AI Workflow Builder "Stella Craft" Now Available

SUPERNOVA Inc. (Headquarters: Minato-ku, Tokyo; President and CEO: Touken Kimoto; hereinafter referred to as "our company"), a developer of generative AI services, will begin offering the AI workflow builder "Stella Craft" as an option for its generative AI service "Stella AI for Biz" starting July 1, 2026 (Wed).

Service Overview

"Stella Craft" is a no-code workflow builder that automates entire business processes with AI. It is offered as an option for "Stella AI for Biz." Triggered by schedule activation or external integration, it executes a series of tasks such as research, document generation, cloud storage, and email notifications without human intervention. Furthermore, created workflows are not limited to internal use; a URL can be issued through a form, allowing anyone outside the company to use it. This ability to be utilized beyond internal operational efficiency is a key differentiator from existing tools.

Background

Need for Automation of Routine Tasks and Limitations of Chat-based AI

While AI adoption for individual tasks is rapidly progressing in many companies, a next-phase demand for "completing entire routine task flows with AI" is becoming apparent.

Chat-based AI requires human initiation, confirmation, and instruction each time. In contrast, "Stella Craft" operates as a workflow, pre-defining steps and executing operations without human intervention. "Stella Craft" is easy to implement for routine tasks with defined procedures and excels in reproducibility, stability, and manageability.

Token Cost Issues with Agent-based AI

As companies expand their AI utilization, managing token costs has become a significant challenge. Agent-based AI makes autonomous decisions and executes tasks, making it difficult to predict how many times the LLM will be called for a single task, posing a risk of unlimited costs. This is one of the reasons for governance concerns that make companies hesitant to adopt it. "Stella Craft" pre-fixes the workflow steps, allowing for an estimate of credit consumption before execution, thus balancing cost management with task automation.

Usability Challenges for Frontline Staff

"Dify," a well-known no-code AI tool, has low usability due to the complexity of initial setup and configuration, often requiring reliance on engineers. "Stella Craft" is designed to be intuitively assembled with no-code, making it easy for beginners to use. Frontline staff who understand the business operations can create and manage it themselves. When editing, users can choose between Basic mode and Pro mode. Beginners can operate intuitively with minimal settings, while advanced users can finely adjust model parameters and output formats.

Function Details

Supports Diverse Activation with 3 Types of Triggers

Three types of triggers can be selected as the starting point for workflows: "Schedule" for automatic activation at specified times (daily, weekly, monthly, etc.), "Form" for activation upon submission of responses to a dedicated form, and "External Service Integration" for activation upon receiving data from external services via Webhook or API. When the Form trigger is selected, a user-facing form screen is automatically generated.

Define Operations Freely with Abundant Nodes

Combine Action, Context, and Output nodes like building blocks to construct workflows with no-code, tailored to the operations you want to automate.

Operation Tailored to Proficiency with "Basic Mode" and "Pro Mode"

When editing workflows, you can switch between "Basic Mode" and "Pro Mode." "Basic Mode" displays only the minimum necessary settings for each node, allowing intuitive operation even without knowledge of generative AI or workflows. "Pro Mode" allows for fine-grained control over detailed parameters such as AI model Temperature and Max Tokens, as well as output formats, catering to advanced users who aim for maximum accuracy.

Not Limited to Internal Use: Also Available Externally

By externally publishing created workflows as forms, client companies can allow anyone outside the company, including business partners and end-users, to use the workflows via a URL. This enables the automation of internal business operations and external utilization through a single tool, such as a help desk for automatically answering customer inquiries or a form that generates documents based on input.

Future Outlook

"Stella Craft" has accumulated use cases aligned with actual business workflows through joint verification with NTT DOCOMO, Inc.'s Crosstech Development Department and demonstrations in multiple local governments. The service is being launched after thoroughly confirming its practical usability in the field.

Generative AI technology is evolving daily, with new services emerging one after another. We will fully leverage the latest technologies to provide user-friendly, high-quality services to our customers, acting as a bridge connecting technology and people, and contributing to the realization of a society where no one is left behind.
