Siftube — YouTube 主题过滤与专注模式

按关键词或主题过滤 YouTube，只看你想看的内容。可保存学习、工作等多种配置。完全本地，保护隐私。

Curate your own YouTube without the algorithm fighting back. Siftube filters YouTube based on keywords you choose. Tell it what you want to see, or what you do not want, and it hides everything else from your homepage, search results, watch-page sidebar, and Subscriptions. Filtering happens instantly and locally in your browser. What makes Siftube different: - Exact match: fast, literal, predictable. - Smart match: recognizes word forms, so cook finds cooks, cooking, and cooked. - Topic match: uses Chrome's on-device AI when available, then falls back to local Smart matching if unavailable. Profiles for every context: - Study mode for educational content. - Work mode to reduce distractions during focus hours. - Weekend mode for lighter filtering. - Spoiler-free mode to hide videos about shows or games you have not finished. Built for real YouTube use: - Filter homepage, search results, watch-page sidebar, and Subscriptions. - Whitelist mode to show only matches, or blacklist mode to hide matches. - Block channels with one right-click on any video card. - Always-show overrides for channels you trust. - Filter log shows what was hidden and why. - Hide the Shorts shelf with a toggle. - Available in English and Simplified Chinese. Privacy promise: - All filtering happens in your browser. - No tracking, no analytics, no accounts, no network calls. - Keywords and profiles are stored locally and may sync only through your own Chrome account. Minimal permissions. No webRequest, no ad blocking, and no network blocking. Siftube simply hides videos you do not want to see.
