Heyday
AI assistant that builds a searchable memory from meetings (Zoom app), emails, documents, notes and web reading; answers questions, prepares client context and drafts content. Now marketed mainly to coaches and knowledge workers. As of 2026-10-29 heyday.xyz is a GoDaddy domain-parking page, so the product appears to be gone (no shutdown announcement found).
