BriefFeed: AI Summaries for Social Feeds by BriefFeed

Compact summaries beside loaded content, a local bookmark library for worthwhile sources, and AI Insights when you ask.

About this extension

BriefFeed is a desktop Firefox reading assistant that helps you understand loaded content without losing the original source. It places compact AI summaries beside supported social posts, discussions, articles, project pages, podcast Show Notes, and available current-video transcript, subtitle, timeline, or chapter text.

Save worthwhile sources to a local bookmark library, then create a source-linked AI Insights brief when you choose. BriefFeed summarizes only supported content already loaded in the browser. It does not auto-scroll or paginate feeds, read cookies or passwords, collect private messages, or call social-feed APIs to obtain more posts.

Supported surfaces include X/Twitter, Bluesky, Jike, Weibo, Reddit, V2EX, Hacker News, Lobsters, GitHub, Product Hunt, YouTube, Bilibili, WeChat Official Accounts, Substack, Medium, WordPress, DEV Community, arXiv, OpenReview, Apple Podcasts, Xiaoyuzhou, and opened Xiaohongshu note details. Named supported sites use required access; supported custom article domains ask for exact-site access when you enable them.

Optional Notion and NotebookLM exports are initiated or enabled by the user and go directly from Firefox to the chosen service. BriefFeed is free to use.

An optional reading workspace brings together bookmarks, local browsing-history search, and source-linked Insights. It is off by default. Open it from the extension menu after enabling it in Settings. A separate, default-off Firefox option opens the bundled BriefFeed workspace automatically in native new tabs. Turn it off at any time; private tabs, blank pages, and other extensions’ new-tab pages remain unchanged.
