Tools for saving, annotating and organising links for study and knowledge work.

How we picked these

We weighed annotation and highlighting features, how well each tool organises and searches large collections, cross-device sync, and value including free tiers. We favoured tools built for durable personal reference over public sharing, and note the trade-offs for each.
