More of what you read, from posts to long reads
BriefFeed goes beyond social feeds. It distills loaded posts and discussions, long-form articles and newsletters, papers and product pages, podcast Show Notes, and available video transcripts or captions—so you can quickly decide what deserves a deeper read. AI Insights brings together today’s supported loaded content, including same-day history received from your other devices when browser-history sync is enabled.

Summaries stay attached to loaded posts, details, visible media, and thread context. Xiaohongshu runs only on a note detail you explicitly open.

- Substack Native *.substack.com articles with visible title, byline, and body. Custom domains require explicit per-site enablement.
- Medium Native medium.com and *.medium.com articles with visible title, byline, and body. Custom domains require explicit per-site enablement.

- WeChat Opened mp.weixin.qq.com article pages after enough visible body text loads.
- Zhihu Zhihu articles and opened individual answer pages. Each summary covers that answer, with the question as context; it does not combine all answers. Uses only rendered text, without bypassing collapsed, login-gated, or paid content.
- NetEase News 163.com article pages, based on loaded visible body text.
Podcast Show Notes and available video transcript/subtitle text are treated as source text, not audio or video analysis.
- Podcast Show Notes Apple Podcasts and Xiaoyuzhou episode pages, based on visible Show Notes only.

- GitHub Repository pages, substantial profile READMEs, public Sponsors profiles, the home feed, and Trending surfaces.
- Product Hunt Opened product/launch pages and long visible comments already rendered in the page.

No account handoff, no hidden-content scraping
BriefFeed is designed as a browser assistant for content already loaded in the current page.
- No BriefFeed account is required.
- Requests include only source id or URL, author display label, timestamp, visible text and bounded source emphasis, platform, detected language, and optional visible link metadata.
- Raw source bodies are not logged and are not persisted longer than needed for the current cache and summary request.
- External sync is optional; Notion tokens stay in this browser, and NotebookLM uses the current browser's Google session without storing Google cookies or frontend tokens.
Frequently asked questions
How is BriefFeed different from pasting a link into an AI chat?
BriefFeed places compact summaries beside supported posts and pages while you browse, so you can decide what deserves a closer read before saving it. Saved sources keep their original links, and AI Insights connects its points to source cards. An AI chat is useful for a conversation about a chosen source; BriefFeed focuses on reading in context and finding useful sources again.
How can I turn my reading into material for further research?
Start with a summary on a supported page, save the sources worth revisiting, and use AI Insights to synthesize supported loaded content with links back to its sources. You can optionally send selected saved items or saved Insights briefs from the browser to Notion or experimental NotebookLM sync for follow-up work. Saving a source does not create a full-article archive.
Can I organize my saved items into categories?
Custom tags are coming soon. You'll be able to create tags, apply them to one or multiple saved items, and browse by tag, with tags syncing across devices. Until then, you can use the desktop browser extension to sync selected saved items to Notion and organize them there.
Do the browser extensions and Apple apps have the same role?
The desktop browser extensions add summaries to supported loaded pages. On iPhone and iPad, you can share a supported public link to BriefFeed. The Apple apps provide a saved-source library and reading workspace; optional sync connects your reading across devices. Supported surfaces and features vary by client and version. There is no Android app.
Is BriefFeed free?
BriefFeed is currently free to download. This is not a promise of permanent free access or unlimited use. Check the store listing for your device for the current download price.
How do I try my first summary?
Install the extension for your browser and open X. Sign in to X if needed, then open a substantive English post from an author you follow. Allow site access if prompted and look for the summary beside the original. Short or unsupported pages may not show a summary. On iPhone or iPad, you can also share a supported public link to BriefFeed. Start with one source before setting up optional sync.
Are summaries generated entirely on my device?
Hosted summarization sends bounded source text and source metadata to BriefFeed’s service and its configured AI providers. It is not an entirely on-device workflow. It does not send your site passwords or session cookies. The privacy policy explains processing, caches, and optional sync in detail.
Where can I use BriefFeed?
BriefFeed is available for Chrome, Microsoft Edge, and Firefox, with apps for iPhone, iPad, and Mac. See the download options above for store links.
Which reading surfaces are supported?
Inline summaries support selected social post surfaces plus selected discussion, new product, project, article, research-paper, podcast Show Notes, and current-video YouTube/Bilibili transcript, subtitle, timeline, or chapter text, including opened Xiaohongshu note details, Apple Podcasts and Xiaoyuzhou episodes, WeChat, DEV Community, Zhihu articles and individual answers, and NetEase News articles, arXiv abstract and HTML paper pages, public OpenReview paper pages, and native or user-enabled custom-domain Substack, Medium, and WordPress articles, where the relevant content has already loaded in the browser. On X, Bluesky, Jike, Weibo, Reddit, and V2EX, supported loaded surfaces can be summarized in foreground or background tabs before entering your view and can be included in AI Insights; Xiaohongshu runs only on a note detail the user opens.
How does external sync work?
External sync is optional. Notion uses your configured token and data source, while experimental NotebookLM sync uses the current browser's Google session and selected notebook. Notion is for a structured saved-source library; NotebookLM turns chosen saved items or Insights briefs into sources for follow-up research. These payloads are sent directly from this browser and are not routed through BriefFeed servers.
Do I need a BriefFeed account?
No. You can use BriefFeed without creating a BriefFeed account.
Does BriefFeed replace the original feed?
No. It adds a compact summary layer above posts already loaded in the current page. You can still inspect the original post in place.
Does the extension collect cookies or passwords?
No. BriefFeed does not read, store, or send social account passwords, cookies, session tokens, or login credentials to BriefFeed servers.
