Heyday

Heyday is an AI-powered memory assistant that solves one of the most frustrating problems of modern knowledge work: you read something valuable, forget where you saw it, and can never find it again. Heyday works silently in the background, automatically saving every page you visit and building a personal knowledge base that grows with your browsing. When you search for something online or read a new article, Heyday resurfaces relevant content you've already seen — appearing right alongside your search results, as article overlays, or in your searchable knowledge base. It's like having a second brain that remembers everything you've ever read, always ready to connect the dots when you need it most.
