How do I quickly summarize a long Bilibili lecture?

Paste a Bilibili link and the system transcribes the audio and generates timestamped chapter notes and a mindmap, so a multi-hour lecture takes minutes to skim, with timestamps to jump back.

Does it support Bilibili collections / multi-part videos?

It processes a single public video link; for collections or multi-part videos, paste each part's link separately. Only public content with reliably resolvable audio is handled.

Can Bilibili videos without captions be summarized?

Yes. It doesn't rely on uploader captions — it transcribes the audio, so voice-only knowledge videos work too.

Can the summary export to Notion / Obsidian?

Yes. The body exports to Markdown and the mindmap to .mmd / .svg, syncing straight into linked-note apps.

How long does a two-hour Bilibili video take?

It depends on audio length and queue load; two-hour content usually lands in the tens-of-minutes range, with stage progress shown so you can leave and return.

How is summarization billed?

Credits are charged by media length; see the pricing page. You can try a link on the free allowance first.
