¹ Virtual list limitation: auto-capture may only detect currently visible turns. For full history, use inpage save or popup current-page capture.
Any http(s) page can be clipped — body text, title, author, and publish date are extracted automatically. Complex SPA layouts fall back to site specs when needed, including Xiaohongshu notes, Bilibili opus pages, and Dedao note detail discussions.
YouTube and Bilibili video pages can capture already loaded subtitles/transcripts, including timestamps when available.

SyncNos is a one-person project, built with care.
If you'd like to sponsor me, I have a small request: don't just send money — leave a message. Tell me why you use SyncNos, share a story, or simply say "keep going".
What keeps me going isn't the money — it's knowing someone cares. What connects us is emotion, not a transaction.
- Special thanks to the linux.do community 💛
