NovelAI: uncensored story writing with an anime image generator on the side

NovelAI is an AI-assisted fiction writing service paired with an anime image generator: you type a few lines and the model carries the story forward in your voice. American studio Anlatan launched it in 2021, shortly after AI Dungeon tightened its content rules, and inherited many of its writers. Plans run from $10 to $25 a month once the free Paper trial runs dry. Fanfiction authors, roleplayers and hobby novelists make up most of the crowd.

Inside the NovelAI editor, the story picks up where you stopped

NovelAI works by text continuation: you write a paragraph, the AI drafts what comes next, and every generated word stays editable. The current engine, GLM-4.6, is available on all tiers, with memory reaching roughly 144,000 characters on Opus. Enough to hold a full novel without constant reminders.

The rest of the writing kit lives on the same screen, and that is where long sagas are won or lost:

• Lorebook: character and location cards injected by keyword
• Style modules, from fantasy to gothic fiction
• Text adventure mode, where the story plays out as actions
• Text-to-speech to hear your chapters read aloud

NAI Diffusion, the anime half of NovelAI

Image generation arrived in October 2022 with NAI Diffusion, a diffusion model trained by Anlatan and specialized in anime aesthetics, now at version V4.5. Images are paid for in Anlas, the in-house currency refilled monthly with your tier.

While most AI image generators chase photorealism, this one leans into the manga look and illustrates your scenes without leaving the editor. You describe your heroine, she has a face before the next chapter (and you will never again rewrite her character sheet from memory, which was the real danger all along).

Tiers, Anlas and the language question

Three subscriptions exist, with no commitment and no annual discount, plus the Paper trial to get a feel for it.

Prices shift as Anlatan updates its lineup, so check the official subscription page before paying. On language, the models do their best work in English and Japanese; French, German and others come through decently, with a slight loss of polish.
