## Description

HyperChat is a powerful Chrome extension designed to improve your YouTube livestream chat experience. It offers advanced CPU and RAM optimizations including memory leak patches and a custom-built message renderer, ensuring smoother performance during active chats.

The extension provides extensive customization options such as light and dark themes, toggling of profile icons, timestamps, usernames, badges, mentions, and emojis. Users can also enable features like sticky superchats and system-native emoji rendering for a pleasant visual experience. Quality-of-life enhancements include Google Translate integration for messages, filtering member-only messages, skipping emoji-only messages, and automatic switching to "Live Chat" mode.

Compatible with other popular chat extensions like LiveTL and YtcFilter, HyperChat is free, open source, and maintained by the same developers behind LiveTL. It is the ultimate tool to optimize and customize YouTube livestream chats for any user.

## Review summary

Users consistently praise HyperChat for major performance gains (fixing memory leaks) and for making live chat usable on low-end devices via a faster, custom chat interface with a live-chat default. The most common complaint is the absence of advanced chat filters (language filters). Several reviewers also request additional UX features and subtler branding.

### Pros

- Significantly improves chat performance and fixes memory leaks, reducing browser resource use
- Makes YouTube live chat usable on low-end devices, tablets, and older laptops
- Replaces YouTube's chat with a faster, custom interface
- Option to switch to live chat by default and better handling of translation/’live’ translation messages

### Cons

- Lacks advanced chat filters (e.g., language-specific filters) — frequently requested
- Missing some desired UX features and polish (easier reply workflow, subtler branding); users want more customization
