OselAI Inc. (hereinafter OselAI) announces the official release of 'AI Scenarist Agent', an AI scripting tool specialized in long-form story creation.
'AI Scenarist Agent' is an AI scripting and scenario writing tool for corporations and individual writers, carrying the brand promise of 'AI Writing Tool: Your Ideas into Commercial-Grade Works.' Users can simply speak their ideas, and it will assist in constructing long story structures and writing scripts, supporting the creation of commercial-grade works.
This service is an 'all-in-one AI scenario writing assistant aimed at mass-producing professional-quality first drafts of scenarios without the need for prompts.' It provides end-to-end support for conception, organization, writing, and editing, aiming for a production environment where creators can spend their time on the ideation and nuances they should originally focus on.
At the core of this service is OselAI's proprietary patent-pending 'Story Simulation' technology. Because of this, it features the ability to consistently construct long stories while taking into account character actions, relationships, and the consistency of plot developments, rather than just generating text. Furthermore, it is equipped with a feature that allows users to import existing works and conceive/write sequels or derivative scenarios in their own way.
In recent years, while the use of generative AI has spread rapidly, challenges remain in production sites for games, anime, movies, video, VTubers, and scenario production, such as 'having ideas but being unable to finish writing them as a long-form,' 'lacking writing skills or time,' and 'structural breakdowns or continuation of updates.' AI Scenarist Agent provides a new production experience addressing these issues through an AI agent that even beginners can handle and a design specialized for long-form stories.
The World's First AI Scripting Tool Specialized for Long-Form Stories *
At OselAI, this service is positioned not as a substitute for generic AI chat or general writing software, but as an AI scripting tool specialized for long-form stories. Unlike writing/editing-centric tools like Word, the AI agent supports story creation itself. Unlike generic AI like ChatGPT, Gemini, or Claude, it features optimization for conception, deployment design, importing existing works, and collaborative writing necessary for long-form story development.
AI Scenarist Agent adopts a design where, upon inputting an idea, the AI assembles a long-form work while foreseeing the automatic generation of story plots and characters, all the way to foreshadowing recovery.
* Based on our research. As of April 2026, based on public information. As an AI scripting tool provided in Japanese that provides end-to-end support for long-form story conception, consistency management, script writing, and continuations of existing works, with patent-pending 'Story Simulation' technology at its core.
Patent-Pending Story Simulation Technology
'Story Simulation', the core technology of AI Scenarist Agent, is a proprietary technology that can establish long-form works by reproducing character behaviors and taking story developments into account. By using such technology, AI Scenarist Agent supports most of the processes that traditionally relied on manual work.
Main Features of the Official Version
1. An AI Agent that Advances Story Production Just by Speaking Ideas
Users simply input fragmented ideas, settings, world views, and character profiles in their heads, and the AI agent supports script/scenario production. It provides end-to-end support from bouncing ideas in the conception stage to plot construction and writing.
2. Patent-Pending 'Story Simulation' Technology
A proprietary technology that can construct any long story while maintaining the consistency of character actions, emotions, and story developments. It enables the generation of consistent scenarios that can be read as a long-form work, not just one-off outputs.
3. Importing Existing Works and Creating 'Your Own Continuation'
By loading existing scenarios or works, you can conceive and write your own sequels or derivative stories. It supports a wide range of uses, including planning reviews of existing IPs, organizing ideas for secondary creations, and story production that inherits a world view.
4. Collaborative Writing Environment Supporting Everyone from Beginners to Corporate Production Sites
In addition to support from the AI agent, it supports collaborative writing in an editor. It can be utilized not only for individual creative activities but also for multi-person production processes such as games, anime, video, and VTuber planning.
Trial Introduction at a Scenario Production Company and Verification Results
Prior to the official release, a trial introduction was conducted at the industry's largest scenario production company, demonstrating significant productivity improvements and quality surpassing general-purpose LLMs, significantly reducing the burden of actual production for users.
