How to Transcribe Meeting Minutes (Mac 2026)

Which Method Should You Use for Meeting Minutes?

The right method depends on three things: how sensitive the meeting content is, how many meetings you transcribe per month, and how much you want to spend. Quick decision tree:

• Confidential meetings (legal, HR, medical, board): Record locally, transcribe with MetaWhisp on-device. Audio never leaves your Mac. Free.
• Routine internal meetings, want AI summary + action items: Otter.ai auto-join. $16.99 per month. Cloud-based.
• Occasional meetings, already on Microsoft 365: Word M365 Transcribe with the recorded audio file. Already paid for.
• Already on Zoom Pro / Google Meet Workspace / Teams Premium: Use the built-in transcript feature inside the meeting platform.

I'm Andrew Dyuzhov, solo founder of MetaWhisp. I built MetaWhisp to handle meeting transcripts privately on-device for users who can't or don't want to upload audio to cloud services. This guide covers all four paths because the right answer depends on your context — there is no single best method for every meeting.

Method 1: Record with Voice Memos, Transcribe in Microsoft Word

If you already have a Microsoft 365 subscription, this is the most integrated path. Voice Memos (built into macOS) records the meeting. Word for M365's Transcribe feature converts the audio file to a transcript inside a Word document with speaker labels and timestamps. Steps:

1. Open Voice Memos on Mac (Applications → Voice Memos)
2. Click the red record button. Voice Memos uses your default microphone — make sure it's set to capture your speakers' audio too (use BlackHole or Loopback for system audio capture on Mac)
3. Conduct your meeting. Voice Memos handles recordings up to several hours
4. Click the red square to stop. The recording saves as an .m4a file
5. Open Word for Mac (M365 subscription required)
6. Click Home → Dictate dropdown → Transcribe
7. Click Upload audio in the right pane
8. Select your Voice Memos .m4a file
9. Wait for transcription. Word's cloud-side processing typically takes 1-2× the audio length
10. Click Add to document when complete. Choose with speakers, with timestamps, or plain text

Hard limits: 300 MB per file, 5 hours of transcription per month per M365 account, per Microsoft's official Transcribe documentation. Standalone Word 2019 and Word 2021 don't have this feature — it's M365-subscription-only.

Pro tip: To capture both your voice and the meeting participants' audio on Mac, install BlackHole (free, open-source virtual audio driver). Set up a Multi-Output Device in Audio MIDI Setup that includes both your built-in mic and BlackHole, then select that device in Voice Memos. This captures both sides of the call without any special meeting platform support.

Method 2: Drop the Audio into MetaWhisp for Free On-Device Transcription

If you don't want to upload meeting audio to a cloud service — or your M365 quota is exhausted — MetaWhisp handles the same .m4a file locally on your Mac. No quota, no cap, no upload. Steps:

1. Record the meeting with Voice Memos (or any other recorder) following Method 1 steps 1-4
2. Open MetaWhisp on your Mac
3. Drag the .m4a file directly into the MetaWhisp window
4. Wait for transcription. On M2 or M3 MacBook Air, a 1-hour recording transcribes in roughly 3-7 minutes
5. Click Export in the toolbar
6. Choose format: .txt, .docx, or .srt
7. Save to your preferred location

Limits: None on file size. MetaWhisp processes audio in chunks, so a 10-hour board meeting recording transcribes the same way as a 30-minute call — just takes longer. Memory usage stays under 6 GB RAM regardless of audio duration because chunks stream through the inference pipeline. The output transcript runs through Whisper large-v3-turbo on Apple Neural Engine, the same model architecture that powers most professional transcription services. Word error rate is comparable to Amazon Transcribe and Google Cloud Speech-to-Text for clean meeting audio.

Method 3: Let Otter.ai Auto-Join Your Meetings

If you want real-time transcripts with AI summaries and action items, Otter.ai is the dominant tool for meeting capture. The auto-join feature connects Otter to your calendar (Google Calendar, Outlook, or Microsoft 365), spots meetings on your schedule, and sends a bot to join Zoom, Google Meet, or Microsoft Teams calls automatically. Setup:

1. Create an Otter account at otter.ai (free Basic, Pro $16.99/month, Business $30/seat/month)
2. Connect your calendar via OAuth in Otter's settings
3. Enable OtterPilot auto-join for the calendars you want Otter to monitor
4. Otter sends a bot to join each upcoming meeting automatically
5. The bot appears in the meeting as a participant labeled "Otter.ai"
6. After the meeting ends, Otter generates a transcript with speaker labels, AI-extracted action items, and a meeting summary
7. The transcript is searchable in Otter's web interface and shareable via link or PDF export

Strengths: Auto-join requires zero per-meeting action from you. Speaker diarization in 2-4 person calls hits 90-95% accuracy. AI summaries and action items save the manual note-taking step entirely. Weaknesses: The Otter bot is visible to all meeting participants, which may not be acceptable in confidential settings. Free tier caps at 300 minutes per month and 30 minutes per file. Pro at $204/year sits at the top of consumer-tier pricing.

For meetings where you can't have a visible third-party bot — legal depositions, HR conversations, executive sessions — Otter's auto-join isn't an option. Record locally with Voice Memos and transcribe afterward with MetaWhisp or Word.

Method 4: Use Built-in Transcripts in Zoom, Meet, or Teams

Each major meeting platform now ships its own real-time transcript feature on paid tiers. These are convenient if you already pay for the platform but each has tradeoffs.

