Professional online tools for media localization : instant access from anywhere, any time, any operating system

Create, edit and translate captions, subtitles and scripts in any language online, using a simple and intuitive web interface, without downloading anything to your local workstation. State-of-the-art tools with frame-accurate streaming allow for timed-text control with an advanced timeline, video grid for precise caption positioning on the screen, audio waveform and scene-change detection for accurate subtitle spotting, as well as many other features subtitlers have come to love.

Powerful Pro apps enable QA scripts to automatically check and fix your files, as well as customize hotkeys and project settings. Our tools feature import and export in almost any caption and subtitle format, including TTML/DFXP, VTT, SCC, CAP, EBU-STL, SRT, IMSC, PAC, 890 and many more.
