Where to find the file
Export the audio or the full sequence first, then transcribe that file so timings match the timeline.
Steps
- Export your sequence or its audio from Premiere Pro.
- Transcribe it here and download an SRT from the Subtitles tab.
- In Premiere Pro, use File then Import to bring in the SRT.
- Drag the caption item onto the timeline above the video.
Tips
- Choose 42 characters per line and 2 lines for standard broadcast-style captions.
Menu names can change between app versions. If a step looks different, look for the closest matching option.

Which accuracy setting to choose
The speech model runs on your own device, so it is downloaded once and then saved in your browser. The app tells you the size before anything downloads, and it never downloads again unless you clear your browser data. For English, Balanced is usually enough. For most other languages, Accurate makes far fewer mistakes, and the app switches to it when you choose such a language.
| Setting | Model | One-time download | Best for |
|---|---|---|---|
| Fast | Whisper tiny | 64 MB | Quick drafts, phones, mobile data |
| Balanced | Whisper base | 136 MB | Clear speech and most everyday recordings |
| Accurate | Whisper small | 510 to 590 MB | Interviews, accents, names, most languages other than English |
| Best | Whisper large-v3-turbo | About 760 MB | Difficult audio; needs a computer with graphics acceleration |
On mobile data the app suggests Fast automatically. On a laptop with Wi-Fi, Balanced is the default and Accurate is worth the extra download if you transcribe regularly. You can switch settings at any time; each model is downloaded only the first time you use it.
Which file to download
| Format | Use it for |
|---|---|
| Word (DOCX) | Formatted transcript with speakers and optional timestamps. Opens in Word, Google Docs and Pages. |
| A fixed copy for sharing or filing. Uses your browser’s print dialog, so you can choose paper size. | |
| TXT | Plain text, with or without timestamps, for notes, email or other tools. |
| SRT and VTT | Subtitle files timed to the audio, for video editors and players. |
| Markdown | Headings and timestamps for note apps such as Obsidian and Notion. |
| CSV | One row per line with start, end, speaker and text, for spreadsheets and qualitative analysis. |
| JSON | Every segment with exact timings, for developers. |
Fixing common problems
- The file will not open
- Most audio and video formats open directly. If a file is rejected, it usually uses a codec your browser cannot decode, such as some MKV or AVI files. Open it in a free converter or in the app that recorded it and save it as MP3, M4A or MP4. The file formats page lists what opens where.
- It is slower than expected
- Speed depends on your device and the accuracy setting. Chrome and Edge on a laptop with graphics acceleration are fastest. Plug in a laptop on battery, close heavy tabs, or choose a smaller setting. Phones work, but long files are faster on a computer.
- The wrong language was detected
- Automatic detection can be misled by music or a different language at the start. Choose the language manually and run the file again.
- Repeated lines or text during silence
- Speech models can invent text during long silences or music. The app skips silent stretches and removes repeated lines, and Clean up audio helps further. If it still happens, try the Accurate setting.
- The browser ran out of memory
- Very long recordings on devices with little memory can hit the browser’s limit. Use Fast or Balanced, close other tabs, or split the recording into parts. A desktop or laptop handles several hours.
- The model download stopped
- Check your connection and try again. Model files that finished downloading are kept, so a second attempt is quicker. Once the model is saved, no connection is needed.
What happens to your recording
Your browser reads the file from your device and runs the speech model locally. The audio, the video and the transcript are never sent to a server, so there is nothing for us, or anyone else, to store, train on or lose in a breach. Finished transcripts are saved only in your browser’s storage, where you can export or delete them in your library. The only thing that comes from the internet is the speech model itself, once. You can check this by turning off Wi-Fi after the first transcript: it keeps working.
