Latest reviews

  • (2023-10-17) Dylan Murphy: I love everything this extension does but there is just 1 thing that makes me keep it disabled most of the time. And that is the inability to click my own message to see that I am able to remove it which also confirms that it actually went through. The reason is so many streamers block a lot of random words from chat and many times a completely normal or respectable comment will not go through and you wont even know it. The only way to check is to click on your message and if it shows you are able to remove it then you know it went through and did not get silently censored. It is also the way to check if you are muted/banned from chat or not, since YouTube doesn't notify users when they've been muted from chat. Add this ability and I will change the rating to 5 stars.
  • (2022-12-26) Saipaet: Translator [TH} not working please update😢ັ
  • (2022-11-16) pocapele: Review for version 2.6.8 It fixed but still buggy. Sometimes not active by default, must disable-enable Hyperchat. Rating increase to 4 stars. Review for version 2.3.1 Still not fixed. Review for version 2.3.0 Good update for translation but it translate wrong. I choose English but they translate Indonesian. Same with other languages. I'll change the review if the problem fixed. For now, it's okay.
  • (2022-10-12) 小光尼リーロン: 請問如何單獨放大聊天室的文字,字太小了 how to zoom live chat ? font size too small
  • (2022-10-10) Bryce Pirie: the extension works, for at least the " top chat ", the live chat however it does not. - when in live chat mode, no messages show up. please fix this bug, i can't use this extension unless i can fully use the chat.
  • (2022-09-03) ゆげ: スパチャステッカーのせいでカクカクだったyoutube liveのチャット欄が軽くなりました。スパチャの多い配信を見るなら絶対入れるべきアドオンです。 チャット欄上部に残るスパチャステッカーだけでなく、チャンネルアイコン、メンバーバッジ、絵文字のみのスパムチャットを消してすっきり見やすくできます。全画面表示の時はチャット欄の枠や文字の大きさを調整できますし、チャットの背景を半透明化してopenrecのチャット欄みたいにすることもできます。
  • (2022-08-22) F S: YouTube Sticky Live Chat等、他のスクリプトや拡張機能と併用出来ない スパナコメントを固定出来る設定が無い
  • (2022-08-01) Bloody Erin: Was working perfectly before but now, auto-translate won't work no matter what I do. Too bad... Edit: My one star review was truly unfair to the devs so changed it back to 5 stars. Hope it'll work in thee future like before
  • (2022-07-19) Gray: Really useful, with lots of features and customization options
  • (2022-03-12) L: Finally, an extension that stopped YouTube live streams from lagging. The chat is so clean and the donations don't take up the whole chat. I would wish for an option to see deleted messages in the chat, like in BTTV.
  • (2022-03-06) Rolan Stunkart: 完美,CPU占用降低了至少一半。 -------------------------------------------------------------- perfect,I love it。
  • (2022-02-21) Ebb “and” Flow: Almost perfect, the problem is.... choosing english translation doesn't work, it keep translating into Indonesian language for some reason ( I can speak Indonesia so it was not a deal breaker). Hopefully this issues is fixed in near future. I tried it on mozzile firefox and the problem persist.
  • (2022-02-13) Davide Ciappeddu: Works as intended, but the only issues is there a slight delay to when messages sent show up in chat. Other than that it's a great extension and definitely recommended.
  • (2022-02-04) Christian T.: Great extension, can really help with performance of YT streams!
  • (2022-02-03) Sami: Drops CPU usage definetly. Customisation is also available for avatar picture showing, timestamps etc. if you like to still see those in chat. Very good.
  • (2022-02-01) Calvin Hou: Works as intended
  • (2022-01-27) J J: Very nice extension. The latest update (at the time of writing this) of adding the settings was very nice. Hopefully there will be an option to display the superchat/membership bar and font customization (because live chat font is very small imo) in the future. Thank you and keep up the good work!
  • (2022-01-27) Ginseng: Amazing -- clearly the reviews show that people don't know where to find the extension settings, since most of the things people complain about can be customized in settings. My only issue is the ~2 second delay in sending messages, but it's still worth it to be able to watch streams without stuttering thanks to CPU overflow. I understand that it's probably an API limitation, but I would love to see less message-sending delay, and the ability to superchat etc. from the Hyperchat box. Great extension overall; keep up the good work!
