User reviews

HyperChat is praised for enhancing YouTube live chat by improving performance, reducing memory leaks, and providing a better interface, making live chats usable on older hardware. However, users want easier reply features, better translation support, and advanced filtering options. Some have reported issues with recent updates affecting translation features, and the add-on's branding may be too prominent for some.

Pros

Significantly improves YouTube live chat performance and reduces memory usage, especially on less powerful devices and non-Chromium browsers.
Provides a custom chat interface that is easier to follow, including features useful for watching multi-language streams with translation comments.
Makes YouTube live chat usable on older or less capable hardware like tablets and older laptops.
Fixes memory leaks associated with YouTube's default live chat, enhancing browser stability.

Cons

Lacks easier methods to respond to other chatters (e.g., auto-mentioning).
Translation feature has stopped working in recent updates for some users.
Desires for more advanced chat filtering options, such as filtering comments by language, are unfulfilled.
Branding on the chat interface can be visually obtrusive for some users.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

HyperChat [Improved YouTube Chat] requires a few sensitive permissions. Exercise caution before installing.
