AIのべりすと (AI Novelist)

What is AI’s Belisuto?

AI Berisuto, also known as AI Novelist, is a platform developed by Bit192 for generating and assisting with the writing of Japanese novels. Once users provide the beginning of the story, character details, or the next part of the plot, the AI can continue writing the text and offer different possible directions for its development.

The platform places emphasis on Japanese literature and story creation, with a training dataset claimed to be larger than 2TB. It also offers a web editor, style MODs, character books, a chat assistant, tools for image creation, and developer APIs.

A one-sentence summary

AI’s Berrisuto is an AI tool dedicated to continuing Japanese novels and enabling creative writing; it is suitable for developing light novels, literary narratives, as well as stories featuring character dialogue and interaction.

Current main models

The models are continuously updated, and names such as SuperTrin and Yamiotome mentioned in older tutorials may not represent the preferred options at present. Before creating something, it is necessary to consider the actual models available in the editor as well as the membership privileges one has.

Main functions

Continuation of the story

Users can enter the beginning of a novel or an existing paragraph, so that the AI can continue writing from the position of the cursor. After the output is generated, the text that isn’t satisfactory can be modified directly, after which the model can proceed with writing in accordance with those changes.

Generate the text based on the plot.

The Spiko series allows for the expansion of scenarios based on specific plot points, making it suitable for converting an outline into full text section by section. Each time, about 300 to 1000 words of content to be written are entered; this approach is usually more stable than trying to send the entire story structure at once.

Combination of instructions and continuation writing

Users can insert commands within the main text to request a change in perspective, progression of the scenario, or analysis of the current situation. Unlike ordinary chat tools, the AI’s responses and the user’s text can be edited repeatedly in the same document.

Default, Solid, and Colorful modes

For some Lite models, Solid cannot be selected; Colorful may also invoke different sub-models. It is possible to start a paragraph using the default option or Solid first, and then switch to Colorful to continue expanding it.

Thinking model

Some Spiko models first carry out a thinking step before generating the text, in order to improve the understanding of complex instructions and ensure consistency in the narrative. The thinking module is usually active only in the default and Solid modes; it is not used in Colorful mode.

If speed is of greater importance, the version that operates without deliberation can be chosen; however, its performance may decline when dealing with long contexts and complex logic. The conclusions drawn in this manner may also contain errors and should not be regarded as factual evidence.

Style MOD

Official-style mods allow for an instant change in the writing style, and they also enable users to train custom styles using their own text. The available styles include light novels, emotional short stories, romantic novels, history of the Warring States period, urban legends, Western dark fantasy, and records of TRPG sessions.

• The light novel style is suitable for brisk dialogue and the pacing of online novels.
• Romantic novelists use them in descriptions of emotional relationships and modern love stories.
• The historical novel generator provides an atmosphere for a particular era, but it does not guarantee historical accuracy.
• The grotesque and urban legends are suitable for online horror and mystery short stories.
• The TRPG style allows for the creation of a GM, narration, and dialogue among multiple characters.

Character books and setting management

Character books are used to store information about characters, locations, organizations, and the world’s setting, and they provide context when relevant terms appear. In complex works, it is necessary to assign clear keywords to each entry, so as to prevent irrelevant details from taking up valuable context space.

Chat and interactive gameplay

Users can import chat prompts to converse with fictional characters or create text-based simulation games. The new version of the Spiko model is not fully compatible with some older chat scripts; it is recommended to recreate the documents using the “New Assistant” mode.

Which users are it suitable for

• Japanese web novel authors: Write sequels to light novels, as well as love and fantasy stories.
• Chinese author: Assists in conceptualizing the plot, dialogue, and character tones for the Japanese version.
• Scriptwriters and game designers: Create draft scenes, character dialogues, and side story ideas.
• TRPG players: Generate session transcripts, NPC reactions, and event descriptions.
• Japanese learners: Observe natural narratives and vocabulary, but manual proofreading is required.
• Developer: Integrate Japanese generation capabilities into games or creation tools through APIs.

Members and Prices

AI Berisuto offers free access, as well as membership tiers such as Voyager, Novelist, and Platinum. Different payment methods may result in varying prices including taxes; as of August 24, 2026, the official website does not display a unified, up-to-date price that can be easily checked.

The catalog does not consider the amounts stated in older articles as the current official prices. When preparing to subscribe, you must log in to your account; the prices in yen including taxes, the duration of the subscription, automatic renewal options, and payment methods are all determined by what is displayed on the member purchase page.

What to consider when choosing a package

• The length generated each time and the actual number of writing sessions per day.
• Does the model include advanced options such as Spiko Ultra?
• Can the context accommodate long texts, settings, and character profiles?
• Are priority queues or dedicated resources available during peak hours?
• Permissions for using style mods, scripts, and developer APIs.
• Whether the monthly subscription is renewed automatically, and the effective date after cancellation.

Basic usage tutorial

1. Register an account and access the list of works to create a new document or a new assistant.
2. Select a model that matches the topic; beginners can start by using the recommended models.
3. Enter a clear opening paragraph that includes the characters, the location, and the current conflict.
4. In the input field, enter one or two things that need to happen next.
5. Select the Default, Solid, or Colorful mode and generate the text.
6. Remove the irrelevant content and simply adjust the tone of the characters and the key facts.
7. Continue sending short commands to have the AI expand on the revised text.
8. Create character entries for recurring characters and locations.
9. Back up the work by chapter, and carry out manual editing before publishing it.

