Not just text — a transcript that jumps back to the video
Every line has a timestamp for audio playback; meeting recordings can also identify speakers.

I've finished pulling this week's numbers — retention is up on last month.
00:19Speaker 2
What's day-one retention now?
00:23Speaker 1
Around 41%, three points up. Mostly from the onboarding change.

So could we move the onboarding step even earlier?

Features
The parts that actually save you time
A two-hour recording is not hard because it is long. It is hard because you have to find things in it.
Local audio and video
Upload MP3, M4A, WAV, MP4 or MOV and get a timestamped transcript.
Speaker labels
We work out how many people are talking and label them. Rename them if you like.
Click to seek
Every line links back to the exact moment, so checking never means scrubbing.
Long audio
Anything over an hour is chunked and stitched, so it will not fail halfway.
Export anywhere
TXT, SRT, VTT, Markdown and JSON. Subtitles drop straight into a player or editor.

FAQ
Things you might be wondering
Something missing? Email us.
Which files are supported?
Upload local audio or video such as MP3, M4A, WAV, MP4 and MOV.
Do I need an account to extract captions?
Yes. Choose a file and sign in. Meeting recordings require you to confirm speaker settings; subtitle extraction resumes automatically.
What if the video has no captions?
Yes. Upload a local video and speech recognition will generate subtitles.
Can I play the uploaded file?
You can play the audio on the result page and seek using subtitle timestamps.
What formats can I export?
SRT, VTT, TXT and Markdown, plus a plain-text copy with or without timestamps.
How long do uploads stay?
Audio is cleaned up on a schedule under our privacy policy, and you can delete it yourself from the workspace.
Is transcribing someone else’s video allowed?
Only process content you have the right to use — you own it, you are licensed to, or it falls under fair use. We act on takedown notices.
