■ About This Update
Since its release in January 2026, "GEAR.indigo Biz" has been increasingly adopted, primarily by contract development businesses and in-house development teams.
This update introduces support for BYOK (Bring Your Own Key).
【BYOK (Bring Your Own Key) Support】
Customers can now connect and use their existing API keys from services such as OpenAI, Anthropic Claude, and Google Gemini directly with "GEAR.indigo Biz."
As the configuration utilizes your own API keys, meeting notes and requirement information are processed on the AI service you have contracted with, rather than through the Company's managed AI usage environment.
This not only facilitates compliance with internal security policies but also allows you to use the tool for free when using BYOK.
Furthermore, the BYOK plan can be used by both individuals and organizations.
For organizational use, team collaboration is possible within the following scope:
Item
Limit
Individual/User
Up to 10 people

Up to 3 organizations
Number of Projects
Up to 6 projects
Codebases
Up to 6 codebases

■ About GEAR.indigo Biz
"GEAR.indigo Biz" is an AI-driven solution that consistently supports the process from requirement definition to design by inputting meeting notes, hearing content, existing code, and more.
Its purpose is not merely to provide an AI tool, but to support the creation of organizations that can effectively utilize AI.
The AI understands the dependencies and prerequisites for each stage, generating and organizing deliverables, thereby preventing omissions and ensuring uniform quality.
The main features currently offered are as follows:
Generation of requirement definition and design deliverables from meeting notes, files like Excel/PDF, and Notion integration
Consistency checks and identification of missing items for each document through AI review
Reverse engineering of existing code through GitHub integration and Zip file import
Design based on existing systems (additional generation from reverse engineering)
Planning Canvas: A function to structurally organize ideas for new businesses and system planning, and to conduct hypothesis testing, market research, and ROI analysis.
AI Project Search: A function where AI automatically investigates and analyzes documents and codebases registered in projects.
