Comments Everywhere

See Hacker News, Reddit, and X/Twitter comments for any page you visit. Icon lights up when discussions exist.

Ever wonder if the article you’re reading has been discussed on Hacker News, Reddit, or X/Twitter? Comments Everywhere checks automatically and shows you.

When you visit any page, the extension checks if that URL has been shared or discussed. If it finds results, the icon lights up and shows a badge with the total comment count. Click to read the full threaded comments without leaving your current tab.

Features:

Automatically detects discussions on Hacker News, Reddit, and X/Twitter
Badge shows total comment count at a glance
Read full threaded comments in a popup or sidebar
Search and sort comments
Right-click any link to check for discussions
Dark mode
Switch between multiple posts when a URL has been shared more than once
Hacker News and Reddit work out of the box with no setup required. X/Twitter support is optional and requires a free API Bearer token from the X Developer Portal.

This extension does not collect, store, or transmit any personal data. All API requests go directly to the respective platforms. Your browsing data never leaves your browser.
