Submarine

What is Submarine?

Submarine is a native Mac app for finding and downloading subtitles for video files. It is made by Bitfield AB and is designed for people who watch local movies and want a quick way to locate matching subtitles without searching websites manually. You can drag a movie file onto the app to look up subtitles online, or run a manual search when you want more control over the results. Subtitles can then be downloaded for use with your video files, and the app also integrates with other Bitfield media tools for related subtitle workflows. Submarine is focused on a simple utility role rather than full video playback or editing, making it useful as a lightweight helper in a Mac media library.

Key features

• Find subtitles online for local movie files
• Search in your preferred subtitle language
• Drag and drop a video file to start a subtitle lookup
• Download matching subtitles for later use
• Search manually when you want more control over results
• Send subtitles directly to compatible Bitfield apps

Safety overview

Status: Safe

Submarine is a legitimate Mac utility for subtitle lookup and download. Access to files you open with the app is normal for its purpose, since it needs movie information to search for matching subtitles. If you remove it, you may lose a convenient way to fetch subtitles, but it should not affect macOS itself. As with any subtitle source, review downloaded files and keep the app updated through its normal distribution channel.

Recommendation: Keep Submarine if you regularly add subtitles to local video files or use other Bitfield media apps in the same workflow. If you no longer search for subtitles on your Mac, you can remove it without affecting the rest of macOS.
