Saga is a collaborative workspace for notes, docs, and tasks, integrating AI. While it offers organization, sharing, and a clean interface, it doesn't explicitly focus on URL curation with instant inline previews as a primary feature. Its core is more about general knowledge management and team collaboration, rather than specifically curating web links with rich previews and contextual side notes in the 'Tufte-style' as described in the URList concept. It does have features like 'Media embeds' which could be interpreted as URL preview, and 'Public pages and workspaces' for sharing, but the emphasis is different.