Full-length novel workflow

1. First, write a sentence outlining the story’s goal, the core conflict, and the intended outcome.
2. Split volumes, chapters, and scenes; do not send the entire narrative at once.
3. Each scenario provides only the current character, location, goal, and obstacles.
4. Use the Solid mode to handle logic, foreshadowing, and complex actions.
5. Use the default mode to complete the main narrative, and then employ Colorful to find unexpected expressions.
6. Write the established character profile and world rules in the character book.
7. At the end of each chapter, check the timeline, perspective, names, and character motivations.
8. Copy the final text to a local document, keeping track of the versions.

Methods to improve generation quality

• Provide specific sensory details, rather than just saying “describe it more vividly”.
• Advance one or two plot points at a time to prevent the model from rapidly reaching its climax.
• Clarify the perspective, tense, narrative distance, and proportion of dialogue.
• Use short examples to illustrate the desired tone; do not include entire copyrighted novels.
• When duplicates are generated, adjust the penalty for duplication appropriately, rather than simply increasing the randomness.
• When the plot gets out of control, delete the incorrect sections and regenerate them from the last correct position.
• For historical and contemporary themes, characters, dates, places, and institutions are verified separately.

Main advantages

• It is designed for Japanese novels and narrative texts, with a clear stylistic orientation.
• It also retains both continuation-based editing and imperative creation.
• A variety of old and new models are available, taking into account logic, speed, and surprise.
• The style MODs cover light novels, literature, horror, history, and TRPGs.
• It supports directly modifying the AI-generated text and then continuing with generation.
• Character books help to maintain long-form characters and worlds.
• It provides OpenAI-compatible interfaces as well as traditional text completion interfaces.

Usage restrictions and precautions

• The interface and help materials are primarily in Japanese, which poses a learning barrier for Chinese users.
• Free users may encounter queue, usage limit, or cooling-off restrictions.
• The model may forget lengthy early settings, and manual maintenance of the summary is still required.
• Historical, scientific, and factual information may contain errors.
• Style imitation may result in expressions that are too similar to those of existing authors.
• The new and old models may not be fully compatible with scripts and chat prompts.
• Advanced models, long contexts, and APIs may be subject to membership permission restrictions.
• The fact that the generated content can be used for commercial purposes does not mean that copyright and reputation risks are automatically eliminated.

Commercial and copyright rules

The terms of service permit users to use the generated articles and images for personal or commercial purposes, on their own responsibility. The platform does not guarantee that such content does not violate third-party rights, nor does it carry out any checks regarding facts or copyrights on behalf of the users.

Users should not enter unpublished materials, personal information, or entire protected works that they are not authorized to handle. Before publishing, it is also necessary to check for characters, trademarks, real persons, quoted passages, and expressions similar to existing works.

Secure release checklist

• Rewrite each section manually and standardize the characters’ tone.
• Check for any real personal information or defamatory descriptions.
• Verify all historical, medical, legal, and financial facts.
• Verify that the reference text and training MODs have legitimate usage rights.
• Save records of the creation process, manual modifications, and authorization details.
• Comply with the labeling requirements for AI-generated content set by the publishing platform.

Privacy and data processing

The platform may collect email addresses, payment information, content submitted by users, IP addresses, access logs, Cookies, and identifiers of external accounts. This data is used for account management, authentication, settlement, improving services, analyzing traffic, displaying advertisements, and dealing with violations.

Payment and advertising processes may involve Stripe, PayPal, PayPay, as well as advertising partners. Do not include in the novel’s details any identification documents, real addresses, confidential contracts, account passwords, or other sensitive information belonging to others.

Developer API

AI.Belisuto offers experimental developer APIs that can be integrated into clients, games, and creative tools. The documentation focuses on a quick start guide; the interfaces are still under development, and compatibility issues need to be taken into account for production projects.

Comparison of interface capabilities

Models such as Spiko Ultra can use OpenAI-compatible endpoints and support streaming output. The official examples specify that the context limit for Spiko Ultra is 200,000 tokens, with a maximum output of 32,768 tokens; however, the actual permissions and available models depend on the account in question.

API integration steps

1. Confirm API eligibility in the account and create a key.
2. Choose either the chat interface or the text completion interface.
3. Truncate the main text and character books according to the model’s context constraints.
4. First, use short texts to verify the Japanese encoding, streaming return, and termination conditions.
5. Set timeout, retry settings, concurrency limits, and cost controls.
6. Do not write the key in the frontend, public repositories, or project files.
7. Record the model name and parameters to facilitate the reproduction of important outputs.
8. Before going live, prepare fallback solutions for interface changes and service disruptions.

Open-source status

The AI Blessot product itself is not made available as an open-source project; its web services and model weights cannot be deployed privately using it. The editor plugins, clients, and packaging libraries available online are mostly third-party projects, and they are not maintained by the official team.

The authorities have made available information on how to use the Tokenizer as well as the developer APIs, but the availability of these interfaces does not mean that the source code of the platform is also available. When using unofficial extensions, it is necessary to check the license terms, key handling procedures, and update status.
