## Summary

Microsoft Copilot has evolved since its launch in November 2023, shifting from a basic chat feature to a more capable tool integrated with Office apps. The addition of Anthropic’s Claude model in 2025 marked a turning point, enhancing capabilities in PowerPoint and Excel. Users now report practical improvements, such as generating slides matching corporate templates and automating data tasks in spreadsheets.

The service now offers a flat-rate monthly license—¥3,000 for up to 300 seats or ¥4,500 for more—competing with pay-as-you-go alternatives. While some high-performance models may have usage limits, the flat fee supports iterative refinement of prompts. Early adopters benefit most, as mastery requires trial-and-error instruction tuning. The author, a Microsoft 365 user, concludes Copilot’s quality now justifies the cost for businesses already using the suite.

## Key points

- Claude model integration in 2025 improved PowerPoint slide generation and Excel data tasks, per user reports
- Monthly flat-rate pricing starts at ¥3,000 for up to 300 seats or ¥4,500 for more, per article
- Work IQ feature combines Office data (emails, Teams transcripts) with Copilot for project summaries and drafts

## Why it matters

For Microsoft 365 users, Copilot’s Claude-powered Office integrations now deliver tangible productivity gains, reducing manual work in presentations and spreadsheets. The flat-rate model also lowers risk for businesses testing generative AI tools.
