Desk No. 03 · Meeting summarizer
The best AI meeting summarizer
Compared on a 47-minute scripted team meeting reference, April 2026.
For most knowledge workers, Otter Pro or Fireflies Pro at the low-to-mid monthly tier is the right buy. Both handle Zoom, Teams, Meet, and offline recordings, producing meeting notes with owner-tagged action items. Free options: Otter Basic (300 min/mo) or Microsoft Teams Copilot if you already have an M365 Copilot licence. Enterprise: Copilot inside Microsoft, Duet AI inside Google Workspace.
§ I.The reference scenario
The reference scenario used for side-by-side comparison on this page is a scripted 47-minute team meeting covering a product roadmap discussion, a customer escalation update, and sprint planning for the following two weeks. The meeting has five participants, two of whom speak only briefly, and includes three action items explicitly assigned by name and four implicit follow-ups mentioned but not formally assigned. It is a useful reference because it contains the failure modes meeting summarizers most commonly trip on: speaker diarization with quiet participants, owner-tagged action items, and implicit follow-ups.
The reader-applicable rubric covers: transcription word error rate (2 points), summary completeness (2 points), explicit action items captured with owner tags (2 points), implicit follow-ups identified (1.5 points), speaker diarization accuracy (1.5 points), and integration / delivery speed (1 point). Total: 10 points. Full rubric at /methodology. Apply it to a meeting you actually need summarised on whichever tool you are evaluating.

! When to skip all of them
If your meetings are legally privileged (attorney-client discussions, HR investigations, board-confidential strategy sessions), use enterprise-tenant tools only: Microsoft Copilot with Purview, Zoom AI Companion on an enterprise tier with data processing agreements in place, or do not use AI meeting summarization at all. Consumer tools like Otter and Fireflies are not appropriate for genuinely privileged conversations regardless of their stated privacy policies.
§ V.Common questions
Q.01Can AI summarize a Zoom meeting?
Yes. Three approaches work in April 2026. First, Zoom AI Companion (native): if your host has Zoom Pro, Business, or Enterprise with AI Companion enabled, it automatically generates meeting summaries and action items without any additional setup or bot. Second, bot-join tools: Otter Pro or Fireflies Pro join as a bot participant, record and transcribe independently, then email you a summary. Third, tl;dv offers a free bot-join option. Recording consent rules apply regardless of method.
Q.02Is Otter HIPAA compliant?
Otter.ai does not offer a standard Business Associate Agreement (BAA) on its consumer plans. For HIPAA-regulated use cases (recording patient conversations, clinical team huddles involving patient data), Otter is not appropriate without a specific enterprise arrangement. Enterprise-grade alternatives for HIPAA-sensitive meeting summarization include Microsoft Teams Copilot with Purview (within a compliant M365 tenant) or Zoom's healthcare-specific HIPAA-compliant tier with AI Companion disabled unless specifically reviewed.
Q.03What is the difference between Otter and Fireflies?
Otter's primary strength is transcription accuracy and a clean meeting notes interface. Fireflies' primary strength is CRM auto-logging (it integrates directly with Salesforce, HubSpot, Pipedrive and pushes call summaries and action items automatically) and speaker-tagged soundbite clips. For knowledge workers needing clean notes, Otter is the better experience. For sales teams that need call data flowing into a CRM without manual entry, Fireflies wins. Both handle Zoom, Teams, and Google Meet via bot join.
Q.04Does Teams have a built-in meeting summarizer?
Yes, Microsoft Teams Copilot provides Intelligent Recap: a post-meeting feature that generates chapter breakdowns, action items, speaker-attributed highlights, and integrates with Microsoft Planner for task assignment. It requires a Microsoft 365 Copilot licence in addition to your existing M365 subscription. It runs entirely within your Microsoft tenant, which is a significant advantage for organizations with data residency or confidentiality requirements.
Q.05Can I summarize a meeting without recording it?
Bot-join tools like Otter and Fireflies join as a participant and create their own transcript even if the official host recording is off. This means you do not need host permissions to capture a transcript via a bot. However, this raises consent considerations: most jurisdictions require all-party consent for recording conversations. Always inform participants that a bot is present and capturing the meeting. Zoom, Teams, and Google Meet all surface visual indicators when a bot has joined.
Q.06Are meeting bots legal?
In most all-party-consent jurisdictions (California, many EU member states), you must inform all participants before recording, whether via a platform feature or a third-party bot. The bot's visible presence in the participant list counts as notice in most platforms' terms, but this is not guaranteed legal protection in all jurisdictions. For meetings involving non-employees (clients, candidates, patients), check your counsel's advice before deploying any AI recording tool. For internal-only meetings with standing consent policies, bot-join tools are widely used without issue.
