- (2025-07-15) Gamar Mustafa: great! but cant change the playback speed with the custom player
- (2025-07-12) James Wright: Very good extension for adding subtitles, and works everywhere too.
- (2025-07-06) Olav Aketun: Excellent addon if you need to load your own subtitles to any video. The SRT support is great.
- (2025-07-05) Sadat Tanjim Sporsho: good but should increase subtitles
- (2025-07-01) KC Yang (KC): I was told to uninstall some extensions.
- (2025-06-22) cw_gordon: might work fine, but the 5 videos a day limit makes it pointless
- (2025-06-22) Lakshya Sethi: 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!!
- (2025-06-19) 痴瀚: Awesome extension!
- (2025-06-17) Risol Jagung: very usefull when i listening a song
- (2025-06-16) Юрий Чоба: `Great !
- (2025-06-10) Edward De-Graft: useful app. only issue i have is synching the subtitle. should be made easier
- (2025-06-09) Pontifex: 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.
- (2025-05-30) Takemi Bujin: You can't change the position of the subtitles. It's nice that it has a sync feature though.
- (2025-05-29) Rayko Bozhurin: It's getting error everytime when I click on the icon on Netflix.
- (2025-05-24) Ehab Eleish: Just what i needed, Thank you!
- (2025-05-21) Kaeng Raeng: waste of time, doesnt work
- (2025-05-19) Pavol Skubak: 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.
- (2025-05-19) Karl Wolf: Works as advertised. Thank you! Feature request: please, add the Download Subtitle button.
- (2025-05-16) Ahmed Mohmed: good !
- (2025-05-11) Roy Anirban: works!
- (2025-05-11) Miguel Yesan: Awesome plugin!!!
- (2025-05-10) Sasa Jovanovic: synchronization is not working
- (2025-05-09) Ravi Mattar: really cool how it does nothing
- (2025-05-08) Rich Robertson: 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
- (2025-05-08) Magician Engineering: Should add option to control the playback speed also
- (2025-04-26) jost lin: This extension is really amazing. Thank you to the developers! I hope" bilingual subtitles " can be added in the future to make it even better.
- (2025-04-25) Niroshana AngammanaMahalekam: This app is Easy to use... So Far...So Good... keep it this way or improve it... Thank You.... !
- (2025-04-24) Marko: love it
- (2025-04-21) Patrick McKeown: I only give it 4 stars because when using subtitles, they only stay in sync for a few seconds then go out of sync (only in full screen mode. Works as it should when not in full screen mode). Please fix this and any other issues with this asap. Update this extension too
- (2025-04-16) CallMeGalx: trash
- (2025-04-14) Sudarma Rathnasooriya: it really good extension to use
- (2025-04-03) Bruce Sharpe: Very nicely done and easy to use. A great way to let you apply better subtitles on YouTube, among many other things. Thanks to the dev team for making this available.
- (2025-04-03) Muatasim Algabyali: what the best time to do for the subtitles. sometimes its ahead or behind. ONE PIECE anime
- (2025-04-02) TAHA KAZEMI: It simply does its job.
- (2025-03-30) Baris Mutlu: Inability of adjusting the time offset made it pretty useless...
- (2025-03-24) Harrison: Can you add Picture in Picture? Please?
- (2025-03-23) Эльвира: does not work
- (2025-03-19) nabil samlali: BEST

- (2025-02-21) Ntkz Unlimited: It an amazing software for subtitles, greatly recommendit
- (2025-02-19) Ozangnim Studio: Gets the job done. However, I kinda wish it just finds subtitle for videos automatically.
- (2025-02-18) EnrIcH: Everything is good
- (2025-02-14) Peyman Ariamanesh: Great, every thing is ok
- (2025-02-09) Ayesha: not synced
- (2025-02-06) ŁÊGĮŤ: I think it is good but it has a major flaw that it doesn't work work long T.V series they do not have subtitles for many episodes and it is very irritating and sometimes the subtitles won't come even if there is onee they could do a lot better
- (2025-02-04) seifeddine chouki: worked great for me ....i would give 5 stars if there is an option for forcing subtitle position (up nd down)
- (2025-02-03) Agent 33: It redirects me to another website with subtitles in it. I don't want that. I just want to add subtitle in the video from the specic website.
