按内容语义搜索书签与收藏，而非只靠标题

来源证据

创建者因刻意保存的帖子和视频分散在四个应用、无法一起搜索而构建产品；现有书签只是 URL 和标题，不含内容，无法支持按内容查找。

Hey Product Hunt! I built Deepmark because I kept losing things I'd deliberately saved. Not forgotten: saved. A thread about pricing, a reel with a cooking trick, a talk someone linked me. Four apps, four lists, and none of them searchable together, because a bookmark is a URL and a title and nothing else. Deepmark indexes what's actually inside a save. Pages get fetched and read. Videos and reels get transcribed. A few frames per video get described and OCR'd, and every page gets a screenshot
