Meeting Intelligence
The most compared feature — how each AI handles meetings.

| Summary in multiple languages | Yes — supports 30+ languages | Yes — supports 16+ languages |
| Retroactive summary (past meetings) | Only if recording/transcript exists | Only if recording/transcript exists |
Verdict: Comparable quality. Both extract action items, topics, and decisions. AI Companion supports more languages. Copilot integrates summaries more deeply into Teams channels and Outlook.
Real-Time Meeting Assistance
| Capability | Zoom AI Companion | Microsoft Copilot |
|---|---|---|
| ”Catch me up” (join late) | Yes — summarizes what you missed | Yes — summarizes what you missed |
| Real-time suggested responses | No | No |
| Live sentiment analysis | No | No |
| In-meeting Q&A with AI | Yes — ask “what did [person] say about [topic]?” | Yes — ask “what decisions were made?” |
| Real-time transcription | Yes (included) | Yes (included) |
| Speaker attribution | Yes | Yes |
| Translated captions | Yes — 35+ languages | Yes — 70+ languages |
Verdict: Nearly identical real-time capabilities. Copilot has an edge in translated caption language count. Both support “catch me up” and in-meeting AI queries.
Meeting Recordings
| Capability | Zoom AI Companion | Microsoft Copilot |
|---|---|---|
| Smart chapters in recordings | Yes — auto-generated with timestamps | Yes — auto-generated chapters |
| Highlight extraction | Yes — key moments flagged | Yes — key moments flagged |
| Recording search | Yes — search within transcript | Yes — search within transcript |
| Recording stored in | Zoom cloud | OneDrive / SharePoint |
| Recording analysis / coaching | Via Revenue Accelerator (separate product) | Via Copilot for Sales (separate product) |
Chat & Messaging AI
Compose & Reply Assistance
| Capability | Zoom AI Companion | Microsoft Copilot |
|---|---|---|
| Smart compose (draft messages) | Yes — in Zoom Team Chat | Yes — in Teams Chat |
| Rewrite / adjust tone | Yes — formal, casual, concise, etc. | Yes — formal, casual, concise, etc. |
| Thread summarization | Yes — summarize long chat threads | Yes — summarize long chat threads |
| Channel summarization (“catch me up”) | Yes — summarize unread messages in a channel | Yes — summarize unread channel activity |
| Suggested replies | No | No |
Verdict: Nearly identical chat AI features. Both can summarize threads and channels, and both help compose messages. The difference is which chat platform you use.
Email AI
| Capability | Zoom AI Companion | Microsoft Copilot |
|---|---|---|
| Email compose assist | Zoom Mail only (limited adoption) | Outlook — full draft, reply, summarize |
| Email summarization | Limited | Yes — summarize long email threads |
| Email tone adjustment | Limited | Yes — formal, casual, direct, etc. |
| Priority inbox / highlights | No | Yes — highlights important emails |
| Meeting prep from emails | No | Yes — summarizes email threads related to upcoming meetings |
Verdict: Copilot is significantly stronger for email. Zoom Mail has limited adoption and limited AI features. If your organization uses Outlook, Copilot’s email AI is a meaningful advantage.
Document & Productivity AI
This is where the two products diverge most. AI Companion is meeting/chat-focused. Copilot spans the entire Office suite.
| Capability | Zoom AI Companion | Microsoft Copilot |
|---|---|---|
| Document drafting | Zoom Docs (new, limited features) | Word — full document generation, editing, summarization |
| Spreadsheet analysis | No | Excel — formula generation, data analysis, pivot tables |
| Presentation creation | No | PowerPoint — generate slides from prompts, summarize presentations |
| Note-taking | Zoom Docs / meeting notes | OneNote — summarize, organize, extract action items |
| Whiteboard AI | No (Zoom Whiteboard has no AI features) | No (Microsoft Whiteboard has no AI features) |
Verdict: If you need AI across documents, spreadsheets, and presentations, Copilot is the only option. AI Companion is not a productivity suite AI — it’s a communications AI.
Phone & Voice AI
| Capability | Zoom AI Companion | Microsoft Copilot |
|---|---|---|
| Phone call summarization | Yes — Zoom Phone call summaries | Yes — Teams Phone call summaries (requires Copilot for Teams Phone) |
| Voicemail summarization | Yes — AI-powered voicemail transcription | Yes — voicemail transcription in Teams |
| Call coaching | Via Revenue Accelerator (separate license) | Via Copilot for Sales / Dynamics 365 |
| SMS/messaging AI | Smart compose in Zoom Phone SMS | No Teams Phone SMS AI |
Verdict: Both summarize phone calls. Zoom AI Companion’s phone features are included free. Teams Phone AI features require Copilot licensing.
