Raindrop.io

Raindrop.io is a bookmark manager that stores more than a URL. When a page is saved, the service captures its content and produces a permanent readable copy, so a bookmark survives the original page changing or disappearing. Organisation is by collections and tags. A collection can be nested and shared, and a saved item can carry tags, a highlight, and an annotation. A full-text search runs over the captured content rather than only the title, which is what makes a large archive useful rather than a list of links. The product has free and paid tiers, with the paid tier adding full-text search across the archive, permanent copies, and larger uploads. It works across browsers and mobile, and imports from other bookmark services. The limitation is that it is a personal archive tool rather than a collaborative knowledge base: shared collections exist, but the product is not built for team editing.
