Live Captions for Meetings on Mac: Built-In vs a Saved Transcript

You want live captions for meetings on your Mac for one of a few very concrete reasons: you’re hard of hearing or in a loud place; the call has accents, jargon, or numbers you can’t afford to mishear; or English isn’t your first language and reading along doubles your comprehension. And in almost every one of those cases you have a second requirement you discover about five minutes after the first: you need the text to still exist when the meeting ends.

That second requirement is where the built-in options quietly fail. macOS has a genuinely good real-time captioning feature, and every major meeting platform has some form of captions — but nearly all of them treat the text as disposable. This post walks through the three ways to get live captions on a Mac, what each one actually saves, and how to get real-time text that becomes a permanent, searchable transcript.

Option 1: macOS Live Captions (built-in, saves nothing)

Apple ships a system-wide captioning feature as part of macOS accessibility. Turn it on and a floating panel captions whatever your Mac is playing — a Zoom call, a Teams meeting, a browser tab running Google Meet, a podcast — plus your own mic if you enable it.

To turn it on: System Settings → Accessibility → Live Captions, then toggle it on and pick your language. In macOS 26, Apple expanded Live Captions to around 11 languages, including English variants, Spanish, French, German, Japanese, Korean, and Chinese, and the captions run on the same on-device speech engine generation that powers the system’s other transcription features. Processing happens on your Mac — nothing is sent to a server, and it works offline.

For pure in-the-moment comprehension, it’s hard to beat: free, already installed, works with every app because it captions system audio rather than integrating with anything.

The hard limit: nothing is saved. The panel shows a rolling window of recent text, and when the audio stops, the captions are gone. There’s no transcript view, no save button, no export, no history. If someone read out a phone number forty minutes ago, it has left the building. macOS Live Captions is an accessibility overlay, not a note-taking tool, and Apple built it that way deliberately.

Use it when you need captions for something you’ll never need to reference — a webinar you’re half-watching, a video without subtitles. For meetings you’re accountable for, it’s half a solution.

Option 2: the meeting platform’s own captions

Every major platform has captions, each with its own catch:

• Zoom offers automated captions in-meeting; depending on the account’s settings, the host may need to enable them before participants can switch them on. The live captions themselves aren’t saved for you — a saved transcript is generally tied to recording features on paid plans. The full landscape is covered in how to transcribe Zoom meetings on a Mac without a bot.
• Microsoft Teams has live captions that are explicitly ephemeral — they aren’t retained after the meeting. Saved transcription is a separate feature governed by org policy, and the AI-generated Intelligent Recap requires a Teams Premium or Copilot license for each person who views it, not per attendee.
• Google Meet has free built-in captions, and they’re good — but they vanish at the end of the call. Saved transcripts and recordings are gated to Workspace Business Standard and up, and are cloud-processed. Details in Google Meet transcription on a Mac.
• Webex captions come via its AI Assistant features, which are tied to paid Suite and Enterprise plans; the free tier caps meetings at 40 minutes.

Notice the pattern: real-time captions are increasingly free, but the saved transcript is the upsell, gated behind the platform’s paid tier — and when you do pay, the transcript is processed and stored in that platform’s cloud, lives in the host’s account rather than yours, and covers only meetings on that one platform. If your week spans Zoom, Meet, and a couple of Slack huddles, you’d need three subscriptions and three places to search.

Option 3: live transcript that’s yours to keep

Dictanta approaches the problem from the recording side: capture the meeting’s audio on your Mac, transcribe it live as it plays, and keep everything. You get the real-time text and the permanent record from one press of record.

