About NovelAI

NovelAI is a premier subscription-based service providing AI-assisted authorship and generative art through proprietary Large Language Models (LLMs) and custom Diffusion models. Positioned as a leading alternative to mainstream LLMs, NovelAI differentiates itself through a strict 'No-Logs' privacy policy where stories are encrypted locally using AES-256, ensuring that even the platform providers cannot access user content. Its flagship model, Kayra (13B parameters), is custom-trained on high-quality literature, offering a nuanced prose style superior to general-purpose chat assistants. Technically, it leverages a unique 'Lorebook' system—a sophisticated JSON-based retrieval-augmented generation (RAG) framework that allows users to define persistent world-building elements, characters, and logic that the AI references contextually. In the 2026 market, NovelAI stands as the gold standard for creative freedom, intentionally avoiding the restrictive RLHF (Reinforcement Learning from Human Feedback) filters that limit competitors, making it the primary choice for professional novelists, tabletop RPG enthusiasts, and concept artists seeking uncensored, high-fidelity creative collaboration.
