Remember more with no extra effort

See forgotten content alongside search results

You waste 20 minutes looking for an article you read in the past, but you can't find it and your best ideas never develop. Heyday automatically saves pages you visit and resurfaces them alongside search results.

Heyday saves me a bunch of time and mental energy during my research process by helping me remember content and work from the past I’ve totally forgotten.

People who do a lot of research love Heyday

As someone with a sloppy brain who spends a lot of time on the internet, Heyday's ability to organize everything for me is a life-saver.

I love that it passively combs my history and contextualizes for me. In my case, I look at a lot of papers, and I'm always going, "where did I see that?" With Heyday I can quickly find it.

I’m a long-time sufferer of ‘i read something once that said X’ then could never find the article again. Heyday fixes that and makes it easy to collate topics without having to manually tag every page.

Patrick Tomasiewicz

Comms Strategy, Anomaly

As part of my day job I go through 100s of websites every day and have to revisit many of them. Heyday has been a savior for me by surfacing the websites at the right time and right context.

I've been using Heyday for a few months and it has done an exceptional job helping me resurface content without having to worry about saving, bookmarking, or keeping tabs open. Which is amazing, because I've been a chronic and incorrigible tabhog for years.

Heyday hasn't just made me feel smarter, pretty sure it's made me smarter, or at least made future me smarter.

Erik Martin

Vice President of Services, Commsor

If I had one productivity tool to use for the rest of my days, and you made me get rid of all my others, I would be fine using Heyday.

Emily Weltman

Founder, Collective Flow Publishing

Heyday just works. I highly recommend it for anyone who has 100+ browser tabs open, is drowning in sticky notes (digital or otherwise), or needs to keep track of research information over time.

As a product person and founder at a startup, I'm constantly reading up on our problem space and customers. Heyday ties it all together.

The beauty of Heyday is that it works seamlessly alongside you without being annoying. When you go looking for it, it's loaded with incredibly useful content that makes life easier, smarter, and just downright enjoyable.

Jack Cohen

Vice President, FirstMark Capital

Heyday is a great product for creators and knowledge workers alike. It basically functions as an extension of my memory that's searchable, shareable & easily manipulated.

Kyle O'Brien

Founder, Startup ROI

Heyday was an easy sell: effortless bookmarks and contextual serendipity. I switched over from MyMind and haven't looked back.

Lorenzo Santos

Product Manager, ConsenSys/MetaMask

Slick! Particularly in the age of information overload when we forget what we read so fast. Love the resurfacing part - repetition makes the game.
