AI Novelist, by Bit192, is a Japanese-language storywriting AI trained on a corpus of more than 2TB, letting fiction writers draft novellas and prose from prompts or their own text.
About
AI Novelist (Japanese name: AIのべりすと) is a Japanese-language storywriting AI developed by Bit192, Inc. It is designed for people who want to write fiction in Japanese with generative assistance, addressing the challenge of drafting long-form prose that matches particular genres and literary voices.
The service, currently at version 2.0, describes itself as the largest publicly available Japanese storywriting AI, trained on a corpus exceeding 2TB of text — roughly equivalent to 1.74 million paperback volumes, according to its site. Users can begin a story from one of the built-in example prompts or start from their own text. The platform hosts several distinct writing models, each with its own stylistic character, and offers official style mods that reshape the output's prose voice; users can also train custom mods from their own writing. The site notes that its research has been supported with Cloud TPUs from Google's TPU Research Cloud (TRC).

Who It's For
AI Novelist is aimed primarily at Japanese-language fiction writers, including light novella and web novel authors, hobbyists experimenting with AI-assisted storytelling, and tabletop RPG groups that want an automated narrator for replay-style transcripts. It also suits prompt-curious users who want to try AI writing through pre-built games and generators, as well as developers who may integrate its writing models through the API. Note that its output is Japanese, so it serves readers and writers comfortable with that language rather than general multilingual audiences.
