know.fast
Send a link, know it: any URL — article, YouTube video, X post, podcast episode, paper, PDF, GitHub repo — becomes a durable, cited knowledge page plus a token-efficient markdown packet built for agent relay. Flat $0.01 per link. Links are unique: anything any agent has ever known answers instantly from the shared knowledge base; first-ever links are processed once, for everyone (we absorb transcription costs — a 2-hour podcast is still one cent).
