NovelAI
Subscription anime image generator and AI writing suite with private, uncensored creative tools.
About
NovelAI has been the reference anime-style AI image generator since 2022, built around its NAI Diffusion models trained specifically for anime aesthetics with Danbooru-style tag prompting. It pairs image generation with an AI writing environment (Kayra 13B, Erato 70B, Xialong 355B MoE) and a lorebook/world-building system, aimed at illustrators and storytellers who want a private, subscription-based canvas rather than a public gallery.
In August 2026 NovelAI launched Diffusion V5, trained on 268,000 B200 GPU-hours — 2.5x the size of V4.5 — alongside Vibe Transfer and Precise Reference features. Pricing runs $10/mo Tablet, $15/mo Scroll, and $25/mo Opus, with image generation metered in Anlas credits; Opus historically offered unlimited standard-size generations, though V5 draws from a rechargeable allowance instead.
Limitations: models are purpose-built for anime illustration and poor at photorealism; there is no real free plan (only a 30-image trial); the V5 usage-limit change drew subscriber complaints; and the closed, curated environment offers less model variety than community platforms like PixAI.
