|---|
| Paper (free trial) | $0 | Trial tier. Up to 30 image generations (max 1024x1024), limited text generation |
| Tablet | $10 | Unlimited text generation, 1,000 Anlas (image generation credits) per month |

| Opus | $25 | Effectively unlimited standard-size image generation (with conditions), 10,000 Anlas per month, top-tier text models such as Xialong, maximum context |
Image generation consumes credits called “Anlas”; the Opus plan generates without spending Anlas as long as conditions such as standard size and one image at a time are met. Pricing is as of August 2026. Check the official site for the latest pricing.
Pros & Cons
✅ Pros
- Well regarded for anime and manga-style image quality, reliably producing styles that general-purpose image generators struggle with
- One subscription covers both illustration generation and novel writing
- Practical creator-focused features such as Vibe Transfer and character references
- Runs entirely in the browser — no local GPU setup required
- Privacy-conscious handling of creative work, including encrypted story storage
⚠️ Cons
- No permanent free plan; continued use requires a subscription
- Heavy or high-resolution image generation may require purchasing extra Anlas
- Photorealistic images and business illustrations are not its strong suit
- The UI supports Japanese, but documentation and community resources are mostly in English
- The writing models are strongest in English; quality can be inconsistent for long-form fiction in Japanese

Who Is It For
- Anyone who wants consistent, high-quality anime and manga-style illustrations without building a local environment
- Doujin artists and web comic creators who need to draw the same character across multiple scenes
- Creators who want to consolidate their workflow — from story drafts to illustrations — into a single service
- Privacy-minded writers who do not want their AI-assisted stories used for model training
Summary
NovelAI unifies two creative aids — anime-style image generation and AI novel writing — into a single, clearly focused subscription. Its scope is narrower than general-purpose image generators, but for anime and manga-oriented creation, the expressive power of the V4.5 model and its character consistency features are compelling. Start with the free Paper tier to see whether the art style fits, and consider the Opus plan for serious use, where standard image generation becomes effectively unlimited.
