🔮 Future ImplicationsAI analysis grounded in cited sources
ATOK's unified premium model may accelerate migration to free AI-powered alternatives if the 660 yen/month price point fails to justify the feature set against emerging free competitors.
The pricing consolidation eliminates budget-tier options, potentially pushing cost-sensitive users toward free IMEs with AI capabilities.
Cross-platform ATOK MiRA rollout (Feb-June 2026) positions ATOK as a mobile-first writing assistant, not just a desktop input method.
Phased availability across Windows, macOS, iOS, and Android suggests ATOK is repositioning from IME-only to a broader writing productivity ecosystem.
