NovelAI

NovelAI is an AI storytelling platform with custom story models, lorebook memory, and strong privacy for fiction writers and roleplayers.

Overview

NovelAI runs on fine-tuned large language models trained specifically for storytelling, giving writers granular control over prose style, genre, and voice. Its lorebook system injects world and character details into the context at the right moments, keeping long stories internally consistent. Writers can set authorial style presets, adjust randomness and repetition penalties, and steer the narrative with editing controls at each step. The service also includes an anime-style image generator for character art, and all stories are encrypted client-side for privacy. The generation controls are unusually deep: writers can bias specific phrases, adjust token probabilities, and shape prose rhythm in ways that consumer chatbots never expose. Memory settings and author’s notes let experienced users steer long arcs deliberately. The community publishes style presets that reproduce genres from gothic horror to hard science fiction.

Pricing

NovelAI uses a subscription model with tiered monthly credits for text generations and image generation, plus a free trial with a small generation allowance. Higher tiers unlock larger context windows, faster generation, and more image credits. Subscriptions include both text and image credits, and unused Anlas credits on higher tiers carry practical value for heavy users.

Who Is It For

NovelAI is for fiction writers, worldbuilders, and interactive storytellers who want deep control over style and lore, and who value privacy for unpublished manuscripts and roleplay sessions. Interactive fiction enthusiasts who value privacy for unpublished or personal material form a loyal core audience.
