Overview

NovelAI is a generative storytelling platform that continues text from an existing opening and the author’s instructions. Its models are fine-tuned for narrative writing and can be guided through memory, author notes and detailed generation settings.

Lorebook stores characters, locations, objects and world rules so relevant information can be inserted when needed. Text Adventure mode turns user actions into narrative responses, while phrase bias settings influence vocabulary and recurring motifs.

The service also includes anime image generation and text to speech, but story generation remains a central use case. A subscription is required after the limited trial, and the writing experience is primarily suited to English.
