Microsoft 365 Copilot
AI assistant deeply integrated into Microsoft 365 apps — Word, Excel, PowerPoint, Outlook, and Teams — for enterprise productivity.
Gemini for Google Workspace
Google's AI assistant integrated across Gmail, Docs, Sheets, Slides, and Meet for intelligent productivity enhancement.
Amazon Q Business
AWS enterprise AI assistant that connects to corporate data sources for secure, contextual business intelligence and task automation.
/// THE_VERDICT
Microsoft 365 Copilot leads the enterprise workspace race with deep integration across Word, Excel, PowerPoint, Teams, and Outlook — its ability to draft documents, analyze spreadsheets, and summarize meetings within tools that billions already use gives it an unmatched distribution advantage. Gemini for Google Workspace counters with native integration into Gmail, Docs, and Sheets, offering a strong value proposition for organizations already on Google's platform, particularly with its generous included tiers. Amazon Q Business carves out a niche for enterprises with complex internal knowledge bases, excelling at connecting to 40+ enterprise data sources for retrieval-augmented answers that respect existing access permissions.
SCORE BREAKDOWN
DEEP DIVE
Microsoft 365 Copilot
AI assistant deeply integrated into Microsoft 365 apps — Word, Excel, PowerPoint, Outlook, and Teams — for enterprise productivity.
/// JUDGE_SUMMARIES
"Microsoft 365 Copilot benefits from Copilot Chat rolling out across Word, Excel, PowerPoint, Outlook, and OneNote — unifying the AI experience. The July 2026 Microsoft 365 price increases (Business Basic +17%, Standard +12%) further squeeze cost efficiency. Security Copilot coming to E5 customers is notable for the enterprise security market. It remains an excellent in-context assistant but functions more as a productivity enhancer than an autonomous agent."
"Microsoft 365 Copilot is at its best when you want AI help directly inside Word, Excel, PowerPoint, Outlook, and Teams without copying content into a separate chat. It can save meaningful time on drafting, summarizing, and meeting follow-ups, but it’s an expensive per-seat add-on and still needs verification on anything important."
"Microsoft Copilot (M365) is the massive force integrating AI into the 'operating system of work'. Its strength is context—it knows your emails, docs, and chats. While not a builder's tool like n8n, it is the most ubiquitous agent that will handle 80% of daily white-collar drudgery."
/// STRENGTHS_WEAKNESSES
Enterprise teams deeply invested in Microsoft 365 who want AI-powered assistance for document creation, email management, data analysis, and meeting productivity.
Gemini for Google Workspace
Google's AI assistant integrated across Gmail, Docs, Sheets, Slides, and Meet for intelligent productivity enhancement.
/// JUDGE_SUMMARIES
"The January 2025 inclusion of Gemini in all Workspace subscriptions (with 15-20% price increases) changes the value proposition — it is now bundled rather than an add-on. G2 rates ease of use at 94% and setup at 97%. However, enterprise adoption shows a stark divide: power users see significant productivity gains while mainstream users default back to standalone chatbots. Sheets capabilities remain the weakest link."
"Gemini for Google Workspace is most valuable when you live inside Gmail, Docs, Sheets, Slides, and Meet and want AI help without leaving those apps. The integrations can save real time on drafting and summarization, but experiences vary: some users report intrusive UI and uneven reliability, especially in Sheets."
"Google's answer to Copilot, embedded in Docs, Gmail, and Drive. Its 1M+ context window (via Gemini Pro 1.5) gives it a unique advantage in analyzing massive document repositories. It feels faster and more fluid in the browser than Microsoft's add-ins."
/// STRENGTHS_WEAKNESSES
Organizations using Google Workspace who want integrated AI assistance for email management, document creation, and meeting productivity within their existing Google ecosystem.
Amazon Q Business
AWS enterprise AI assistant that connects to corporate data sources for secure, contextual business intelligence and task automation.
/// JUDGE_SUMMARIES
"Amazon Q Business remains a solid enterprise RAG engine with the strongest ACL enforcement at scale in the market. The addition of QuickSight dashboard generation and the $3/user Lite tier improve accessibility. However, it functions more as a secure knowledge retrieval system than a general-purpose agent, and setup complexity remains a significant barrier even for experienced AWS teams."
"Amazon Q Business is a security-first enterprise assistant that answers questions over internal content with permission-aware retrieval and deep AWS identity integration. It’s strongest when you need tight governance and easy access through channels like the web experience and Slack/Teams, but setup and ongoing connector/index management can be heavy."
"Amazon Q Business is the 'secure' enterprise chat. It connects to 40+ enterprise data sources and emphasizes permission-aware retrieval. It's less of a personal assistant and more of a corporate oracle. For developers, the Q integration in IDEs is distinct but part of the same brand family."
/// STRENGTHS_WEAKNESSES
AWS-native enterprises in regulated industries that need a secure AI assistant connected to corporate data with strict access controls and compliance requirements.

/// SYS_INFO Methodology & Disclosure
How we rate: Each AI model receives the same structured prompt asking it to evaluate each agent across 8 criteria on a 1-10 scale. Models rate independently — no model sees another's scores. Consensus score = average of all three judges. Agreement level = score spread.
Agent criteria: AI agents are evaluated on Task Autonomy, Accuracy & Reliability, Speed, Tool Integration, Safety & Guardrails, Cost Efficiency, Ease of Use, and Multi-step Reasoning — different from coding tool criteria.
