Otter vs. Microsoft 365 Copilot: Which AI Notetaker Is Better?

Sales calls run through Zoom, partner check-ins through Google Meet, internal standups through Microsoft Teams. Every one of those conversations still needs to land in the CRM before the next follow-up. That spread is exactly what an AI notetaker has to handle.

Microsoft 365 Copilot is bundled into many Microsoft 365 plans, with its meeting intelligence built for Teams. Otter.ai is an AI notetaker and Conversational Intelligence Platform that records meetings across Zoom, Google Meet, Teams, and in-person conversations, turns them into summaries with action items, and syncs the output to your external tools of choice. This comparison walks through platform coverage, CRM workflows, language support, and pricing, so you can pick the right fit for how your team actually meets.

The Short on Time Version

• Platform coverage: Otter works across Zoom, Google Meet, Teams, and in-person meetings. Copilot's meeting AI runs inside Teams only.
• Transcription and CRM sync: Otter transcribes live with real-time speaker recognition and syncs directly to Salesforce and HubSpot. Copilot ties into Microsoft 365 and requires additional setup for common CRM workflows.
• AI Chat and cross-meeting search: Otter AI Chat answers questions across your full meeting history, with MCP server access available across Otter.ai plans. Copilot's in-meeting Q&A stays scoped to the current Teams meeting and Microsoft 365 content.
• Language support: Copilot supports live caption translation in more than 40 languages, which matters most for organizations already standardized on Teams.
• Pricing: Otter offers a free plan and paid tiers with higher usage limits. Copilot is a paid add-on, commonly listed at $30 per user/month ($360 per user/year).

Why AI Notetakers Matter for Teams

AI notetakers have shifted from a personal productivity convenience to a layer of organizational memory that decides whether decisions, context, and follow-ups survive the meeting they happened. The right notetaker captures conversations as they happen and turns them into something the rest of the team can actually use.

• Every conversation becomes a searchable record. Decisions, customer context, and commitments stop living in someone's notebook or memory and start living in a system anyone on the team can query.
• Action items move out of the meeting and into the work. Follow-ups, next steps, and owners are captured in the moment, so nothing depends on who took the cleanest notes.
• Sales workflows stay current without manual entry. Call notes sync into Salesforce,HubSpot, or CRM of choice directly from the conversation, which keeps systems accurate and gives reps their time back.
• Cross-meeting intelligence surfaces patterns. Asking what objections came up last quarter or how a customer's priorities have shifted becomes a question you can answer in seconds.
• Coverage matches how teams actually meet. Notetakers that work across Zoom, Google Meet, Teams, and in-person conversations give organizations one record instead of several disconnected ones.

The value of those capabilities depends entirely on how well a given tool delivers them. That's where the comparison between Otter and Microsoft 365 Copilot starts to matter.

Microsoft 365 Copilot Overview

Microsoft 365 Copilot is an AI add-on for organizations already running on Microsoft 365 and holding meetings in Teams. It works across chats, documents, and meetings, covering Outlook email, Word documents, Excel, and more, so its productivity scope extends beyond meeting notes alone. The Microsoft 365 app was also renamed Microsoft 365 Copilot, but that app rename is separate from the paid license.

Copilot's meeting intelligence features consume the transcription generated by Microsoft Teams and layer on real-time summaries, in-meeting Q&A, action item extraction, and post-meeting recaps. Unlike Otter, Copilot does not offer custom AI summary templates.

Pros

• Live caption translation in more than 20 languages, with speech interpretation available across dozens of languages in Teams Premium
• Cross-app AI context spans chats, documents, and meetings within a single tenant
• Meeting summaries are generated automatically inside Teams

Cons

• No support for Zoom or Google Meet
• Licensing involves separate Teams, Teams Premium, and Copilot paths for different meeting features
• CRM and meeting workflow connections require more setup
• No standalone free trial for meeting AI features
• Inaccuracies in Microsoft Copilot's responses require oversight and adjustments to achieve better results

Pricing

Enterprise pricing is $30 per user per month (annual), added on top of a qualifying Microsoft 365 license.

How the Two Compare on the Features That Matter

The differences show up most clearly in five areas: cross-platform coverage, meeting search, sales workflows, language support, and pricing.

Cross-Platform Transcription and Real-Time Speaker ID

Otter transcribes live with speaker recognition happening in real time as participants talk. Copilot's meeting intelligence relies on Teams meeting content and is available only for meetings that are recorded or transcribed in Teams.

AI Chat Across Your Meeting History

Otter AI Chat lets users ask questions that span multiple meetings and get answers synthesized from those discussions. Otter's MCP server extends this further at the enterprise level, letting external AI models like Cursor and Perplexity query Otter's meeting data directly. Both tools offer in-meeting Q&A, where users can ask natural-language questions about the current Teams meeting.

Live Sales Coaching and CRM Sync

On the Enterprise plan, Otter provides live coaching, extracts buying signals via BANT and MEDDIC frameworks, syncs call notes to Salesforce and HubSpot, and drafts follow-up emails. Copilot for Sales integrates with Salesforce, LinkedIn, and Dynamics 365, and surfaces CRM data within Teams and Outlook, though those workflows require more setup than Otter's direct sync.

Language Coverage

Copilot has broader language support. Live translated captions cover more than 40 spoken languages, the Interpreter supports real-time speech-to-speech interpretation, and spoken language detection helps Teams determine which language is being used for captions and transcription. Otter supports English (US/UK), Spanish, French, and Japanese.

Pricing and Access

Otter's free Basic plan gives individuals access without an organizational commitment, and paid plans add higher transcription limits and team features. Copilot has no free tier for meeting AI.

How to Choose Between Otter and Microsoft 365 Copilot

The right choice depends on where your team already works and where your meeting data needs to land.

If Your Team Lives Entirely in Microsoft 365

For organizations that hold meetings in Teams, communicate through Outlook, and collaborate in Word and Loop, Copilot extends AI across that existing workflow. Captioning and interpretation features may also matter for multilingual meetings.

If You Meet Across Platforms and Need One Searchable Record

If your team splits meetings across multiple video platforms, or if your sales reps need call notes flowing to a CRM after every call, Otter covers those workflows from a single platform and gives you a searchable record across every conversation.

Picking the AI Notetaker That Fits Where Your Team Actually Meets

Both tools handle meeting capture and summaries well, but they fit different operating environments. The decision comes down to where your team meets and whether you want one conversation record across platforms or meeting AI that stays inside one ecosystem. That difference matters most when notes need to move into a CRM and when action items, follow-ups, and drafting all need to happen without bouncing between tools.

How One Team Uses Otter

The clearest way to see how this plays out is in the teams already using Otter day to day. At Stax, a strategy consulting firm, real-time transcription supports compressed client timelines. The team uses Otter for both in-person and virtual meetings, and Enterprise deployments save the equivalent of 1 FTE per 20 users.

Frequently Asked Questions About Otter vs. Microsoft 365 Copilot

Otterdelivers high transcription accuracy across virtual and in-person meetings, including conversations with multiple speakers. Accuracy improves further when audio is clear and when teams add custom vocabulary for industry terms, product names, or acronyms. Transcripts are fully editable, so any corrections can be made directly inside the meeting record.

Can You Use Otter With Microsoft Teams?

Yes. Otter's AI notetaker connects to Teams meetings through your calendar, transcribes in real time with speaker recognition, captures slides, and delivers a summary with action items.
