Features
Built for real recordings
Accents, people talking over each other and music under the dialogue are handled, not just clean studio narration.
Readable line breaks
Lines are split on phrases and kept within comfortable reading speed and line length, instead of chopping sentences wherever the timer runs out.
Speaker labels
Different voices are detected and labelled, so interviews and panels stay clear about who is saying what.
Custom vocabulary
Names, brands and technical terms you provide are spelled correctly throughout, which is where generic transcription usually slips.
Translation
Create subtitle tracks in other languages from the corrected transcript, so every fix you made carries over to each translation.
Styled burned-in captions
Choose font, size, position and word highlighting for social video, with captions kept clear of on-screen text and interface overlays.
Who it’s for
Social video
Most short video is watched on mute, and captions are what keep those viewers watching to the end.
Courses and training
Make lessons accessible and searchable, and give learners a transcript they can follow along with.
Interviews and podcasts
Accurate, speaker-labelled subtitles for long conversations, with a transcript you can reuse for show notes.

Frequently asked questions
What formats can I export?
SRT and VTT subtitle files, a plain transcript, or an MP4 with captions burned into the video.
Can it translate subtitles?
Yes. Translations are made from your corrected transcript and each language exports as its own subtitle file.
How accurate is it?
Clear audio transcribes very accurately. Every line is editable before export, and custom vocabulary fixes names and jargon across the whole file.
Can I adjust the timing?
Yes. Timing follows your text edits automatically, and you can nudge any line earlier or later if a cut needs it.
Does it handle long videos?
Yes. Hour-long interviews, lectures and webinars are supported, with speaker labels kept consistent throughout.
