Local-first capture for AI conversations, web articles, and useful video-page context.

Captured content is stored locally before optional sync or export. External providers and exported files are derived copies, not the primary record. See Privacy for permissions, credentials, and network data flows.

The optional syncnos CLI lets AI agents work with a running SyncNos browser profile. Install it from npm, enable Settings → CLI & AI SKILL → Local CLI Integration → SyncNos CLI in that profile, and keep the browser running while the agent uses it.
npm install -g @chiimagnus/syncnos@latest
syncnos install
syncnos doctorSee CLI & AI SKILL for setup. AI-agent Skills ship in skills/syncnos/ (English) and skills/syncnos-zh/ (中文).
Alongside the popup and in-page entry points, SyncNos provides browser-native shortcuts to open the popup, save the current page, and open/focus the SyncNos app. No keys are assigned by default; use Settings → Keyboard shortcuts to see the browser's current bindings. See Capture.
Supported: ChatGPT, Gemini, Google AI Studio, DeepSeek, Kimi, Doubao, Yuanbao, Poe, Notion AI, and z.ai.
ChatGPT and Google AI Studio require manual capture because their virtualized conversation lists cannot be treated as complete automatically. Other supported AI chat collectors can auto-save when AI auto-save is enabled.
ChatGPT uses DOM capture by default and also offers an optional Advanced API path for manual current-conversation capture. See Capture content for behavior and limitations.
Any ordinary http(s) page can be captured manually. SyncNos extracts readable content and relevant metadata, with site-specific handling where needed. Captured articles support local comments and highlight-only annotations.
SyncNos supports YouTube watch/youtu.be pages and Bilibili BV playback pages, including Watch Later playback with a valid bvid. It saves available page context and already-loaded subtitles/transcripts; Bilibili chapters/highlights are also kept when the current player provides them. SyncNos does not download the audio/video stream, and a supported video remains a Video even when no subtitles are available yet.
