AIのべりすと Guide: How to Write Novels with AI and Use the TrinArt Image Feature

AIのべりすと is a novel-generating AI tool developed by Japanese game creator Sta. Often described as one of the most powerful Japanese-language AI writing tools, it creates full-length stories from just a short opening passage. Because it was built by a Japanese developer, it handles Japanese text with particular strength. This guide explains its features, how to use it, and its new image generation capability, and notes that commercial use is allowed, so writers can even publish their work.

AIのべりすと makes creative writing accessible to everyone. It offers 34 genres, including space opera, medical drama, mystery, dark fantasy, history, period drama, yuri/BL, school life, magical girl, time travel, and zombies. Selecting a genre automatically shapes the storyline and tone of the output. For example, choosing 推理 (mystery) brings detective-style plots, while 時代劇 (period drama) produces samurai-era dialogue. Writers can then expand and personalize the AI-generated text to create original works.

The service is free to use, but free accounts have output limits; once the limit is reached, output is unavailable for 180 minutes. Free users are limited to about 2,500 characters of recognized text and roughly 100 characters of output per generation. Paid tiers—Voyager (1,166 yen/month), Bungo (1,980 yen/month), and Platinum (3,465 yen/month)—offer higher character limits, longer output per generation (up to about 375 characters on Platinum), dedicated servers, and more Lumina credits for image generation. Platinum offers unlimited output on dedicated servers. Serious writers are advised to consider a paid plan.

Although the tool can be tried without signing in, text beyond a certain length triggers an error, so creating an account is recommended. Click 「新規アカウントをつくる」 at the top right of the home screen, then enter an email address and password to complete registration.

In novel mode, select from three styles: デフォルト (the AI writes freely, imitating your input), セリフ (prioritizes dialogue, often starting output from within quotation marks), and ナラティブ (prioritizes descriptive narration with concrete expressions and fewer metaphors). Beginners are encouraged to start with the default mode. Chat mode lets users converse freely with the AI after entering a name and clicking 「このプロンプトをインポート」. If the AI only replies 「ごきげんよう」, adjust the writing style via the gear icon or raise the 「繰り返しペナルティ」 value in advanced options.

Free users use the 「とりんさま7.3B」 model, which generalizes many concepts and tends to produce straightforward responses. Paid members can choose other models: でりだ7B, which excels at poetic expression; スーパーとりんさま, which reads context and outputs up to four times faster than やみおとめ20B; やみおとめ20B, a 20-billion-parameter model strong with rare kanji and proper nouns; and the experimental English models Neuman 13B (basic novels) and Neuman 20B (code and chatbot-style roles). Models can be changed anytime under the account's user settings.

Within the pin-icon story settings, two tools help maintain consistency. The Memory feature stores important details—such as a character's age or background—so the AI doesn't forget them as the text grows. Free accounts recognize about 2,500 characters, and paid accounts up to 5,000. Footnotes have higher priority than memory and are ideal for specifying genre (e.g., [ジャンル：〇〇]) or planned plot directions, helping keep the story on track.

AIのべりすと also includes TrinArt, a text-to-image generator accessible via the 「お絵かき」 option at the top right. Users enter a prompt and click 「絵を描く」 to generate an image. If you're unsure what to write, the 「ヘルプ」→「テクニック」 section provides sample prompts. The gear icon offers settings for model and drawing mode. Each generation consumes about 0.26 Lumina, and the number of Lumina credits depends on the membership plan.

With its option settings, story tools, and flexible input methods, AIのべりすと can produce text approaching professional novel quality. Its outputs can be refined into many different kinds of writing. The core service is free, while paid plans offer unlimited output for longer works. For anyone interested in creating a novel, AIのべりすと is well worth exploring.