Here’s the workflow:

1. When the call starts, press ⇧⌘R. Dictanta’s source picker offers three options: My voice (mic only), This meeting (the auto-detected meeting app’s audio plus your mic), or Another app (the frontmost app’s audio plus your mic). Zoom, Teams, Webex, and Slack are auto-detected, and Meet is covered through the browser — Safari, Chrome, Arc, Brave, Firefox, or Edge.
2. Pick “This meeting.” Capture runs through ScreenCaptureKit, scoped to the meeting app’s process — macOS files this under the Screen & System Audio Recording permission, and it’s audio only, never video, never a pixel of your screen. No bot joins the call and nothing changes for the other participants. (More on the mechanics in how to record system audio on a Mac.)
3. The transcript streams live in the Dictanta window while people talk — both sides of the call, readable in real time, exactly the “live captions” half of the problem. It’s powered by Apple’s SpeechAnalyzer running on-device on your Apple silicon; in MacStories’ independent testing (June 2025), that engine ran roughly 55% faster than Whisper Large V3 Turbo. If the language model isn’t on your Mac yet, macOS fetches it once, and transcription then runs fully offline.
4. When you stop, the text doesn’t evaporate. The full transcript is saved (it was autosaving every 30 seconds all along, so even a crash mid-call recovers it), and Apple Foundation Models generate an on-device summary: TL;DR, action items with owners and due dates, decisions, and open questions. Summary lines that show a timecode are audio-anchored — hover one and playback jumps to the moment it came from.

Afterward, the meeting is searchable in-app and via Spotlight, and exports to Markdown, PDF, Word, SRT, or JSON. Nothing was sent to a server: audio, transcription, and summarization all happen on your hardware, and the audio never leaves the device. Transcripts and summaries sync to your iPhone and iPad through your own private iCloud database.

One honest caveat: Dictanta’s live transcript lives in the Dictanta window, not in a floating overlay on top of your meeting app. On a single screen you’ll want the windows side by side; macOS Live Captions is the better pure overlay. The trade is that Dictanta’s text persists and Apple’s doesn’t.

The three options at a glance

Which one should you actually use?

Use macOS Live Captions when you need an overlay on audio you’ll never reference again — videos, webinars you’re auditing, a call where you’re a spectator. It’s free, private, and always available.

Use the platform’s captions when you’re a participant with no stake in the record — someone else owns the meeting and its notes, and you just want to read along.

Use Dictanta when the meeting is one you’re accountable for: client calls, interviews, standups where the action items are yours to chase. The live transcript covers the in-the-moment need, and the saved, on-device transcript plus summary covers everything after. Requirements: macOS 26.4 on Apple silicon (M1 or later) — and on iPhone and iPad (iOS/iPadOS 26.4), one-tap mic recording shows the same live captions for in-person meetings, with a Live Activity in the Dynamic Island. Dictanta needs Apple Intelligence turned on (iPhone 15 Pro or later; an iPad with M1 or A17 Pro or later, or a Mac with M1 or later).

These aren’t mutually exclusive, either. Plenty of Dictanta users keep macOS Live Captions on as the overlay during the call and let Dictanta produce the record — both run on-device, so the only cost is screen space.

Bottom line

Live captions for meetings on a Mac are a solved problem in real time and an unsolved one the moment the call ends: macOS Live Captions and the platforms’ built-in captions all discard the text you just read. If the words matter past the meeting, capture them once, properly — a live on-device transcript that’s saved, searchable, summarized, and exportable, with no bot in the call and no cloud in the loop. Dictanta’s first 3 recordings are free with every feature unlocked; caption one real meeting with it and check whether you ever open the ephemeral kind again.

FAQ

Can macOS Live Captions save a transcript of a meeting?

No. macOS Live Captions is an accessibility feature that displays real-time captions for system and mic audio, but the text is ephemeral — when the audio stops, the captions are gone. There is no save button and no export. To keep a transcript, you need a tool that records and transcribes the meeting, such as Dictanta, which captures the meeting app’s audio on-device and saves a full searchable transcript.

How do I get live captions for a Zoom or Teams meeting on a Mac?

Three ways. Turn on the platform’s own captions (Zoom and Teams both offer them in-meeting, though they typically aren’t saved for you). Turn on macOS Live Captions in System Settings under Accessibility, which captions any system audio but saves nothing. Or record the meeting with Dictanta, which streams a live transcript while the call runs and keeps it afterward, along with an on-device summary.

Do live captions on a Mac work offline?

Yes, both options do. macOS Live Captions processes audio on-device. Dictanta also transcribes on-device using Apple’s SpeechAnalyzer — macOS fetches the language model once if it’s missing, and transcription then runs fully offline, with the transcript saved and searchable afterward.
