Hey guys,
I created https://u-boat.io in my spare hours. You can use it to easily download subtitles in batch, simply by selecting the video file(s) from your hard disk. What would take you 20 to an hour to do manually on the OS website, you can now do in 20 seconds.
Please let me know what you think! I am in super beta phase. As in...I did not even do extensive cross-browser testing. Viewing it in IE is therefore not recommended.
Hope it can be of use to any of you. Comments for improvements would be greatly appreciated.