  • (2022-01-17) 浮生若夢: Better than other extensions and script on tampermonkey No more lagged when watching streaming now Even when opening dozens more of streaming tabs at the same time The Only lose was the speed at which chat room messages are displayed , but not really serious
  • (2022-01-14) Jhazat: It did indeed heavily reduce CPU usage of the chat like it said, at the cost of making everything else about it considerably worse, with at the time I downloaded it, no way I could find to change any options anywhere. It definitely has potential if I could actually customize anything about it, but with a simple TamperMonkey script to hide the SC bar you basically get the same amount of CPU reduction with no loss in features compared to this extension that removes all function for only form.
  • (2022-01-10) moyu: good
  • (2021-12-22) スーパーグルタミンココア: あんなに重かったコメント欄が嘘みたいに軽くなりました!ありがとうございます!!!
  • (2021-12-19) 054林聿珩: 解決了聊天室造成整個分頁當機的問題,現在可以開著聊天室看直播了。
  • (2021-12-13) An Huỳnh: good one
  • (2021-12-12) Wolfsblvt: Great extension, really helped me during streams with like what, 100k concurrent viewers? Thanks to this, I didn't even crash once. Gura outfit reveal saved.
  • (2021-12-11) Bear Pooh (Paradox85AR): 8.5-10% down to 4-5% on R7-1700 really works
  • (2021-11-22) Zee K: Reduce the ridiculous CPU usage by youtube chat.
  • (2021-11-01) Weerawat Seesoda: Work great
  • (2021-10-14) Kasie [桐生会]: Chat are slow, but help a lot on CPU load.
  • (2021-10-04) Dramorian: The usage of CPU is lowered, but the most stupid thing — random chat freezing — still persists.
  • (2021-10-01) Chanathip Sup.: THE BEST
  • (2021-09-21) Lunatics Danem: works as intended
  • (2021-08-28) Claire Crowles: I like the extension because it makes the live chat bearable (which usually lags even on my pc despite it being quite a powerful pc), but as another reviewer said, the messages in the chat (yours and others') appear very late. I'm guessing this is to reduce CPU usage too, but it's really frustrating to be even 6-10 messages late compared to the streamer and the whole chat.
  • (2021-08-25) Nelson Herman: chat like speed
  • (2021-07-31) Hans Ramos: Perfect for users like me who would even give up the live chat just to barely watch streams, but want to interact with the stream in some way. Although if you're not okay with no avatars in live chat and other live chat features either completely disabled or downgraded in some way, this may not be the extension for you.
  • (2021-07-01) Lijo: Super smooth. Great UI
  • (2021-06-25) Harold Tsang: the Chat are too slow
  • (2021-05-31) Hernani Roy Roxas: It does what it claims to do very well, and made live chat bearable to open on my toaster laptop. However, it doesn't seem very polished, I can live without seeing the avatars, but the message sending delay is really painful. The alternating backgrounds do increase readability and I liked that, however you can't see superchats for some reason. It needs a bit more tweaks, but it really does optimize the live chat, just keep in mind the few concessions in doing so.
  • (2021-05-29) Jonah Hohlfeld: Very nice extension the only things I would really want is showing pinned comments at the top, and being able to show superchats pinned to the top.
  • (2021-05-27) Антон Савельев: This extension fully changes how youtube chat looks, and all changes seem to be for the worst: - Removes avatars - Makes the text smaller and less readable - Adds alternating black and gray background to messages which is a good intention, but the gray is too bright, vibrates with green usernames and adds too much visual clutter and impairs readability - Chat messages are misaligned vertically within their background boxes, either up or down, always off center - Pressing chat function buttons such as "toggle timestamps" breaks the functionality outright. - Most important: No options to tweak the visual presentation of the chat. tldr very poor presentation and a direct visual downgrade to the original chat. I cannot in good conscience recommend this extension to anyone.
  • (2021-05-23) ЅeeD: Nice extensions but i can't see my own messages in the YouTube Live Chat after i send them. I cant find links in chat to copy and paste back in chat or messages i want to delete.
  • (2021-05-22) Adib Hadee: Very noticeable change, thanks you for extension!!
  • (2021-05-11) Jan Gihr: As others have said already, way better performance than regular chat, but sadly no superchats on top (yet?). Would love this as an option.
