AI office suites in 2026 are divided by ecosystem. Microsoft Copilot owns the Word/Excel/PowerPoint workflow. Google Workspace AI owns Gmail/Docs/Meet. Notion AI owns the indie knowledge worker space. 飞书AI and 钉钉AI own Chinese enterprise collaboration. WPS AI owns the Chinese Office-compatible market.
The right choice is almost entirely determined by which ecosystem your organization already uses.