Platform	Required tier	Storage	Speaker labels	AI summary
Zoom Cloud Recording	Pro $15.99/mo	Zoom cloud	Yes	Smart Recording add-on
Google Meet	Workspace Business Standard $14/user/mo	Google Drive	Yes	Gemini summary on Enterprise
Microsoft Teams Premium	Premium $10/user/mo on top of M365	OneDrive/SharePoint	Yes	Copilot recap

Steps vary slightly per platform but the pattern is the same:

1. Start the meeting on the platform
2. Click More → Record / Transcribe (Zoom uses "Cloud Recording"; Google Meet uses "Start transcript"; Teams uses "Start recording & transcription")
3. Conduct the meeting
4. End the meeting
5. The transcript appears in your platform's storage (Zoom cloud, Google Drive, OneDrive) within 5-30 minutes depending on the meeting length
6. Download as .vtt, .txt, or .docx depending on platform

Privacy posture: All three platforms process audio and store transcripts in the vendor's cloud. For business meetings under your IT department's existing data-handling policies, this is usually fine. For meetings under stricter compliance regimes (HIPAA, attorney-client privilege, classified content), check whether your subscription tier includes the appropriate BAA or data-residency option.

How Do I Capture Both Sides of the Conversation on Mac?

A meeting recording is only useful if you can hear all participants. Voice Memos and most third-party recorders only capture your microphone by default — the audio coming from your speakers (the other participants' voices) is not recorded. Three workarounds:

• BlackHole (free, open-source) — Creates a virtual audio device that captures system audio. Combine with your built-in microphone via Audio MIDI Setup's Multi-Output Device to capture both sides in one recording.
• Loopback by Rogue Amoeba ($109 one-time) — Same virtual audio device concept but with a polished GUI and fewer setup steps.
• Meeting platform recording — Zoom, Meet, Teams all capture both sides natively because they have access to all participants' audio streams server-side. If you can use the platform's recording feature, that's the simplest.

For one-off important meetings, BlackHole takes about 10 minutes to set up and then works permanently. The Multi-Output Device in Audio MIDI Setup (Applications → Utilities → Audio MIDI Setup) is the key configuration step — without it, your recordings will only contain your microphone.

What's the Cheapest Way to Transcribe Meetings?

Cost comparison for transcribing 4 meetings per week (about 16 hours per month of audio):

Method	Cost / month	Cost / year	Notes
MetaWhisp on-device	Free	$0	No cap, no subscription
Word M365 Transcribe	Already paid	Already paid	5-hour monthly cap may cut you off
MacWhisper one-time	—	$32 once	File transcription only, no live
Otter.ai Pro	$16.99	$204	Auto-join + AI summaries
Zoom Pro	$15.99	$192	Includes Cloud Recording
Google Meet Workspace	$14/user	$168/user	Transcript via Workspace Business
Teams Premium	$10/user (+M365)	$120/user (+M365)	Add-on to existing M365
Rev human transcription	Per-minute	$1.50/min × 60 min × 16 = $1,440	For perfect-accuracy mandates only

For most users, MetaWhisp's free on-device path covers 90% of meeting transcription needs. The paid options are worth it specifically when you need:

• Real-time captions during the meeting — only Zoom, Meet, Teams, or Otter offer this
• Auto-extracted action items — Otter and platform-side AI summaries
• Multi-speaker diarization for 5+ person meetings — Otter does this best
• Searchable shared transcript library across the team — Otter Business or Teams Premium

Will the Other Participants Know I'm Recording?

Two-party consent laws in many US states and most of the EU require that all meeting participants be informed when a meeting is being recorded. The specific rules vary by jurisdiction, per U.S. Department of Justice electronic surveillance guidance. Practical guidance:

• Announce the recording at the start of the meeting. Get verbal consent. Note it in the meeting agenda.
• Use the platform's built-in recording indicator when available. Zoom, Meet, and Teams all display a recording indicator that's visible to all participants.
• If using local recording with Voice Memos or BlackHole, there is no automatic notification — you must verbally disclose.
• Otter's bot appears in the meeting as a visible participant, which provides natural disclosure.

For internal team meetings where everyone is aware of the recording practice, the announcement step becomes routine. For external meetings (client calls, vendor negotiations, candidate interviews), explicit per-meeting consent is the safer practice.

How Do I Find Action Items in a Meeting Transcript?

Once you have the raw transcript, the next step is usually extracting decisions, action items, and follow-ups. Three options:

• Manual review — Read the transcript, highlight action items, copy to your task manager. Tedious but free and accurate.
• AI summarization with ChatGPT/Claude — Paste the transcript into your preferred LLM with a prompt like "Extract action items, decisions, and follow-ups from this meeting transcript". Costs pennies via API or use the free web UI.
• Built-in AI features — Otter.ai's AI summaries, Zoom Smart Recording, Google Meet Gemini Summary, Microsoft Copilot recap. Each platform's quality varies; Copilot recap and Otter generally produce the best action-item extraction.

For transcripts produced by MetaWhisp's on-device workflow, the AI-summarization step happens separately. Drag the transcript into ChatGPT, Claude, or your preferred LLM with a prompt that asks for structured output: action items as a bulleted list, decisions as a separate list, names of people assigned to each action item.

What File Formats Should I Use for Meeting Transcripts?

Three common formats with different strengths:

• .docx (Word) — Best for sharing with stakeholders who want to read the transcript in a familiar interface. Supports speaker labels, timestamps, comments, and tracked changes. Can be edited collaboratively in Word, Google Docs, or Pages.
• .txt (plain text) — Best for archiving and feeding to LLMs. Smallest file size. No formatting metadata. Easy to grep, search, and process programmatically.
• .vtt or .srt (subtitle formats) — Best for syncing transcripts to the original recording. Each line includes a timestamp range. Useful when you need to verify a quote against the original audio.

MetaWhisp exports all three. Otter exports .docx, .txt, .pdf, and .srt. Word M365 Transcribe exports as .docx only.
