Pearltrees

Pearltrees is a collaborative platform for organizing and sharing digital content. Users can save web pages, files, photos, and notes into customizable collections and sub-collections. It offers features for public and private sharing, team collaboration, and is accessible across various devices.

Pearltrees is a strong match for URList. It allows users to organize web pages, files, photos, and notes into 'collections' (lists) and 'sections' (sub-folders), which directly aligns with 'List & Section Organization'. It supports adding notes to items ('contextual-side-notes') and offers public sharing of collections. The platform emphasizes saving various content types, including web pages with a 'web clipper' and files, which covers 'URL Saving & Preview' and 'Instant Link Adding'. It also supports rich media previews. Pearltrees offers both free and premium accounts, indicating 'Sign-In & Authentication', and allows for private collections for premium users, aligning with 'Granular Sharing Permissions'. The interface is clean and focused on content, and it's available on mobile devices.
