Pearltrees

Pearltrees turns collected links, notes and files into a visual web, so people who research, curate or organise ideas can keep related pieces together. By our assessment, it is best at showing connections rather than just stacking bookmarks, which makes it useful for messy projects and long-running reference piles. The price of that flexibility is extra setup: the tool rewards people who like arranging material and thinking in branches, and it can feel fussy if all you want is a plain list. In practice it is closer to a visual filing system than to a simple note app. Pearltrees sits between bookmarking, note taking and knowledge organisation, and Astrina files it under Productivity.
