How it works
One iOS share action becomes a knowledge card.
OmniSift is built for ideas that appear outside your notes app: AI answers, web paragraphs, chat messages, screenshots, and saved links.
AI distills the snippet
Cloud AI extracts a title, summary, highlights, tags, named entities, and semantic relations.
云端 AI 自动提炼标题、摘要、高亮、标签、实体和语义关系。
Review and connect
Browse your library, search saved cards, and revisit ideas through a growing personal knowledge graph.
回到知识库中浏览、搜索，并通过个人知识图谱重新发现关联。
Positioning
Not another place to type notes.
OmniSift starts where ideas actually show up: inside ChatGPT, Claude, Safari, WeChat, X, Notes, and screenshots. It focuses on capture, structure, and recall.
OmniSift is an iOS AI knowledge capture app. It lets users save text, links, articles, and screenshots from any app through the iOS Share Sheet, then turns them into structured knowledge cards. Cards are stored locally on device. No account is required.
知漏是一款 iOS AI 知识捕获应用。用户可以通过系统分享菜单，从任意 App 保存文本、链接、文章和截图；知漏会将这些碎片整理成结构化知识卡片。卡片保存在设备本地，无需注册账号。
Privacy boundary
Local-first storage, clear cloud processing.
OmniSift does not claim fully local AI. Text you share is sent to cloud AI for processing, and the resulting cards are stored on your device.
No account required
Start collecting without sign-in, onboarding accounts, or a hosted workspace.
No tracking
OmniSift does not use analytics services, advertising frameworks, or behavioral tracking.
Local card storage
Processed knowledge cards are stored locally on device. Text is sent to cloud AI only for processing.
