- Dino Hsu
- 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.

- Ryan Y
- 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
- give me heads up dexter guys :D
- KASZA_CS
- very good!
- Vindicate
- 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
- 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
- Alot of things I watch aren't available here
- J “TheSHEEEP” D
- Has recently added some shady "donate here!"-thing that pops up wildly on random websites.
- Seamus Dolan
- very poor and glitchy
- Jake
- They have implemented an annoying popup in every cart for any website i use.
- Ignacio Senra 岡

- visiteur obs

- Ken German
- Recently stopped working for Cruncyroll. The videos play really slowly (imagine 0.1x speed).
- MiguelG
- It just works
- Armando Paraiso
- not working for HBO Max :(
- Gamar Mustafa

- James Wright
- Very good extension for adding subtitles, and works everywhere too.
- Olav Aketun
- Excellent addon if you need to load your own subtitles to any video. The SRT support is great.
- Sadat Tanjim Sporsho
- good but should increase subtitles
- KC Yang (KC)
- I was told to uninstall some extensions.
- cw_gordon
- might work fine, but the 5 videos a day limit makes it pointless
- 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!!
- 痴瀚
- Awesome extension!
- Risol Jagung
- very usefull when i listening a song
- Юрий Чоба
- `Great !
- Edward De-Graft
- useful app. only issue i have is synching the subtitle. should be made easier
- 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.
- Takemi Bujin
- You can't change the position of the subtitles. It's nice that it has a sync feature though.
- Rayko Bozhurin
- It's getting error everytime when I click on the icon on Netflix.
- Ehab Eleish
- Just what i needed, Thank you!
- Kaeng Raeng
- waste of time, doesnt work
- 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.
- Karl Wolf
- Works as advertised. Thank you! Feature request: please, add the Download Subtitle button.
