How to Add Captions & Subtitles to a Loom Video

June 16, 2026

If you want to add captions to a Loom video, you are making one of the highest-impact edits possible. Studies consistently show that roughly 85% of social and feed video is watched on mute, so without on-screen text most viewers never hear a word you recorded. Captions also make your content accessible to deaf and hard-of-hearing viewers, help non-native speakers follow along, and boost comprehension and watch time for everyone. As a bonus, the transcript behind your Loom subtitles gives search engines real text to index, which helps your videos surface in results. The good news: there are several free and paid ways to add captions, and at least one of them is fully automatic.

Below we cover Loom’s built-in captions, the manual SRT/VTT route, and the fastest option — ScreenStory’s automatic word-level karaoke captions that sync perfectly to an AI voiceover.

Loom’s Built-In Captions & Transcript

Loom automatically generates a transcript and closed captions for recordings on many of its plans. When the transcript is ready, viewers can toggle the CC button in the player to show captions, and you can open the transcript panel to read or copy the full text.

To enable or check captions on a Loom video:

  1. Open the video in Loom and wait for processing to finish — the transcript usually appears a minute or two after upload.
  2. Click the Transcript tab beside the video to confirm text was generated.
  3. Press the CC icon in the player controls to turn captions on for viewers.
  4. Edit obvious transcription errors directly in the transcript panel if your plan allows it.

The limitations matter. Loom’s captions are display-only: they live in the player, so anyone watching outside Loom (in a presentation, on social media, or in a downloaded file) sees nothing. Styling is minimal, you cannot brand the captions, accuracy varies with audio quality and accents, and there is no word-level highlighting. If you need captions that travel with the file, you will need another method.

Adding Captions Manually (SRT/VTT)

The traditional approach is to create a subtitle file — an SRT or VTT — and attach or burn it in with a video editor. This works, but it takes effort.

  1. Download the video. Follow our guide on how to download a Loom video to get the MP4 file.
  2. Transcribe it. Run the file through an auto-transcription tool, or export Loom’s existing transcript, to produce timed text.
  3. Build the SRT. Format the text into numbered cues with start and end timestamps. Most transcription tools can export SRT directly.
  4. Attach or burn in. Upload the SRT alongside the video on a platform like YouTube (which accepts SRT uploads), or import both into a desktop editor and burn the captions permanently into the frame.

This route is free, but it is fiddly: you are juggling files, fixing timing drift, and styling captions by hand. For a single short clip it is fine. For regular content it becomes a chore — which is why automatic word-level captions exist.

Automatic Word-Level Captions with ScreenStory

ScreenStory removes the manual work entirely. It imports your Loom recording, rewrites the script for clarity, generates a natural AI voiceover, and produces word-level karaoke captions that highlight each word exactly as it is spoken — perfectly synced because the captions are built from the same narration. You then export a polished MP4 with the captions burned in. Here is the workflow:

  1. Copy your Loom share link. In Loom, set the video to public sharing and copy the link — ScreenStory imports from public Loom links only.
  2. Paste it into ScreenStory. The link is downloaded and processed automatically; no file wrangling on your end.
  3. Let the AI do the work. ScreenStory analyzes the screen, rewrites a tighter script, generates a realistic voiceover (with an optional talking avatar), and creates word-level captions synced to that narration.
  4. Review and tweak. Edit the script, caption text, voice, or timing in the browser. See our guides on editing a Loom video and adding a voiceover to a Loom video for more.
  5. Export. Render a finished MP4 with captions burned in, ready for any platform. ScreenStory runs in your browser on H100 GPUs, so exports are fast.

Because the captions are generated from the AI narration rather than guessed from messy original audio, accuracy is excellent and the karaoke highlighting lands on the right word every time. It is the recommended option if you want professional captions without touching a subtitle file — and it is part of turning a raw clip into something you can ship, as covered in making a Loom video professional.

Open vs Closed Captions & Styling

There are two kinds of captions, and the difference decides where your text shows up.

For social media, presentations, and watch-on-mute scenarios, burned-in captions win because they always appear. Styling matters too: font, size, color, and position can be tuned to match your brand and stay readable over busy screen recordings. Word-level highlighting (karaoke style) adds a modern, engaging feel that flat subtitle blocks lack.

Frequently Asked Questions

Does Loom have automatic captions?

Yes. Loom auto-generates a transcript and closed captions for recordings on many of its plans, viewable via the CC button. However, those captions are display-only inside Loom’s player and are not burned into the file, so they disappear when the video is downloaded or shared elsewhere.

How do I add subtitles to a Loom video for free?

The free manual route is to download the video, auto-transcribe it into an SRT file, and upload that SRT to a platform like YouTube that accepts subtitle files. It works but requires fixing timing and styling by hand. ScreenStory offers a free trial if you want automatic captions without the manual steps.

Can I burn captions into a Loom video?

Loom itself does not burn captions into the file. To get permanent, burned-in (open) captions, either import an SRT into a video editor and re-render, or paste your public Loom link into ScreenStory and export an MP4 with word-level captions baked in.

Can I add captions in another language?

Yes. ScreenStory supports 15+ languages, so you can generate a voiceover and matching captions in the language your audience speaks. This is especially useful for reaching non-native viewers or localizing the same recording for multiple markets.

Why are word-level captions better than block subtitles?

Word-level (karaoke) captions highlight each word as it is spoken, which improves focus, comprehension, and engagement compared with static blocks of text. Because ScreenStory builds them from the same AI narration, the timing is exact rather than estimated.