  • (2021-05-07) Nik: Very nice extension, but as people said above, would be nice to collect and show hyperchat messages somewhere. And maybe messages from verified YouTubers too? They are hard to catch live but I'd love to read them easily :) +1 for adding multiple styles too! Ideally there should be an "original youtube" style where basically everything stays the same (fonts, colors, sizes, etc) and only CPU usage is optimized.
  • (2021-05-06) Priere: The only thing I wanted to add is the superchat like in regular. Everything else is freaking flawless though.
  • (2021-04-26) Des: Much better than the default chat.
  • (2021-04-15) Brown: Works very well, but the UI could do with some tweaking, the usernames look really bad in bold especially with Japanese characters.
  • (2021-03-28) Robert Volante: Does exactly what it says on the box, reduces CPU usage of my Ryzen 3600 by literally about 15% when active. Only thing I'd love is a little bit more customization options (colors, text size), and maybe an option to display older Superchat messages on top like regular chat. Looking forward to future versions!
  • (2021-03-15) TheZyiu [ザージュー]: It needs some adjustments here and there but it really is useful. My CPU agreeds
  • (2021-03-14) Fahmi Fahrizal: Works like a charm! This really makes my CPU usage way lower than the normal CPU usage when watching a youtube livestream

Latest issues

  • (2023-01-24, v:2.6.8) BANNED4LIFE: Some messages not coming through
    Everything has worked fine for me for a while, but I recently noticed something that may have been happening all along. Some messages simply don't come through with HC enabled even in Live Chat mode. Only way I was able to tell is a streamer was reading every message in a stream and was reading ones I couldn't see so I disabled HC and there was the messages I didn't see before and when I reenabled HC then I could still see them. Maybe happening when messages come through at the same time? Idk, kinda annoying tho and makes me not want to use it if im missing messages.
  • (2022-12-04, v:2.6.8) Richard Ralston: Showing messages from blocked users
    HC is not blocking messages from blocked users. Switched between HC and normal chat to confirm. Regular chat the user's messages were being blocked but switching to HC that users messages were coming through. Is it a bug on my end or an issue?
  • (2022-08-22, v:2.6.5) pocapele: Error translation
    Version 2.6.5 still error in translation. I choose English, the translation is Indonesian.
  • (2022-08-09, v:2.6.4) とげぱん: long text filter
    I think it would be an even better tool if a long text filter was added!
  • (2022-04-19, v:2.5.2) Blood Sand: Perhaps an option to show deleted messages
    • See deleted messages like betterttv has for twitch.
  • (2021-12-08, v:2.0.1) 鳥丼饂飩: Could you make S.C. bar back?
    Or make it optional, I kind like that thing. Really helpful extension for me, thanks. Sorry for my bad English.
  • (2021-08-29, v:1.3.4) Justice Seeker: Work with Deepl translate
    Any chance HyperChat could be modified to work with Chat Translator for Deepl (https://chrome.google.com/webstore/detail/chat-translator-for-deepl/fbmkdedikbcbkkeaofpenfncppepfnlo)? Thanks.
  • (2021-06-13, v:1.1.0) tinday: Username color doesn't change
    Username color doesn't change in youtube chat but does when chat is open through other sites like holodex or holotool.
  • (2021-03-14, v:1.0.10) Serouzo Lee: Is it possible that spam messages get picked up?
    So I'm watching Coco's stream who has set her chat to members-only mode and I know that the feature to distinguish members and admins in chat is available where members' names are green admins are yellow. However, I noticed that a lot of messages come in where the names are white. At first I thought it was a bug where some members appear as white in chat but by reading some of the messages I could tell they were spam from antis. I don't know how this extension works in the backend but is it possible that spam messages are being picked up through whatever API you are using? Possibly spam messages that somehow are being sent through some other API regardless of the members-only filter and still picked up by Youtube?
  • (2021-03-09, v:1.0.8) Антон Савельев: Alternating message background colors,
    Good day and thanks for your work! I am using the version bundled with LiveTL. I feel that for youtube's dark theme, the alternating black/gray backgrounds of chat messages are way too contrasting. Please consider making the gray background darker, or giving the user control over precise background color. Also, it seems that the text size is smaller than youtube's default, which compromises readability. Also, as I'm using the LiveTL bundled version, as of now Hyperchat conveys no information whatsoever to the user as of what exactly it does, which I found highly confusing. Thanks in advance.
