Follow an idea
Browse the video library. Search by mathematical concept or creator, in English or Chinese. Filters combine across fields; choices in one field are alternatives. The address stores your search and filters so you can share it.
Watch and save
Open a video for its creator and original source. YouTube, Bilibili and TikTok support embedded players; other sources show a cover and original link. Platform restrictions can prevent playback: choose Player not loading? and open the source.

Learning materials
The current catalog has completed a one-time video analysis. Reviewed materials include bilingual summaries, chapters, original educational scripts, prerequisites and knowledge cards. Scripts explain the observed mathematics rather than reproduce full source captions. Silent animations also have learning scripts.
Read the Learning script and Knowledge cards tabs, with typeset formulas. Timestamps open the player at the corresponding point where supported. Copy or export notes as Markdown. If embedding is unavailable, notes remain readable beside the original-source link. Newly submitted videos may still show a pending-analysis state. No scheduled analysis task runs.
