## TL;DR
AI is the infrastructure layer of remote work -- summarizing meetings, surfacing knowledge, optimizing schedules, and connecting distributed teams. From Zoom AI Companion to Slack AI to Microsoft Viva, AI tools make remote and hybrid work more productive than office-only models.

## Core Explanation
Remote work AI: (1) Meeting intelligence -- transcription (Whisper, Azure), summarization, action item extraction, and smart chapters. Zoom AI Companion and Teams Copilot provide these natively; (2) Knowledge management -- Slack AI surfaces relevant past conversations; Notion AI Q&A over team wiki; Google Workspace Duet AI for document-based queries; (3) Scheduling -- Clockwise AI auto-schedules meetings optimizing for focus time and time zones. Calendar analytics identify meeting overload; (4) Async communication -- Loom AI generates video summaries and chapters. LLM-based async updates replace status meetings.

## Detailed Analysis
Zoom AI Companion (2024): free for paid accounts, leveraging GPT-4o. Features: meeting summary (email after call), smart recording chapters, catch-me-up (late joiners ask AI what they missed), and whiteboard generation. Microsoft Teams Copilot: combines meeting recap + action items + real-time translation. Integrated across Outlook, Teams, and Office. Slack AI: search answers with citations ("summarize the Q3 launch discussion"), channel summaries (daily digest), thread summaries. Notion AI: Q&A over connected knowledge base. "What is the PTO policy?" -> AI retrieves and summarizes from team wiki. Microsoft Viva: aggregate productivity analytics. Privacy-preserving: anonymized at team level (not individual surveillance). Key tension: productivity monitoring vs. employee trust. EU regulation restricts algorithmic management (must be transparent, challengeable).
