How to Get Live Captions for Zoom Recordings in Chrome (2026)

Do Chrome live captions work on Zoom recordings?

Yes. Chrome's built-in Live Caption works on Zoom cloud recordings played in a browser tab at zoom.us, because the recording is standard web video audio that Chrome's caption engine can access.

To confirm: Chrome's Live Caption does NOT work on the Zoom desktop app — it only works on audio playing inside a Chrome browser tab. If your professor shared a Zoom recording link that opens in your browser at a zoom.us URL, Chrome's captions work. If the recording opens the Zoom app on your computer, Chrome's captions don't apply.

LessonScriptor works on any video playing inside a Chrome tab — including Zoom recordings at zoom.us, Zoom recordings embedded in Canvas, Moodle, or Blackboard, and MP4 files played in Chrome directly.

What is the difference between Zoom's transcript and Chrome live captions for recordings?

Zoom's built-in audio transcript is a pre-generated text file that Zoom creates by processing the recording after the meeting ends. The host must have enabled 'Cloud recording' with 'Audio transcript' before the meeting — if they didn't, no transcript is available.

Chrome live captions and LessonScriptor are real-time transcription tools that generate captions as the video plays, independently of whether Zoom generated a transcript. They transcribe the actual audio from the recording, not a pre-generated file.

Zoom's built-in transcript: Available only if the host enabled it. Appears as a separate panel on zoom.us. Can be downloaded as VTT or TXT. Speaker-labeled. Only available in English for most account types.

Chrome's built-in Live Caption on a Zoom recording: Read-only caption bubble that appears as the video plays. Disappears when the video ends. Cannot be saved or exported. Works in any language Chrome supports.

LessonScriptor on a Zoom recording: Real-time transcript in a side panel. Fully editable, exportable as Markdown or plain text. Works in 14 languages. Available whether or not Zoom generated a transcript. Can be annotated with highlights and notes.

How do I get a transcript of a Zoom recording in Chrome?

To get a transcript of a Zoom recording in Chrome using LessonScriptor:

1. Install LessonScriptor from the Chrome Web Store. Free, no account required.
2. Open the Zoom recording in Chrome. This works at zoom.us/rec/play/[recording-link], in Canvas (click the Zoom recording link in your LMS), or by dragging an MP4 file into Chrome.
3. Click the LessonScriptor icon in your Chrome toolbar to open the side panel.
4. Switch to 'Tab audio' mode in the LessonScriptor panel if you're using headphones (Premium feature). Leave it on 'Microphone' mode for the free tier.
5. Press play on the Zoom recording. LessonScriptor starts transcribing immediately. The transcript appears in the side panel in real time.
6. Edit the transcript as it generates — correct names, technical terms, or misheared words by clicking directly on the text.
7. When the recording ends, click 'Export' to save the transcript as Markdown or copy it to your clipboard.

Do live captions work on Zoom recordings embedded in Canvas?

Yes. Zoom recordings embedded in Canvas (Instructure's LMS) are typically hosted on zoom.us or on Kaltura and played back inside a Chrome iframe within the Canvas page. LessonScriptor's tab audio capture works on these embedded videos because it accesses the audio stream at the tab level — the iframe embedding doesn't affect this.

Chrome's built-in Live Caption also works on Canvas-embedded Zoom recordings, with the same limitation: the transcript is read-only and disappears when the video ends.

Other LMS platforms (Moodle, Blackboard, Brightspace) use similar video embedding approaches and are also compatible with LessonScriptor.

If your Canvas-embedded Zoom recording doesn't play audio at all, that's usually a browser permission issue — check that Chrome hasn't blocked autoplay audio for your university's Canvas domain.

Can I get captions for a downloaded Zoom MP4 file in Chrome?

Yes. If you have a Zoom recording saved as an MP4 file on your computer, you can transcribe it with LessonScriptor by playing it in Chrome.

How to do it: 1. Drag the MP4 file into a new Chrome tab, or type `file:///` in the address bar and navigate to the file. 2. Chrome will play the MP4 file in a native video player. 3. Open LessonScriptor's side panel and start transcribing as normal.

Note: For downloaded MP4 files, LessonScriptor's free mode (microphone-based) will transcribe the audio as it plays through your speakers. If you're using headphones, you'll need to either play the audio through speakers briefly, use Windows or macOS system audio capture, or upgrade to LessonScriptor's tab audio capture (Premium) which captures audio before it reaches any output device.

Should I use Zoom's transcript feature or LessonScriptor?

Use Zoom's built-in transcript when it's available and you only need a static text copy of the recording. Zoom's transcript is speaker-labeled, which is useful for multi-speaker meetings where knowing who said what matters.

Use LessonScriptor when Zoom's transcript isn't available (the host didn't enable it), when you need to edit and annotate the transcript, when you're watching from Canvas or another LMS, or when you need to export formatted notes rather than a raw text dump.

For academic use, LessonScriptor's edit-as-you-watch workflow is more useful than Zoom's transcript for most students. Zoom's transcript requires waiting for processing after the recording — LessonScriptor generates the transcript as you watch, letting you annotate in real time.
