Frequently asked questions
Do I have to upload my video?
No. You point it at a YouTube link; the video plays from YouTube and your captions are built and stored locally in your browser.
Can I subtitle a video that isn't mine?
You can caption any YouTube video for things like language practice or fan subs. Respect the original creator's rights when you publish or share the result.
Is there a time limit on the video?
Short and medium videos are free. Very long videos are a Pro feature.
