What you get

SRT and VTT, ready to use

The two formats every video player, social platform and editing tool accepts.

Timed to the speech

Every line starts and ends with what is being said, so captions never run ahead or lag behind.

Readable lines

Lines break at natural pauses and stay short enough to read comfortably on screen.

Long videos

Up to an hour per file, in every common audio and video format.

Check before you publish

Play the recording with the transcript beside it and see the less certain words underlined.

Reviewed by a person

For broadcast, education or public-sector work, have captions checked by a reviewer before delivery.

How do reviewed captions work?
A person checks and corrects the captions before they are delivered. Pricing and turnaround depend on the volume and the language — talk to us for a quote.
