Website bookmarking for visual people
I founded Prism in 2019. As a designer and interweb explorer, I've always come across websites I wanted to save for future reference, but bookmark lists were useless to me because the list of links was never descriptive enough to trigger my memory of the site, so I never went back to them. The ah-ha moment came when I imagined a Pinterest-like grid and being able to see the actual site. The grid would also allow you to "browse" would make it easier to remember it and browse many sites at once.
Using a Chrome extension, you could quickly save any site you were on, and view an up-to-date screenshot of it on your board.
Though I ended up shutting down the product, going through the process of starting my own company and building an app was a challenging but highly educational experience.
