Peek is a browser extension that leverages artificial intelligence to help users automatically organize and summarize browser tabs. By automatically grouping and summarizing content, Peek helps users stay on track with their workflow while browsing, increasing efficiency. Peek can extract hard-to-remember details like dates, prices, and names, and allows for quick reordering, merging, and nesting of themes and tasks. Additionally, users can add notes to tab groups, allowing ideas and tabs to move as a unit. Peek's goal is to help users explore the internet without getting lost.
