Caption X - Windows is a CEP extension for Adobe Premiere Pro that handles transcription and caption generation without leaving the timeline. It covers 57+ languages, including right-to-left scripts such as Arabic, Hebrew, Urdu, and Persian, and produces styled, presentation-ready output that needs no manual formatting. As the name indicates, this build runs on Windows; installed on macOS, the panel shows an "Unsupported OS" message.
Captions can be generated from any audio track in your sequence, with adjustable line length across short, medium, and long options. Finished captions export as an SRT sidecar file or burn directly into your render. The workflow removes external tools, copy-pasting, and manual formatting steps.
Caption X requires an active subscription, with a free plan available, and you sign in inside the panel to get started. It suits video editors, content creators, and post-production teams working with multilingual content or delivering subtitles across several languages, from social and short-form video to documentary, corporate, and educational projects.
