When reviewing web content with notes or comments, the right tool can depend on both source material and collaboration needs. Compare annotation modes and document support, then check browser capture and export options for handling content and resulting work. Collaborative review, guest access, and team seats help distinguish ways to work with others; free-plan availability and paid-from pricing add cost context. Pastel, Weava Highlighter, and Annot8 are among the tools covered, alongside AnnotationBase and Hypothesis. Compare the published features against how you collect, mark up, and share feedback.
31 web annotation tools ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
