OneBot Service Specification

• Service Name: OneBot
• Content: A corporate-oriented AI chatbot service using generative AI and knowledge-search technology, generating natural-language answers based on registered knowledge.
• Form of Provision: Cloud service (SaaS).
• Eligible Users: Corporations, organizations, educational institutions and other organizations recognized by the Company.

The Service provides the following features within the scope of the contract plan, order form, quotation or individual contract:

• AI Chat — generative-AI responses to user questions.
• Knowledge Search — searching registered documents/knowledge base to generate answers.
• FAQ Response — answers based on pre-registered FAQs.
• Administration — user, knowledge, permission, AI-setting and usage management (available items vary by plan/permission).
• Web Chat / LINE Integration (eligible plans) — chat widget on websites and LINE integration via the LINE Messaging API.
• Document summarization / drafting support are optional features provided only where included in the plan or individual contract.

The Service currently uses Google Gemini as its AI platform. The Company may change the model where necessary for quality, security, cost or provider specification changes; material changes are notified within a reasonable scope. The Service supports BYOK (Bring Your Own Key): a Customer may configure its own Google Gemini / Vertex AI API key, in which case API usage fees are billed under the Customer’s own contract with that provider.

The Service may store user information, chat history, knowledge data, uploaded files and various logs to the extent necessary for provision, maintenance, incident response, security and usage monitoring. Unless otherwise agreed, stored data is kept in a cloud environment with appropriate security measures, with primary storage located within Japan (primarily the Vultr Tokyo region). Transmission of data to the Google Gemini API is carried out as an entrustment under Article 27(5) of the APPI. See Privacy Policy Article 8 for details.

The Company performs backups to ensure service continuity. Backup configuration may be kept private for operational reasons. Backups aim at continuity and disaster recovery and do not guarantee complete restoration of all data.

• HTTPS communication.
• Encryption of stored data, storage and backups (including encryption by cloud environment or database functions).
• Access control, authentication management and permission management.
• Log audit, vulnerability management and security updates.

The Company uses its best efforts to provide the Service stably and continuously. Where a specific availability target value is required, it shall be set separately in an individual contract or order form. Unless otherwise provided in an individual contract, the Company does not promise refunds, reductions, service credits or other compensation. Excluded from any availability calculation: planned maintenance; failures originating from the customer’s environment; internet failures; failures or specification changes of external AI services, cloud or LINE; and failures due to force majeure.