Privacy & Data Handling
| Aspect | Zoom AI Companion | Microsoft Copilot |
|---|---|---|
| Data used for model training | No — Zoom states AI Companion data is not used to train models | No — Microsoft states enterprise Copilot data is not used to train models |
| Data residency | Zoom’s global data centers (configurable per account) | Microsoft’s regional data centers (follows M365 data residency settings) |
| Admin controls to disable | Yes — disable per account, group, or user | Yes — disable per user, group, or org |
| User opt-out | Users can turn off AI Companion for their meetings | Users can opt out of Copilot features |
| Meeting consent notifications | ”AI Companion is active” notification shown to all participants | ”Transcription has started” notification shown to all participants |
| Third-party participant data | AI processes all participants’ audio/content, including external guests | AI processes all participants’ audio/content, including external guests |
| SOC 2 / compliance | SOC 2 Type II, HIPAA (with BAA), GDPR | SOC 2 Type II, HIPAA (with BAA), GDPR |
| Data retention | Follows account recording/data retention policies | Follows M365 retention policies |
Verdict: Similar privacy posture. Both explicitly state enterprise data is not used for model training. Both offer admin and user controls. The main difference is data residency — it follows whichever platform’s data residency settings apply.
Admin Deployment & Controls
| Aspect | Zoom AI Companion | Microsoft Copilot |
|---|---|---|
| Enable/disable per account | Yes — Account Settings > AI Companion | Yes — Microsoft 365 admin center |
| Enable/disable per group | Yes — Group-level policy override | Yes — via Entra group-based licensing |
| Enable/disable per user | Yes — user-level settings | Yes — per-user license assignment |
| Auto-start for all meetings | Configurable — admin can set as default on/off | Configurable — admin can set transcription as default |
| Restrict for external meetings | Yes — can disable AI Companion when external participants are present | Yes — can restrict Copilot for external meetings |
| Specific feature toggles | Yes — meeting summary, smart compose, real-time assist are separate toggles | Yes — individual Copilot features can be managed via policies |
| Audit logging | Yes — AI Companion usage logged in Zoom admin reports | Yes — Copilot usage logged in Microsoft 365 audit logs |
Verdict: Both offer granular admin controls. Zoom’s controls are simpler (web portal toggles). Microsoft’s controls use the broader M365 admin framework (policies, Entra groups, compliance center).

Which Should You Choose?
Choose Zoom AI Companion if:
- Your organization primarily uses Zoom for meetings
- You want AI meeting summaries at no additional cost
- You need phone call summaries (Zoom Phone)
- You want to avoid per-user AI licensing fees
- Your AI needs are focused on meetings and chat, not documents
Choose Microsoft Copilot if:
- Your organization primarily uses Teams for meetings
- You need AI across the full Office suite (Word, Excel, PowerPoint, Outlook)
- You’re already on Microsoft 365 E5 and the $30 add-on is within budget
- You need email AI (Outlook compose, summarize, prioritize)
- You need document generation and spreadsheet analysis
Use Both if:
- You run both Zoom and Teams meetings and need summaries in each platform
- You need Copilot’s Office productivity features and Zoom’s meeting AI
- Your sales team uses Zoom (with Revenue Accelerator) while the rest of the org uses Teams
Use Neither if:
- You’re satisfied with basic transcription and recording
- Your organization has concerns about AI processing meeting content
- Budget doesn’t allow for Copilot and you’re on Zoom’s free plan
Common Issues
- AI Companion not appearing in meetings — Verify it’s enabled in the Zoom admin portal (Account Settings > AI Companion). Check that the specific features (meeting summary, in-meeting questions) are toggled on. Some features require a paid plan.
- Copilot not available for some users — Copilot requires a per-user license assignment. Check the Microsoft 365 admin center > Billing > Licenses to verify the user has a Copilot license. Copilot is not available on E1 plans.
- Meeting summary not generated — Both systems require a minimum meeting duration (usually 3-5 minutes) and at least 2 participants. Solo test meetings won’t generate summaries.
- Concerned about privacy with AI in meetings — Both platforms display notifications when AI/transcription is active. Both state enterprise data is not used for model training. Review your organization’s AI usage policy and communicate expectations to employees.
