> Keep YouTube captions on or off across videos. Detect burned-in subtitles locally and handle duplicate captions your way with subtitle.im for Chrome.

It is a Chrome extension for YouTube. It manages YouTube captions that you can switch on or off. Other sites, mobile browsers and local video files are outside its current scope.

Click CC in the YouTube player to turn off switchable captions. Burned-in subtitles are part of the video image, so CC cannot remove them. subtitle.im detects these subtitles and handles duplicate captions according to your settings. A manual CC change stops automatic adjustment for this viewing without changing saved rules.

In Caption control, choose Follow YouTube, Auto-open, or Auto-close. Follow stops proactive opening; duplicate handling still uses its separate settings. Auto-open needs an existing track. Auto-close turns off switchable captions without detection or duplicate-handling charges. Manual CC/C changes win over video, channel, and global settings for this viewing; manually opened captions stay on. Reloading or opening another video restores the rules. Burned-in subtitles remain; no captions are generated or translated.

With enough evidence of burned-in subtitles in another language, it follows your choice: close automatically, ask first or keep the switchable captions. Choose keep if you want both languages visible.

It can generally detect most clear, common burned-in subtitles, though misses and false positives can occur. Low resolution, unusual placement or complex lettering can reduce accuracy. When evidence is insufficient it keeps switchable captions; if they are hidden by mistake, undo from the prompt or turn YouTube CC back on.

Recognizes text in your browser without uploading frames. No email needed for the free trial.

Video rules override channel rules, which override global settings.

Remembering confirmed closes requires Pro.
