Synced items continue through your Apple iCloud account to iPhone, iPad, and Mac, so you can find a source from your computer when you need it on your phone. Supported content NetEase News articles are supported on recognized article pages, using the rendered title, byline, and visible article text. Hidden content, comments, and account data are excluded. On selected websites, the Safari extension supports social posts, discussions, articles, repositories, paper pages, podcast show notes, and available video text. Support depends on the site, page type, and accessible content. Video summaries use only the current video's available transcript, subtitles, timeline text, or chapters. Podcast summaries use show notes. BriefFeed does not directly analyze audio or video frames. Links that cannot be summarized can still be saved for later. Optional Notion sync Connect your own Notion integration to sync items you explicitly save in the Safari extension. The Notion token stays in that extension's local storage. Synced content goes directly from Safari to Notion, without passing through BriefFeed servers. Stay connected to the source Summary requests use the source text and limited source information needed for the summary. The extension does not send cookies or account sessions to BriefFeed. Original links remain available so you can check details and read in context.
