For Demon Slayer, I found one .SRT file for one episode only, Substital allows only upload one file at a time, this is too tedious.
perfect
perfectly working ,loved it..
five stars
Would be perfect if the subtitle position could be moved.
Perfectly working
it's so but not even working
so good
very good
nice❤️
ok
It was supposed to just add subtitles, but the developer sneaked in a donation feature on random websites (even though it wasn’t for themselves).
give me heads up dexter guys :D
very good!
You can find the subtitiles you want but you can only try 5 of them in 24 hours. And ofc, 90% of them are not synchronised.
I use it for local servers. It can't detect the video in them. So i have to separately download subtitles. But then it works great, so yeah recommended
Alot of things I watch aren't available here
Has recently added some shady "donate here!"-thing that pops up wildly on random websites.
very poor and glitchy
They have implemented an annoying popup in every cart for any website i use.
Very useful and easy to use
ITS AMAZING WORKS PERFECTLY NOT A BOT
brave
Recently stopped working for Cruncyroll. The videos play really slowly (imagine 0.1x speed).
It just works
not working for HBO Max :(
great! but cant change the playback speed with the custom player
Very good extension for adding subtitles, and works everywhere too.
Excellent addon if you need to load your own subtitles to any video. The SRT support is great.
good but should increase subtitles
I was told to uninstall some extensions.
might work fine, but the 5 videos a day limit makes it pointless
Not just the popular websites it works even for a lot of unknown players! And it integrates so well that it seems like it is part of the player!!
Awesome extension!
very usefull when i listening a song
`Great !
useful app. only issue i have is synching the subtitle. should be made easier
Please add a speed control, or make it sense the video speed. If it's paused or skipped forward/backward it syncs, but it assumes the video is at 1x speed when playing.
You can't change the position of the subtitles. It's nice that it has a sync feature though.
It's getting error everytime when I click on the icon on Netflix.
Just what i needed, Thank you!
waste of time, doesnt work
More-less it works, however, it's somewhat cumbersome. The largest issue is that there is no way to position the subtitles, so when I want to use dual subtitles (for language learning), they happen to exactly overlap. A few other glitches too. A pity since most of the work is well done, but the last polishing touches are missing.
Works as advertised. Thank you! Feature request: please, add the Download Subtitle button.
good !
works!
Awesome plugin!!!
synchronization is not working
really cool how it does nothing
I absolutely love this app. An extremely hard of hearing individual, it makes finding subtitles for videos on any page workable. Some of the sites I use for videos don't have subtitles or when watching English dubbed animes, they don't have the English subtitles but I can use this for that. I do however wish that it had an option to delete histories and pass searches as well as an easier method for syncing subtitles to videos such as the timing. The little drag box or having to type in tweaks it's kind of finicky. Other than that, this app is perfect!!!! 5 Stars
