ok

Ryan Y 2025-09-01

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).

Kənan Zeynalov 2025-08-29

give me heads up dexter guys :D

KASZA_CS 2025-08-24

very good!

Vindicate 2025-08-16

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.

Fabiha 2025-08-16

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

Arwa Hosny 2025-08-16

Alot of things I watch aren't available here

J “TheSHEEEP” D 2025-08-11

Has recently added some shady "donate here!"-thing that pops up wildly on random websites.

Seamus Dolan 2025-08-10

very poor and glitchy

Jake 2025-08-07

They have implemented an annoying popup in every cart for any website i use.

Ignacio Senra 岡 2025-08-05

Very useful and easy to use

Ken German 2025-07-27

Recently stopped working for Cruncyroll. The videos play really slowly (imagine 0.1x speed).

MiguelG 2025-07-22

It just works

Armando Paraiso 2025-07-21

not working for HBO Max :(

Gamar Mustafa 2025-07-15

great! but cant change the playback speed with the custom player

James Wright 2025-07-12

Very good extension for adding subtitles, and works everywhere too.

Olav Aketun 2025-07-06

Excellent addon if you need to load your own subtitles to any video. The SRT support is great.

Sadat Tanjim Sporsho 2025-07-05

good but should increase subtitles

KC Yang (KC) 2025-07-01

I was told to uninstall some extensions.

cw_gordon 2025-06-22

might work fine, but the 5 videos a day limit makes it pointless

Lakshya Sethi 2025-06-22

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!!

痴瀚 2025-06-19

Awesome extension!

Risol Jagung 2025-06-17

very usefull when i listening a song

Юрий Чоба 2025-06-16

`Great !

Edward De-Graft 2025-06-10

useful app. only issue i have is synching the subtitle. should be made easier

Pontifex 2025-06-09

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.

Takemi Bujin 2025-05-30

You can't change the position of the subtitles. It's nice that it has a sync feature though.

Rayko Bozhurin 2025-05-29

It's getting error everytime when I click on the icon on Netflix.

Ehab Eleish 2025-05-24

Just what i needed, Thank you!

Kaeng Raeng 2025-05-21

waste of time, doesnt work

Pavol Skubak 2025-05-19

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.

Karl Wolf 2025-05-19

Works as advertised. Thank you! Feature request: please, add the Download Subtitle button.

Ahmed Mohmed 2025-05-16

good !

Roy Anirban 2025-05-11

works!

Miguel Yesan 2025-05-11

Awesome plugin!!!

Sasa Jovanovic 2025-05-10

synchronization is not working

Ravi Mattar 2025-05-09

really cool how it does nothing

Rich Robertson 2025-05-08

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

Magician Engineering 2025-05-08

Should add option to control the playback speed also
