About Heyday

Heyday is building an AI-powered memory assistant that makes knowledge workers smarter. We’re starting with a browser extension that helps you remember more of what you learn by resurfacing content you forgot about as you browse the web.

Samiur, our CEO who has ADHD, created Heyday to help people who have a hard time staying organized remember more of what they learn — without extra effort.
