WebM is what a browser saves when a web app records you without installing anything: VP9 video with Opus sound, or Opus alone when only the microphone was captured. Upload either kind and download the transcript as a genuine .docx. Your first transcript costs nothing and is readable in full at any length · packs begin at $8 per 1,000 minutes.
How it works
Whatever your player does with the file, the words come out the same.
Drop in the file the web app downloaded to you. It makes no difference whether it has a video track or is microphone audio alone.
Lines are timed from the audio itself, so they are right even when a media player shows no duration at all for the file.
Take the Word document with or without timestamps. SRT and VTT come from the same transcript if the recording needs captions.
About WebM
Convenient to make, occasionally strange to play back.
Web meeting recorders, browser screen recorders, in-page dictation tools and research platforms all use what the browser provides, and that is WebM.
A WebM written live by a browser often records no duration, so players show a blank or endless timeline and refuse to seek. The audio is intact, and the transcript here carries proper times.
Microphone-only capture runs about 20 to 30 MB an hour. A 1080p browser screen recording is nearer 300 MB to 1 GB an hour, which still leaves room under the ceiling.
A video track changes nothing about the result. Only the sound is read, and the Word file is identical either way.
| WebM recording | One hour | Three hours | Ten hours |
|---|---|---|---|
| Microphone only, Opus | ~25 MB | ~75 MB | ~250 MB |
| 720p screen capture | ~250 MB | ~750 MB | ~2.5 GB |
| 1080p screen capture | ~700 MB | ~2.1 GB | Near the 5 GB limit |
Browser encoders vary, so treat these as a guide. Over 500 MB, start from the upload page.
Common uses
Nothing was installed, and nothing needs installing now.
A call recorded by a browser tool becomes written notes, which is what anyone who missed it will read.
Screen plus voice is the standard research recording; observations are drawn from the document.
A colleague sends a five-minute recording instead of a meeting. Reading it takes one.
Speak a draft into a web tool, then edit the Word file rather than retyping what you said.
Pricing
A screen recording and a microphone-only capture of the same meeting cost the same, because only running time is counted. One free transcript, in full, covers a recording of up to 3 hours.
A 25-minute stand-up recorded in a browser is $0.20 on the $8 pack. Doing that daily for a year is roughly 6,250 minutes, a little over one $24 pack. Pricing lists the packs.
FAQ
Yes. Drop in the file the web app saved for you, with or without a video track, and export DOCX once the transcript is ready.
Almost certainly not. Browsers often write these files without a duration, so players cannot scrub them. The audio is complete and the transcript is timed correctly.
No. Speaker labels are shown in the transcript view here, beside each line. The DOCX export contains the words, and JSON is the export with speaker information in it.
Yes. A microphone-only recording with no video track uploads the same way and produces the same document.
Up to 5 GB, and up to ten hours. Screen recordings at 1080p approach that size around seven or eight hours.
Yes. SRT and VTT export from the same transcript without spending further minutes, and their timings match the recording.
Yes, a real .docx and not a renamed rich text file, so it opens and edits in Word, Google Docs, Pages and LibreOffice.
No, only what was said aloud. Anything you demonstrated silently leaves nothing in the transcript.
Instant preview, no signup. Timed correctly even when your player is not.
