RAG Tool Comparison
Build an internal RAG yourself, use a SaaS, or get by with general-purpose AI? We compare features, pricing, and security by type to help you choose what fits your company.
Do any of these sound familiar?
Per-user pricing makes company-wide rollout impossible
At over ¥2,000 per user per month, a company-wide deployment can cost hundreds of thousands of yen. Many end up limiting usage to just a few teams.
Deployment requires server setup or engineers
Open-source RAG tools are powerful, but require dedicated engineers for setup, operation, and updates. Without technical staff, you can't even get started.
Concerns about Japanese accuracy with overseas tools
Services designed for English-speaking markets often struggle with Japanese context understanding and natural UI.
Data security is unclear
Where is data stored? Is it used for AI training? Many services make it hard to verify these critical points.
No way to control information by department
When executive documents and onboarding materials are in the same place without access controls, managing confidential information becomes difficult.
Poor integration with existing tools
Services that require specific platform subscriptions are hard to fit into existing workflows and add extra costs.
