Heyday

Heyday is a Chrome extension that helps you retain more of what you learn while browsing the internet. It resurfaces related content you've seen in the past when you search the web or read articles, allowing you to remember more within your usual workflow and eliminating the need for multiple open tabs. Heyday enhances most search engines and can also surface content from apps like Notion, Google Docs, Dropbox, Evernote, and Slack. The extension installs quickly and saves and resurfaces pages alongside search results, highlights keywords you've researched in the past, and curates pages you spend the most time reading into topics to improve your retention. In terms of privacy, Heyday encrypts all content, does not sell data, and the privacy policy is available on their website.
